Everything You Need to Know About Blood Gems

Everything You Need to Know About Blood Gems

Last updated on October 22nd, 2018

Blood Gems in Bloodborne come in a variety of different shapes and effects. This guide will help you on your path to getting exactly what you’re looking for!

Gems Come in 5 Different Shapes: Radial, Triangular, Waning, Circular, and Droplet.

  • Radial Gems can be found in Pthumeru Dungeons and are the most common gem in the game.
  • Triangular Gems can be found in Isz Dungeons.
  • Waning Gems can be found in Loran Dungeons.
  • Circular Gems (typically Pulsing, Warm, or Bloodtinge Gems) only drop from certain enemies in the game, including Bloodlickers and Ritekeepers.
  • Droplet Gems are a rare gem type that can fit into any slot, no matter the shape. Besides the ones you find as loot, the only Droplet Gems that drop from enemies are from the Winter Lanterns in the Nightmare Frontier and Nightmare of Mensis. Unless the DLC changes this, Droplet Gems are weaker than the other Gem types, but are a good intermediate gem to use until you can farm higher level Gems.

Notes:

• There is about a 2% chance for any gem dropped by an enemy to be an abnormal shape from the one that enemy usually drops (ex. Isz Watchers dropping a Waning gem).

• Hunter NPC’s, drop the same gem shape regardless of the Dungeon they reside in! Farm the Bone Ash Hunters for Radial, The Cainhurst Hunters for Triangular, and the Logarius Wheel or Beast Claw Hunters for Waning gems.

• The Loran Silverbeast has almost the exact same drop list as the Hunters, but can drop up to rank 19 gems (waning, barring abnormal shape drops) while the Hunters only drop up to rank 18.

Basic Primary Effects (Some can also be found as Secondary Effects):

  • Tempering:  Boosts all Physical AR by a %, including Blood ATK.
  • Adept Blunt: Boosts Blunt AR by a %. Does not boost visceral attack damage.
  • Adept Thrust: Boosts Thrust AR by a %, and visceral damage (unlike Blunt).
  • Striking: Boosts total AR on Charged attacks by a %.
  • Fool’s(tempering):  Boosts Physical AR by a % AT FULL HP.
  • Fool’s(nourishing):  Boosts total AR by a % AT FULL HP.
  • Poorman’s(tempering):  Boosts Physical AR by a % AT LOW HP.
  • Poorman’s(nourishing):  Boosts total AR by a % AT LOW HP.
  • Beasthunter: Boosts total AR by a % vs. Beasts.
  • Kinhunter: Boosts total AR by a % vs. Kin.
  • Nourishing: Boosts total AR by a %, and visceral damage.
  • Dirty: Adds Rapid Poison effect. After enough Poison buildup, the effect will activate, dealing 100 + 10% of your enemy’s max HP in damage. This type of Gem is weak compared to damage gems due to the numerous hits required to inflict it.
  • Murky: Adds Slow Poison effect. After enough poison buildup, the effect will activate, causing your enemy to slowly lose HP over a short period of time. This type of Gem is most useful in PvP, but requires several hits to inflict it and has very low damage per second.
  • Bloodtinge: Boosts Blood AR by a %. This gem type is used for guns and the Chikage’s transformed mode. Does not affect Visceral damage.
  • Heavy: Boosts Strength scaling with a Flat % of your base AR, relative to the Strength stat. The effects of this Gem are weak compared to the % Gems. See explanation in the Gem Formula section of this guide.
  • Sharp: Boosts Skill scaling by a Flat % of your base AR, relative to the Skill stat. The effects of this Gem are weak compared to the % Gems. See explanation in the Gem Formula section of this guide.
  • Warm: Boosts Bloodtinge scaling by a Flat % of your base AR, relative to the Bloodtinge stat (only applies to weapons with inherent Blood AR). The effects of this gem are weak compared to the % Gems. See explanation in the Gem Formula section of this guide.
  • Cold: Boosts Arcane scaling by a Flat % of your base AR, relative to the arcane stat. This effect ONLY boosts Elemental scaling, so it is useless on any weapon without a tied element. The effects of this Gem are weak compared to the % Gems. See explanation in the Gem Formula section of this guide.
  • Fire: Boosts Fire AR by a % Changes the damage type of a purely Physical weapon to Fire and causes it to scale with your Arcane stat.
  • Bolt: Boosts Bolt AR by a %. Changes the damage type of a purely Physical weapon to Bolt, and causes it to scale with your Arcane stat.
  • Arcane: Boosts Arcane AR by a %. Changes the damage type of a purely Physical weapon to Arcane, and causes it to scale with your Arcane stat.
  • Pulsing: Causes your character to regenerate HP over time. These gems are useful for passive regeneration on builds that don’t have powerful guns.
  • Odd Tempering: Adds a flat amount of Physical AR (not affected by Attack Modifiers).
  • Odd Fire: Adds a flat amount of Fire AR (not affected by Attack Modifiers).
  • Odd Bolt: Adds a flat amount of Bolt AR (not affected by Attack Modifiers).
  • Odd Arcane: Adds a flat amount of Arcane AR (not affected by Attack Modifiers).
  • Radiant: Reduces your Stamina Cost by a %. One of the least useful Primary Gem effects, but is a useful Secondary effect for high-stamina-usage weapons.

