Morgana Ability (LoL): Tormented Shadow

Morgana infects the target area for 5 seconds, causing enemies who stand on the location to take 6 / 11 / 16 / 21 / 26 (+7% of ability power) magic damage each half second, increased by up to 170% based on the enemy's missing health. The total damage is increased by 155% against non-epic monsters.

Over the full duration, Tormented Shadow deals a total of 16.2 / 29.7 / 43.2 / 56.7 / 70.2 (+18.9% of ability power) magic damage each half second, scaling up to 162 / 297 / 432 / 567 / 702 (+189% of ability power) depending on the enemy's missing health.

Tormented Shadow's current cooldown is reduced by 5% of its maximum whenever Soul Siphon triggers. Simultaneous triggers from multiple targets will stack the cooldown reduction.
