She's probably a support. Doesn't have much CC, but has a powerful heal and a number of nukes, as well as a powerful escape that acts as a combination of an Urgot's ult and a Thresh's lantern. Her ultimate is probably the best defensive ability in the game.
Whenever Zerepha damages an enemy unit, she leaves a mark on it for three seconds. Allies who damage the marked target gain movement speed equal to 2% of it's maximum health for two seconds.

Ally Cast: Heals a target allied unit and releases a wave from the target back to Zerepha which damages enemy units for a percentage of the ally's maximum health.
Active: Zerepha releases five slow-moving shades in a cone in front of her. The shades travel in a curved path from their initial straight line towards the targeted point and damage the first unit they hit, also slowing it and any nearby units by 90% for 1 second. A single target cannot be hit by more than one shade from a single Shade Pulse. The shades take three seconds to travel to a point at maximum range.