Secondary Effects That Cannot be found as Primary Effects:

  • Finestrike: Boosts your AR on attacks vs. Open Foes by a %. By “open”, the game means a target that is in the process of attacking, dashing, or dodging. Perhaps the most useful and powerful secondary effect for PvP Gems. Does not affect Visceral damage.
  • Odd Bloodtinge: Adds a Flat amount of Blood AR (not affected by Attack Modifiers). Does not affect weapons without inherent Blood AR.
  • Dense: Increases your weapon’s Durability.
  • Fatal: Increases your Rally Potential. This is the time period in which you can earn HP back by attacking enemies with Melee.

Cursed Gems are the best you can get, but they come at a cost:

  • -ATK: Reduces total AR by a percentage. Gems with this Curse are almost useless.
  • -ATK vs Beasts: Reduces total AR against Beasts by a percentage. Doesn’t affect damage against other players.
  • -ATK vs Kin: Reduces total AR against Kin by a percentage. Doesn’t affect damage against other players.
  • +Stamina cost: Increases Stamina Costs of your weapon by a percentage. One of the least detrimental Curses.
  • -Weapon Durability: Causes your weapon to lose Durability faster.
  • HP gradually depletes: Reduces your HP over time.

How do Gem Effects Stack?

Effects such as Odd Tempering, Slow Poison, Rapid Poison, and scaling from Heavy/Sharp/Cold/Warm Gems add together. Matching % effects multiply together. Here’s a little math to show how:

  • One 10% Tempering gem multiplies your gem-less physical AR by 110%, or 1.1.
  • Two 10% Tempering gems on the same weapon = 1.1 x 1.1 = 1.21

Because of this, stacking the same effects is most beneficial, but these effects don’t always have to be identical. If you were to have a 10% Arcane gem with +10% ATK up vs. open foes, your AR would be 1.1 times your gem-less Arcane AR on normal hits, and 1.21 times your total gem-less AR on attacks vs. open foes (not including the inherent 20% open hit bonus). While gems with pure effects (such as those given by the Scurrying Beasts and the Merciless Watchers) will reliably give you the effect in every applicable situation, they will not always be the most powerful gems.

