Have seen several posts on Reddit … want to make it known on these forums too … the new Epidemic skill seems to hurt friendly targets also.
Cannot be certain if this is intended or not, but my guess is it is a bug.
More detailed testing underway …
Preliminary details … I cast Epidemic, get 3 stacks of vulnerability and 1 stack of weakness on me, then transfer to target with dagger 4 (Deathly Swarm) and get a totally random number of condi stacks on me. One time, I had 18 bleeds plus 1 stack each of 2 different conditions on me. Another time I had 8 bleeds and nothing else. Seems totally random.
All testing done in the Special Forces traning area on a buffless golem.
