KMST 1.2.425 - Mikhail

I didn't notice the cooldown on Enrage, however it's still a very heft buff for 4 minutes, with a 5 minute cooldown. +60% Attack, +20% Critical, +15% Min Critical Damage, and +1 Target per attack. That's way better than most characters get, even as a cooldown skill.

It isn't +1 target per attack, it's 1 target regardless of attack.