Let’s compare a 32.6% Blunt Gem from the Watchers and a 28.7% Blunt Gem with +5.6% ATK vs. Open Foes from the Undead Giant. The Watchers’ Gem gives you a constant effect of 1.326 times your Blunt AR. On the other hand, the gem from the Undead Giant only gives you a constant effect of 1.287 times your AR. Neverthless, it has the potential to multiply your Blunt AR by 1.359, and any other inherent Elemental AR on your weapon by 1.056, on open hits.  This ideally shows us why the Finestrike secondary effect is perfect for mixed-AR weapons. Looking at the way gems stack, we can reason that the AR difference between these gems is amplified with each additional synergetic effect, as shown below:

  • 3 Merciless Watchers 32.6% Blunt gems = 1.326^3 = 2.33
  • 3 Undead Giant 28.7% Blunt + 5.6% ATK up vs open foes = (1.287 x 1.056)^3 = 2.51 on attacks vs. open foes

Even though the ATK vs. Open Foes effect was 5.6%, the total Physical AR gained from 3 of this effect is 18%. Simultaneously, you get that 18% for any Elemental AR as well.

Do other effects like Rally Potential, Beast/Kinhunter, or Curses stack like this? Yes, so be wary of this and allocate your gems accordingly. Stacking the same curses, such as increased stamina cost, on the same weapon can become problematic if you’re not careful.

The Gem Multiplier Formula:

  • [(Gem Effect A%/100)+1] • [(Gem Effect B%/100)+1] . . . = Gem Effect Multiplier

If you have multiple Gems with the same effect(s), you can use exponents to simplify the Formula accordingly:

  • [(Gem Effect A%/100)+1]^n[(Gem Effect B%/100)+1] ^m . . . = Gem Effect Multiplier

Where n represents the number of identical effects for Effect A, and m represents the number of identical effects for effect B. These formulas will only tell you statistical AR, and will not account for any Attack Multipliers such as those given by your weapon’s moveset or by counterhits (aka. attacks vs. open foes).

To ensure accuracy in your calculations, be sure to apply the Formula for each applicable Damage type on your weapon. If a Gem has any +ATK effects, those effects will apply to all attributes on your weapon. This simply means that +ATK on the Burial Blade would be applied to both the Physical and the Arcane AR. On the Stake Driver, +ATK would only affect the primary damage attribute of its respective Element or all Physical attributes (as applicable). Blunt and Thrust AR boosts only affect their respective attribute and have no impact on any other AR type. Flat AR increases from Odd gem effects must be made after all % effects are taken into consideration.

Scaling Gems are similar to % effects, but have some major flaws: they don’t reach their full potential until you hit 99 in the scaling stat that they depend on; they are additive rather than multiplicative; and they only multiply part of your AR.

  • One +27.2 scaling Gem = 1.272 times your base AR + your Gemless scaling AR at 99 in the scaling stat of your gem
  • Two +27.2 scaling Gems = 1.544 times your base AR + your Gemless scaling AR at 99 in the scaling stat of your gems

Here’s an example:

The Logarius Wheel with 99 Strength has 200 base Physical AR and 220 scaling Physical AR…

  • With 1 scaling Gem = (1.272 x 200) +220 = 474.4 AR
  • With 2 scaling Gems = (1.544 x 200) +220 = 528.8 AR

By comparison, % Gems multiply all AR in their respective category, regardless of your stats.

  • With 1 percent Gem = 1.272 x 420 = 534.2 AR
  • With 2 percent Gems = 1.272^2 x 420 = 679.6 AR

As you can see, one % Gem outranks 2 scaling gems. The difference between them only increases when you have less than 99 in your scaling stat. Furthermore, scaling gems only affect 1 stat’s scaling, whereas % gems multiply AR regardless of scaling. For this reason, scaling gems are almost completely useless.

