He deals extra damage to enemies that have debuff, like the aforementioned Crit chance down, Buster res down, or basically any debuff you see in your enemy that has blue down arrow or is colored blue. So if you have his 1st skill at lvl 10, he deals 50% extra damage to enemies who have those debuff.

Unremovable debuff is debuff you or your enemy can't remove. Typically, bosses have this kind of debuff. You can distinguish it with removable one by looking if the debuff is placed inside a square.
