Dendrobate 100% Poison Damage?

How much is the 100%? Will that double all my Poison damage?

Don’t know how much dps the 100% is and i think should i use Belly or Dendrobate?

Thx

it's increased which stacks additively with all other increased. the marginal multiplier (i.e. "double" with/without Dendrobate would be 2.00x marginal multiplier) will almost certainly be less than 2.00 but would depend on how much increased you already have. if you want to know the marginal multiplier then you need to know your existing increased damage multipliers that apply to Poison and then calc the ratio between new vs. old

for example suppose you have 80% increased damage with ailments, 40% increased poison damage, and 30% increased chaos damage

your current multiplier is (1 + 0.8 + 0.4 + 0.3) = (2.5)

if you stack on perfect dendrobate on top of that it becomes (1 + 0.8 + 0.4 + 0.3 + 1.0) = (3.5)

3.5/2.5 = 1.40 or "40% more damage" (it's 1.40x compared to 2.00x being "double")

What build are we talking about?
