Dropkick

Your basic attacks and abilities execute enemy champions below 4% (+ 5.5% per 100 base AD) (+ 1% per 1000 bonus health) of their maximum health, which causes their corpse to be sent flying away in a line. Upon collision with an enemy champion or terrain, the target's corpse explodes to deal 150 – 500 (based on level) (+ 100% bonus armor) (+ 100% bonus magic resistance) magic damage to nearby enemies. Successful executions heal you for 100 – 300 (based on level) (+ 25% bonus health). The execution may also be triggered by the explosion and ignores shields.
