Ability descriptions often specify whether a bonus is additive or multiplicative, but when they don't, should we assume one or the other? As an example, from Kyre's recent blog:
Flawless Strike - Champions that attack a stunned enemy have a 100% additively increased chance to critically hit that enemy and deal 100% more critical damage.
If, for example, this bonus were in effect and a level 500 Rosie attacked a stunned enemy (because Rosie's Shadow Arts ability increases her crit damage by 100% multiplicatively for every 100 levels she has), how much would that extra 100% from Flawless Strike help? That is, would it be:
- 100% * 2^5 = 32,000% + 100% = 32,100%
- or 100% * 2^5 * 2 = 64,00
