Yes, more like a mix of this and Zed ult from LoL.
Death Mark
ACTIVE: Zed becomes untargetable for 0.75 seconds and dashes to the target enemy champion. Upon arrival, he marks the target for death and spawns a shadow that lasts for 6 seconds at the cast location. Reactivating Death Mark will cause Zed to swap places with this shadow.
After 3 seconds, Death Mark will trigger, dealing flat physical damage plus a percentage of all physical and magic damage dealt to the marked champion while it was active.
