Cooldown: 6 / 5 / 4 / 3 / 2

The enhanced attack does not trigger against structures.
Bonus Physical Damage:30 / 35 / 40 / 45 / 50% AD
Silver Bolts
Passive: Consecutive attacks and abilities mark Vayne's target with silver rings. The third consecutive attack or spell against the same target will consume the rings, dealing true damage equal to a flat amount plus a percentage of the target's maximum health (capped at 200 against monsters).
The rings are removed if Vayne attacks a different target or doesn't attack for 3 seconds.
Active: Vayne fires a projectile at target unit, dealing physical damage and knocking the target back 470 units. If the target is knocked into a wall, the target takes the same damage again and is stunned for 1.5 seconds. Condemn also applies Silver Bolts once.
Active: Vayne temporarily gains attack damage and enhances her other abilities. While Final Hour is active, Night Hunter's movement speed increase is tripled, and using Tumble stealths Vayne for 1 second.
