Living Flame should do 30% of the burn damage to other enemies, i believe. However, more often than not it does 0 damage.
Have also noticed that my Lethal Smog’s Spit Poison trait no longer works after switching to Cleric specialisation. Is this working as intended? Guessing it only procs after the creature takes damage - now i’m a cleric all the damage is being absorbed by Barrier, therefore Spit Poison won’t activate?
