Shen Ability (LoL): Twilight Assault

Shen recalls his Spirit Blade to his location. Enemies the blade collides with are slowed by 15 / 20 / 25 / 30 / 35% for the next 2 seconds when moving away from Shen.

Once it arrives, Shen empowers his next 3 basic attacks within 8 seconds to gain 75 bonus range and deal 5 / 10 / 15 / 20 / 25 / 30 (at levels 1 / 4 / 7 / 10 / 13 / 16) plus 2 / 2.5 / 3 / 3.5 / 4% (+ 1.5% per 100 AP) of target's maximum health as bonus magic damage.

If the Spirit Blade collides with an enemy champion, the empowerment is enhanced, dealing 2% (+ 0.5% per 100 AP) of the target's maximum health as bonus damage and Shen gains 50% bonus attack speed.

Twilight Assault deals double damage to monsters, up to a maximum of 75 / 100 / 125 / 150 / 175 bonus damage.