Useful Gem Multipliers:

  • Three 5.6% effects = 1.178 times AR for your respective Damage type
  • Three 12.6% effects = 1.428 times AR for your respective Damage type
  • Three 21% effects = 1.772 times AR for your respective Damage type
  • Three 23.1% effects =1.865 times AR for your respective Damage type
  • Three 27.2% effects = 2.058 times AR for your respective Damage type
  • Three 32.6% effects = 2.33 times AR for your respective Damage type (or all AR’s if Beast/Kinhunter)
  • Three 36.3% effects = 2.53 times AR for your respective Damage type

So, now that we have all of the Shapes, Effects, and the Gem Multiplier Formula laid out, what Gems do I want to use? It entirely depends on your stats and the weapons you want to use.

Pure Physical Builds (Strength, Skill, or Strength and Skill): These builds are the easiest to farm for and use the most basic Gems. Tempering is your best bet here. Adept gems can be used to strategically boost the damage of specific attacks that you use most often, such as Thrust for Reiterpallasch and Blunt for the Logarius Wheel. Other gem types can be used, but they will often result in severe limitation of your effectiveness.

Bloodtinge Builds: These builds can use the both Tempering and Bloodtinge Gems to great effect. Tempering covers Blood Attack – as well as Slash, Thrust, and Blunt – because it is considered a Physical attribute. Bloodtinge gems are a little more powerful than Tempering for increasing Blood AR, such as on the Chikage’s transformed state, but greatly limit your style of play.

Arcane Builds: These builds use different Gems from the other 2 build types listed. Elemental Gems allow you to use your Arcane stat scaling on otherwise purely Physical weapons. Nourishing Gems can be used to supplement purely Elemental weapons since Elemental Gems are difficult to farm for compared to the other Gem types. They also help boost the weak Viscerals that Arcane builds often suffer from, and work well for boosting the AR on split-damage weapons such as the Logarius Wheel and Tonitrus. This build type can also use Beasthunter and Kinhunter gems better than any other build because they function in the exact same manner as Nourishing Gems against their respective targets, making their use on split-AR weapons quite effective. The key here is exploiting weaknesses, so bear that in mind when you choose your gems. For more information on this build type, please refer to the Pure Souls Arcane Guide.

 

Where do I get these Gems? The Chalice Dungeons, of course!

Before getting into glyphs and enemies for gem farming, a word of caution: Eye Runes have been statistically proven to NOT improve the quality of gem drops. Their only use in farming is making an enemy with less than 100% total drop rate drop their items and gems more often. Bosses and some enemies, such as the Labyrinth Madmen and Scourge Beasts have a 100% drop rate of SOMETHING from their drop list, so Eye Runes won’t help. NPC Hunters and Lost Child of Antiquity (Gargoyles), on the other hand, have a low overall drop rate that greatly improves with high discovery.

Tempering:

  • Common drop from The Merciless Watchers (up to +27.2% Physical with no secondary effect) in RFC Ihyll ag77rinb or pwmf22gu; and RFC Isz 5pwujscd.
  • Common Drop from The Labyrinth Madmen (up to +21% with a strong secondary effect) in RFC Ihyll pwmf22guuncommon in RFC Loran Glyph 25dzpyg3.
  • Guaranteed drop from the Bloodletting Beast (up to +24.8% Physical ATK with a random secondary effect) in RFC Ihyll 42t2cns6 Layer 3.

Gem Guide 1

Adept:

  • Guaranteed drop from the Undead Giant (up to +28.7% Thrust/Blunt with a random secondary effect) in RFC Ihyll 28nt7p5z; RFC Isz u37b5h48RFC Lower Loranfmkivi7n Layer 2.
  • Uncommon drop from The Merciless Watchers (up to +32.6% Thrust/Blunt with no secondary effect) in RFC Ihyll ag77rinb or pwmf22gu; and RFC Isz 5pwujscd.
  • Rare drop from the Labyrinth Madmen (up to +24.3% Thrust/Blunt with a strong secondary effect) in RFC Ihyll pwmf22gu; and RFC Lower Loran 25dzpyg3

Gem Guide 2

Nourishing:

  • Guaranteed drop from Amygdala (up to +21.5% ATK with a random secondary effect) in RFC Isz ghgvhb2d; and RFC Lower Loran ske4igwv.
  • Guaranteed drop from Rom the Vacuous Spider (up to +19.5% ATK with a random secondary effect) in RFC Ihyll v5v5fpsd.
  • Rare drop from the Cainhurst Gargoyles (up to +19.3% ATK with a random secondary effect) in RFC Ihyll pwmf22gu; (Please note that these gems become common with high discovery and are very fast and easy to farm, making the farming of Rom almost obsolete).

