Nocturne Ability (LoL): Umbra Blades

Nocturne's basic attack is periodically enhanced, dealing 20% of his physical damage to his target and 120% of his physical damage to surrounding enemies, while also healing himself for 15−40 (+15% of ability power) per enemy hit (depending on level).

Umbra Blades' damage to the primary target can critically strike for bonus physical damage.

Basic attacks reduce Umbra Blades' cooldown by 1 second, increased to 3 seconds against monsters and enemy champions.
