damage buffs: additive or multiplicative?

[Icemephit]

Anyone know if damage buffs are additive or multiplicative? Say might's 20% + giant slayers 5% + channeling balance's 7.5%. I was under the assumption before that everything would be additive as one multiplier but I figured I'd ask incase anyone has figured out otherwise.

Icemephit-

Most bonuses in this game are multiplicative in nature. So yes, with the examples that you're discussing, multiplicative.

See here for an example of some of the math:

Necroing my own really old post since my new question is rather related. I'm doing another playthrough and was trying to math out the best possible damage on a few team combinations. Would anyone happen to know which things are not multiplicative? I'm mostly wondering if something like heroic party is 9 separate 1% buffs or its its additive with itself. Trying to compare it to buff mastery and multi might but the additive vs multiplicative difference starts to become a bit large when stacking multiple heroic parties(like 30% overall ish)
