Specifically for prebuffing venom in OS +3venom Claws, do I need to use perfect 5/5/ facets or does the -enemy resistance even take effect if I change weapons after the buff?

I've tried searching and haven't found anything conclusive. Thanks!

-resists is only applied at the moment poison damage connects, not when the venom was cast nor over time
+% poison damage applies once as you cast it, and again at the moment you connect with melee attack damage
prebuff gear could be +5/-3 facets just fine

Thanks! I'm assuming this would also work with Bramble

yes, you lose the -2 skills of course

the highest prebuff possible is 2x +6 claws with 2x facets, bramble, +3 helm with 2x facets, +3 ammy, 2x soj/bk, trangs gloves, arachs, shadow dancers, 9x charms, BC from CTA and torch/anni
that gets you a base venom of 3444 over 0.4 seconds
then its modified by +%/-% resists when you hit
both have substantial effects since they're both multiplicative. Any -% resists you have on hit will both lower enemy poison damage resist as well as poison length resist. For most people that's redundant since you have -100 base in hell and won't wear items with poison length reduce affixes too often, and its capped at the same [-100,75] as other resists, its just hidden.

If you're on a fairly normal 102% fcr setup with +25% poison damage / -0% poison resist from trangs gloves, 15/15 in helm and runes in your non-chaos claw, that prebuff would give you 366 HP over 0.8 seconds against a normal 75% resist / -100% length opponent.

Thanks for the info! Super helpful
