Passive good although OP when he has high amounts of CDR, Q is good, high base damage, W is an interesting mechanic with balanced damage, but 6 second cooldown seems low, at 40% CDR it would be 3.6 seconds (or less with passive), and the debuff lasts 5 seconds. Potentially OP. E is good, free void staff is always great. Ult: say you remove 3 duration buffs resulting in 15% increased damage, the damage would be 460 +80%ap, maybe needs to a bit higher, doesn't seem as good as an "ult" should be. But then again look at Karma
