Active: Tristana throws a grenade charge on a target enemy. After 4 seconds, the charge explodes and deals 60 / 70 / 80 / 90 / 100 (+ 0.5 / 0.65 / 0.8 / 0.95 / 1.1 per bonus attack damage) (+50% of ability power) physical damage in an area.
Every basic attack, Rocket Jump or Buster Shot against a target with Explosive Charge adds an additional stack that increases Explosive Charge's final explosion damage by +30%, stacking up to 4 times (+120% damage). The Explosive Charge will detonate immediately upon reaching maximum stacks.
Explosive Charge can be cast on towers and has a larger explosion radius than on a unit.
