Bug: So I believe the perk Villainy Thrives is not working properly, at least not in conjunction with Intensity which does “After this creature attacks, it increases the potency of the target’s Poison and Burn debuffs by 50%”. Villainy thrives states “The potency of the enemies’ Poison and Burn debuffs are shared with each other but reduced by 65%. This trait does not stack.” Using these two perks would make you think that by attacking another creature would increase the potency for all the enemies but it does not. I had posted this a while ago but it didnt get any response so if I am misunderstanding something, my appologies.
Just confirming that this interaction is working as intended!
