Active: Irelia dashes to the target enemy, dealing 5 / 25 / 45 / 65 / 85 (+ 60% attack damage) physical damage, applying on-hit effects and healing herself for 12 / 14 / 16 / 18 / 20% of her total attack damage. Bladesurge deals 55 / 75 / 95 / 115 / 135 bonus damage to minions.
Bladesurge's cooldown is refunded if the target was marked or dies to Bladesurge.
This gives you some massive burst. With a Bloodthirster (fully stacked) & Trinity Force (these two are a very good combo by the way), ~900 damage with this combo. Pretty good burst to scare off an opponent.