Gem Guide 3

Beasthunter/Kinhunter:

  • Rare drop from the Cramped Caskets (up to +27.7% ATK vs Beasts/Kin with a random secondary effect) in Layer 3 (pre-area) of RFC Ihyll exdy2m2t (Please note these become common drops with high discovery; use Eye Runes).
  • Rare drop from the Hunter NPC’s (up to +27.7% ATK vs Beasts/Kin with a random secondary effect) in RFC Lower Loran 25dzpyg3.

Gem Guide 4

Bloodtinge:

  • Common drop from the Shotgun Merciless Watcher (Circle Gem up to +31.5% Blood ATK with no secondary effect) in the first pre-area of FC Ihyll e99tdh9f.
  • Common drop from the Bloodstarved Beast (+28.7% Blood ATK with random secondary effect) in RFC Lower Loran jvz8469j.
  • Uncommon drop from the Ritekeepers (aka Fire Witches; sometimes they drop Radial gems) in RFC Ihyll v5v5fpsd. Please see this video for farming the Witches: https://www.youtube.com/watch?v=kY5A-WJY9f0

Circular Bloodtinge Gems can also be farmed from Bloodlickers found in the dungeons. There is a small chance of them dropping Bloodtinge Gems in the corresponding shapes: Triangular (Isz), Radial (Pthumeru), and Waning (Loran). To get a Bloodlicker to spawn, simply use a visceral attack or backstab in a Chalice Dungeon. Only certain enemies will yield you a Bloodlicker, and only the first Visceral/Backstab on an enemy will be the spawning location of a Bloodlicker. Here is a list of them…

  • Merciless Watchers (all types, excluding the Fat-Rolling & Cleaver Watchers)
  • Labyrinth Madman (all types)
  • Labyrinth Warrior (all types)
  • Watcher’s Gravedigger (all types)

Once you Visceral or Backstab the enemy, leave the area (not the dungeon itself). The Bloodlickers will only appear after you have traveled far enough away or enter another area or layer. After traveling the required distance, come back to farm the bloodlickers that have spawned. Use Eye Runes to boost your Gem drop rate. Please  see the following link for an example: https://www.youtube.com/watch?v=LABylytuUnA

Credit for the Glyphs goes to ALL of the kind souls who shared them publicly and compiled them. Without their work, this guide would have been severely limited. Thanks also to EMonaghan (TurquoiseWaters) for her assistance in creating this Guide.

On a final note, once in a Blood Moon you get a unique novelty that should not even exist. When this happens, fret not, and consider yourself fortunate that you saw something so rare.

    Great guide!

  2. Avatar TSMP says:

    This is an extraordinarily good guide. There are only two small thing I’d like to mention:

    1) It says some primary effects can’t be found as secondary effects, but not which ones those were. I’ve not found Tempering, Arcane, Fire, Bolt, and Nourishing as secondary effects, if that helps.

    2) There should probably be some mention of "damage priorities", and how mismatched damage effects can potentially ruin a gem, particularly when trying to make a pure physical weapon into elemental. Arcane overrides fire, which overrides bolt, which overrides physical, which overrides nothing. For example, a waning %bolt up gem with a +fire flat secondary on a pure physical weapon would give no bolt damage whatsoever and would only add the flat fire effect.

  3. Avatar Pure_Souls says:

    Both good points. Percent effects are rather uncommon as a secondary effect. In addition to what you listed, Bloodtinge, scaling effects, and Adept effects cannot be found as a secondary effect. We’ll make sure to add that in. Thanks for the feedback!

