Makes sense. someone else also told me that clinkz' E gets a 2nd charge on level 3; this way your charge timer keeps ticking down even when it's off cooldown. You can use this to kill jungle big creeps more efficiently. That's why they level it only to level 3, instead of maxing it, which I originally thought. Moreover, you can use death pact before going in a fight to give yourself a health buffer, then use it during the fight to heal yourself.
