This ring is somewhat counterpart to Krysbin’s sentence for Necromancer class. They both provide a 300% damage boost to the character with a condition. but one of them is working with the character’s pets (Necromancer) and the other doesn’t (Which doctor). I know at some point this was intended for balancing reason but don’t you think it is time to remove this restriction?
Make Ring of Emptiness to work with pets.
