PASSIVE: Entering combat generates 1 stack every second for the next 3 seconds. Additional stacks may be generated by re-entering combat after 2 seconds. After reaching 4 stacks, your next basic attack on-hit within 6 seconds against an enemy Champion icon.png champion consumes all stacks to deal ( 4% melee / 2.4% ranged) of your maximum health as bonus magic damage, heal for ( 2% melee / 1.2% melee) of your maximum health, and permanently grant (5 melee / 3 ranged) bonus health. The empowered attack duration refreshes whenever going in combat.