  4. Avatar Agurzil says:

    An amazing guide! I must admit, even after spending well over 200+ hours in the dungeons, I have yet to find some of those gems, for example, I’ve never found a fool’s/poorman’s nourishing gem…

    I have not yet read through it completely, but it is a truly amazing work you’ve done.

    Just a little note: You wrote, that you cannot find "odd bloodtinge" as a primary stat on gems. This is 100% false, as I have a waning odd bloodtinge from a chest from a hintertomb (It’s closed down, but I remember it clearly because it really is an odd gem). It is not a very good gem, but so far, I’ve never ever looted a primary odd gem from an enemy. This is probably something you might want to mention as well, primary odd gems come from chests!

    I also have a question about beast-/kinhunter gems: Do they ignore enemy defense? I’m not certain, but I had the feeling that I was doing abnormally high damage to big E with a kinhunter reiterpallasch, compared to the totally stronger tempering setup I was using, same with beasthunter gems… It might false though, I didn’t test it yet, as I have exactly 3 gems of that type xD.

    Thank’s, really interesing, I’ll try to make a french version of it.

  6. Avatar kettpower says:

    Like always amazing guide, just read through it very fast, but I guess it will be a great help for anybody searching for a certain blood gem.
    One thing I would like to add is that the very annoying Witch of Hemwick enemies which appear in FRC dungeons quite often always seem to drop waning gems no matter the dungeon type. I used them to get a waning arcane gem in an ISZ dungeon, and it didn’t even take that long.

  7. Avatar Agurzil says:

    @kettpower: I can confirm this, I can even go further: Apart from only dropping waning (they can drop other forms, but then it’s an off-shape drop) gems, they also have certain loot tables for certain dungeons. So far I’ve never received an arcane gem from them in a Loran dungeon for example. I’m not entirely certain which type is tied to which dungeon… They tend to be so annoying to kill that I never bother to look at them anyway. I wonder if they have any special secondary effect?

  8. Avatar kettpower says:

    @Agurzil
    "n8j4rs7y" is a FRC Ihyll, where you can easily kill a Witch very close to the lamp on layer 1, but I’m not sure if it’s still open…. I initially wanted to use this dungeon to get my waning arcane but after half an hour of farming, the only elemental thing they dropped were fire. As this is a somewhat common elemental drop in Pthumeru I decided to search for a witch in an Isz dungeon and I got my gem pretty soon. Supposedly these witches have a huge drop table and it’s usually waning shape, IIRC someone over at Reddit mentioned it in a thread.

  9. Avatar Fexelea says:

    Another amazing guide by Pure_Souls. Really loving the commitment to Bloodborne! I’ll make sure to tweet this out to the developers :)

  10. Avatar Pure_Souls says:

    The amazing part about gems is that, even with thousands of hours of compiled research, it’s almost impossible to have every detail unless the dev’s write it all down and release it themselves. If you ever find another odd bloodtinge gem, let us know. They are either extremely rare or may have been patched out entirely from the dungeon loot tables. We’re still doing a ton of dungeon searching for rare or unique enemies that may drop specialized gems.

    Kinhunter and Beasthunter gems act very strangely, but in all of our testing, it only ever acted like a stronger version of a Nourishing gem. It’s entirely possible that they do ignore defenses, however we’ve never seen any evidence of this.

    Thank you for all of your support, Fex. We greatly appreciate it

  11. Avatar SullyStalker says:

    This article mentions "open foes" to be enemies in the middle of attacking, running, or dodging. What about enemies that have been knocked down or staggered? If these cases are included as well, then "finestrike" gems could be great for heavy weapons that have high stagger potential.

  12. Avatar BlitzKeir says:

    You guys should collaborate with Cas and Fex to put some of this on the wiki. We never found a way to helpfully and concisely represent stats on gems. I think it might be better to list min/max ranks and explain the rules for gem types rather than list stats for every tier.

