Are convert passives additive ?

[Sarakash]

See title,

 

I was just wondering if convert skills like one handed mastery and dirty fighting are additive. Wouldn´t make sense to me otherwise, but I ve yet to find a roll in the log where it happened and how it gets calculated.

 

Next thing I was wondering if a single attack can be converted several times, from graze to hit and then from hit to crit for instance.

They are checked one after the other and his are multiplicative - meaning that the more conversions to add the less impact they have individually.

 

If you'd have a 50% conversion and another 50% conversion you'd have 0.5 * 0.5 = 0.25 (which would be the chance NOT to convert). So rather than getting 100% you'll get 75%.
