Hello! So I recently got a cursed legendary item whose task is to use your unique power 75 times. As it is Ajax’ item, I assumed unique power meant each of his skills. I have 4 of them unlocked now, and with each battle, I make it a point to spam all 4 as much as possible. However, the said task only deducts by a seemingly “random” amount of times. To my understanding, I should be deducting 4 with each battle as Ajax has 4 unique powers. However, I’m only deducting 1 - 3, and I don’t know what makes using a unique power count.

Any insights on this?