  13. Avatar Sljm8D says:

    [sorry if this is a double-post, I tried earlier and it did not appear. Do I need approval for my posts to show?]

    Hello! I loved the guide, I found it very well-constructed, as are all your guides, and it taught me a few things. Highlight of the evening was learning that normal BLB drops Tempering gems. I had assumed, because of fighting Headless so often, that they both dropped Heavy gems. I’m happy to be proven wrong in this case, because some of the secondary effects are quite interesting.

    Speaking of that, I posted a little thread on reddit today with a few of my own findings about blood gems, and I thought I’d share. I signed up for Fextralife just so I could! I dunno if any of it can be of use to this guide in particular, but if so please make use of it.

    Actually, I’d like to contribute a lot more to the wiki in general, because while I love reddit’s Bloodborne community, the inherent mechanics of reddit itself don’t lend well to the sort of work I like to do, which is writing and contributing to guides like this, and to be perfectly honest most people look to the wiki for information first.

    I noticed you also have an Arcane guide published about the same time I posted mine. Also exceptional work, and I’m really pleased I’m not the only one who had that sort of thing on his mind to do.

    Hi Sljm8D – posts with links are kept for approval for new users to prevent spambots and such from link-littering the place. I approved it so now it shows :)

    You’ve done a good job with your guide as well! Please feel free to hit edit on the wiki if you find missing info you feel should be there!

    Also if you would like, you can have contributor status on our blog and write articles and guides at your leisure if it’s your thing.

    That’s a clever way to avoid spam-bots, it makes total sense. I did join the forum with the intention of helping with the wiki, in particular the Blood Gems, I’ll be around to that thread after this weekend to toss some ideas around. I’m excited to help, and I’ll be around to help with adding DLC info as well.

    I would absolutely love to contribute to the blog as well, I think that would be a better medium than continuing with Reddit in terms of visibility and longevity, and there’s no rule agaisnt pimping any articles there to drive traffic. Thanks for the opportunity!

    Thank you, I hope it doesn’t seem like I’m trying to compete with you guys, I really think this community thrives on cooperation and increasing the collective understanding. I’d much rather work with people and have everyone build on each-other’s works than to try to compete in some way. That’s part of the reason I wanted to join this forum finally. I now feel like I can actually contribute something.

    Hey, thanks for that, I added that to the reddit post. I hadn’t intended for that to be exhaustive, but that’s a pretty great example to include.

    No worries man. I like the fact we all can add something. its all for the greater good. *Grant us eyes*

    Oh, I wanted to mention I found a small error in the guide, regarding Scaling gems. You mention that the calculation multiplies only your base damage, but not the scaling… Actually the reverse is true.

    Scaling itself is based on base damage, so I can see how this error occurred. The big hint though is that Heavy/Sharp gems increase the scaling letter of the weapon you slot them into. I’ll give two examples to show the calculation: Wheel and Blade of Mercy. The former has only Strength scaling, the latter only Skill. I have 93 Strength, which according to the reddit guide by Silvard about scaling gives a modifier of 0.98163 to my Strength scaling.

    With no gems, my Wheel shows 200+215, and an S in Strength. According to the guide, this S is 1.1
    1.1 * .98163 -> 1.079793 * 200 = 215.9586, rounded down apparently.
    If I add a 23.9 Heavy gem with Charge Atk Up (so it won’t impact my AR screen), I now have 200 + 263, and a higher S.
    263 / 200 = 1.315 / .98163 = 1.339 – 1.1 = .239
    As you can see, these gems seem to add to the scaling factor, rather than being multipliers like percentage gems. This also explains their peculiar formatting, as they are written as a linear bonus.

