I would get a screenshot but it's a bit difficult to capture. Anyways I've found when killing Waking Flame cultists in the deadlands delves (specifically the ranged and magic users), if I fail to kill them fast enough they will drop to their knee and regain all their health, and their entire group will be invulnerable for a few seconds as this happens. It doesn't look as though a spell is causing this, rather a bug of some sorts, and it makes trying to burn through mobs to do the dailies quite inconvenient.
