Thunder Forge tier1 upgrade, specifically 1st Degree Burns
Question on how to interpret "1st Degree Burns" definition:
On Hit: Applies a stack of Vulnerable (1% more damage for 3 seconds. This effect stacks up to 20 times, and loses one stack on expiration.) This effect may only occur on-hit once every two seconds.
Does this mean a mob gets up to 20% more dmg applied?
Or does this mean I get 20% more dmg per swing, which would apply to all mobs I hit?
I'm assuming its the later, but I've made an "you-me" of myself one too many times, so want to know if anyone has tested or knows for sure.