    If I have two of these, I see 200+310.
    (1.1 + .239 + .239) * .98163 * 200
    1.578 * .98163 * 200 = 309.8, rounded up for some reason in this case, perhaps because there are more floating points on the gems than we can see. Still, it illustrates the point. A 24.8 Abyssal added on brings this to 200 + 359
    (1.1 + .239 + .239 + .248) * .98163 * 200
    1.826 * .98163 * 200 = 358.49, again rounded up likely due to hidden decimals or slight errors in Silvard’s work. In any case, I think this number is close enough to prove the point.

    This is even more perfectly illustrated on Blade of Mercy, which has 0 Strength scaling whatsoever. Adding these gems to it gives E, then D, then B Strength scaling, and I go from 120+112 without gems (I have 50 Skill), to 120+198. The difference is 86.

    (.239 + .239 + .248) * .98163 * 120
    .726 * .98163 * 120 = 85.519

    I think this looks conclusive. Thanks for your time, I hope you have an opportunity to fix this slight error in your guide.

    The point still stands! Scaling gems are poop. If anything, they’re even poopier than your guide would suggest. D:

    Reads nice, but it´s more of an expert guide rather than a guide to learn from.
    I admit I´m having trouble with some things:

    for example:
    -What does RFC stand for?
    -For those of us who can`t do the deepest Chalicedungeons (like 99% of the playerbase :) ) where do we get maybe less powerful, but way easier to obtain blood gems?
    For instance, I would be perfectly fine with a 18%damage tempering gem

  21. Astrichthyes_ says:

    In the base game, elemental gems are limited, but you can get up to 19.8% tempering droplets from the Winter Lanterns in Nightmare of Mensis (Mergo’s Middle, on the way to the Blood Rock).

  22. Astrichthyes_ says:

    I ran through your calculations and we seem to be getting the same result through different methods. Here is the method that was used for the guide:

    Weapon AR gained/Original Weapon base AR = Scaling Gem Percentage

    Your example with the Wheel was a 23.9 str scaling gem at 93 str, so I will use that to show you how our methods differ while obtaining the same result:

    No-gems wheel = 200+215 phys
    23.9 scaling wheel = 200+263 phys

    AR gained: 48
    48/200 = 0.24 <- almost perfectly matches your gem (hidden fractional AR can account for this). Rearrange the formula I used above and you get:

    Weapon Base AR * Scaling Gem Percentage = Weapon AR gained

    Total AR with your scaling gem = Weapon AR gained + Original Weapon AR = Scaling Gem Percentage * Weapon Base AR + Original Weapon AR

    So you see, the guide actually wasn’t wrong. It included the extra steps needed to get total AR from your gem by adding the original scaling back in. You are correct in the fact that the scaling factor increases, however we are yielding the same results.

    Q.E.D.

  23. Avatar arctic_dan says:

    Sorry about that , We may need to be more specific instead of using shortcuts. RFC = Rotted, Fetid, Cursed. Rites that can be added to a root dungeon.

  24. Avatar Pure_Souls says:

    They changed the way scaling gems work. I just checked and the math I did shows that it no longer depends solely on base AR.

    Fire Saw Cleaver on a 50A build:

    27.2% fire: 335AR (180+155)
    add a 21 arc scaling gem: gains 69AR

    69/180 = 0.38333
    69/335 = 0.20597

    EDIT: they completely changed the way scaling gems work. Saw Cleaver is only gaining 5 less AR than Ludwig’s. The change does not seem as simple as accounting for total AR with a similar formula to the one we used. We’ll do our best to get to the bottom of this ASAP.

  25. Avatar Sljm8D says:

    I wasn’t trying to start an argument, I just didn’t think that section of the guide was explaining the mechanics, even if the results are correct. I guess it’s a difference between our minds, I prefer to arrange formulae in a way that shows the process over giving the simplified (and still correct) version that might appear more arcane. I’m really sorry if I came off like a douche, I’m just trying to help.

    In any case the point is moot, because what the butts is going on with Scaling gems now? D:
