Paladin and Demon Slayer Skill

Threathen : -50% def [with hyper]
Demon Cry: -20% def

question :
1) this 2 skill will stack at boss ? mean -70% ?

2) with ignore def 100% , did the threathen will still let u see higher dmg on boss ?

*my english so poor , =x hope understand

1) It stacks multiplicatively for -60% def. 1-(1-.5)(1-.2) = 1-(.5)(.8) = 1-.4 = .6

2) If you have 100% ignore Threaten will not increase your damage.

I remember threating only working 50% against bosses or was that changed?

Yeah it has a success rate. You just cast it until it works.

No i meant that the Def reduction was halved against bosses. Instead of -50% def it gave -25% def.

Oh idk about that.

Only the Accuracy debuff is halved on bosses I believe. The duration and effectiveness gets reduced.

And maybe that's why kms made those weirds changed to the ignore pdr, i guess
