Zed's slash reduces the cooldown of Living Shadow by 2 seconds for each enemy champion struck. His shadow's mimicked slash slows enemies for 1.5 seconds.
Living Shadow: Overlapping Shadow Slashes striking the same enemy deal no additional damage but will apply a stronger slow and restore energy based on the level of Living Shadow.

Death Mark
Range: 625
Cooldown: 120 / 100 / 80
Cost: No cost
Active: Zed becomes untargetable and dashes to target enemy champion. Upon arrival, he marks the target for death and spawns a living shadow behind the target. This shadow lasts 4 seconds and mimics Zed's abilities. Reactivating Death Mark will cause Zed to switch positions with this shadow.
After 3 seconds, the mark will detonate, dealing physical damage equal to 100% of Zed's attack damage plus a percentage of all magic and physical damage dealt to the target by Zed and his shadows while the mark was active.
