Heimerdinger Ability (LoL): UPGRADE!!!
Heimerdinger empowers his next basic ability, also making it free to cast. Empowered abilities share the same cooldown as their basic form. Heimerdinger can activate UPGRADE!!! again after 3 seconds of activating it to cancel its effects. Canceling UPGRADE!!! puts it on a 3 second static cooldown. UPGRADE!!! will only go on cooldown if Heimerdinger used an empowered ability.
