You need to own the regular version found in the Hunters Nightmare for the Uncanny and Lost versions to appear in that store.

Saif translates to literally sword or blade in Arabic.

It means sword in Arabic.

It wont scale with arcane unless u have an elemental type gem in it . then u will see stats go up when u level up arcane skill

I think you have to add fire, bolt or arcane runes to the weapon and more arcane means more damage. That's what I did for the whirligig and it works really well. And you can find a fire rune relatively early.

All weapons have arcane scaling pretty much

right. but if I put an elemental type gem, my physical damage is automatically replaced and it's ONLY arcane then huh? thanks for the answers

Not sure what the guy above me is on about with the gem shapes. You definitely can get radial elemental gems. A radial fire gem drops for killing the Watchdog in the Defiled Chalice as one example.

@wut? They scale with Arcane only if you put in an elemental gem first (the wanning one or triangle type not radial) and then weapon starts to scale with yout arcane atribute. And only ARCANE atribulte, str/skill scaling is replaced. Only weapons like Tonitrus, amygdalan arm, MGS, BoM, they have the split damage physical and arcane so they would benefit from two types of gems actually (and te best idea is to put an ATK UP on the weapon that rise both physical and elemental types of damage in the same time)

Is this still good with a strength build?

I'm using this plus Burial Blade with strength/skill/arcane 25/50/25. NG++. No problems whatsoever.

I would not use it with a strength build, skill only would be the best. About the slots, go with the uncanny. I went with the normal bc I have a waning gem with 26,3% phys dmg.

Depends on what you want. The Saif is quicker and has more maneuverability compared to the Pick. On the other hand, the Pick has hyper-armor while unleashing a charged attack, and like the Cane, has both Serrated AND Righteous bonus damage, which practically ensures that it will be dealing more damage than the Saif about 90% of the time. I suggest you get both, Saif for PvP and Pick for PvE. Though PvPskills on youtube has pointed out the Pick is just as good in PvP as well.

How do you do that with a flamesprayer then?

just parry him. Hunter enemies are simple to deal with that way.

Use something other than the flamesparyer. You should have at least one firearm that can stagger.
