Quinn Ability (LoL): Harrier

Valor periodically marks a nearby enemy with Vulnerability for 4 seconds. If Quinn attacks a vulnerable enemy, she deals bonus physical damage equal to 10-95 (+1.16-1.5 per attack damage) depending on her level. This also activates on enemies hit directly by Blinding Assault and Vault.

Harrier is disabled while Behind Enemy Lines is active and for 8 seconds after a target's mark ends, though this cooldown is reduced by 1% per 1% critical strike chance, multiplicatively (ex. at 50% Critical Strike Chance, Harrier's cooldown is ~5 seconds, at 100% Critical Strike Chance, the cooldown is ~3 seconds)
