Aphelios Ability (LoL): Severum, the Scythe Pistol

Severum Passive: Attacks using this weapon restores 2.5-9% of the damage dealt as health, and abilities using it restores 8.3-30% instead. This weapon can heal Aphelios over his max health, granting him a 10-140 plus 6% of target's missing health shield for 30 seconds.

When Severum is assigned, Aphelios can use Onslaught.
