Huh... I can't say I am shocked... I thought the Dragon Cult Incantations were the Dragon Spells.

I wonder if the damage from these spells, with a +20 Gravel Stone Seal is really crappy, or if I'm doing something wrong. I am level 105, I have 50 Faith +5 from talisman (and using the talisman that boosts Incantations), I hit enemies with the Lansseax's Glaive for like, 400 damage. There is something wrong, I don't know. Lightning Spear hits for about 700. Is this is? Or am I messing something here?

In Dark Souls, this was the magic that destroyed the dragons. In this game it is now the magic used by the dragons. Case in point….





YOU WERE THE CHOSEN ONE! YOU WERE SAID TO DESTROY THE DRAGONS NOT JOIN THEM!

Been going full dragon cult for most of the game, and to anyone considering it, I say this. Don't.

The dragon cult incantations absolutely suck ***, with one exception: Lightning Spear.
Ignoring the general problems with being pure faith for the moment (can't use a sacred weapon and buff it with incantations, faith is the only stat with no secondary benefit, heals spells are insanely slow, incantations are slow in general given lack of dex, high need for talisman slots just to make incantations passable, etc etc...), the spells in this category are just plain bad.
Honed Bolt is okay if you expect that your target isn't going to just walk up and hit you while chain-casting it. They will, though. Might as well just throw Lspears instead.
Lightning Strike is a sort of combined LSpear + HBolt, and worse than both. It's slow, hard to aim to get multihits, and enemies that are fast enough can walk through it.
Glaive looks wicked cool but has a hilarious 4s casting time even with the casting speed talisman. Any hit will not just stagger you, but FLOOR you as you're in the air. It deals about a spear and a half if you hit up close, or about half that if you hit with just the sparks. It'd be a really good and fun crowd clearing spell if it casting with reasonable speed or you could tank a hit while casting. As such you're just gonna get hit out of the animation basically every time you want to use it. Fun fact: invader-type enemies can jump over the glaive and hit you with a jumping attack. They will.
Frozen lightning is similar. Stupid long cast time, get floored if you take a hit. The nice thing is that it at least deals strong damage against big targets, possibly doing 3~6 lightning spears worth if the target is huge and you land it just right. You won't, though, since enemies aren't stationary and the cast time is so long. Also enemies can sometimes just run through it and take no damage.
Dragonbolt's main benefit is more of a PvP one; if you want resists you generally use other incantations.
Vyke Dragonbolt is a crappier electrify armament + vanilla dragonbolt, but trades enemy-hit-rebound for equip load bonus. Who the **** wants limited duration equip load bonus.
The other spells come so late in game that they're basically nonexistent.

Skip this whole incantation category. Fromsoft hates Faith and hates these spells especially.

Anyone looking to trade for one of these? Missed it on my first playthrough just started new game plus. Can drop Id on PS if anyone is interested

They're very slow, maybe they're affected heavily by cast speed though? Lightning affinities scale with Dex, so maybe that's a hint from From that lightning needs dexterity to wield effectively?

Well....
At least Lightning Spear is good?

a lot of these need heavy buffs

So most of the spells are unfortunately weaker in terms of usability. Lightning spear is solid in terms of range and cost, while Lightning Strike allows for some good dps when you continuously cast it. Other than that, the Ancient Dragon Cult spells suck, while some of the higher damage and flashier dragon cult spells come from later dragon bosses.
