Shike, the Embodiment of Time

Lore: "My eyes, saw upon a being of such ancient power and strength, one whose power rivaled that of the Caretaker himself. My knees fell, and I let out a scream, a low guttural sound that moved so quickly it broke through time. I felt ancient power, power inside of me that made me unstoppable."

Passive: Time Lord- Whenever Shike casts an ability, he gains a stack of [Time's Core]. For every stack of [Time's Core], Shike gains move speed and increased health regen. Cap of 4 stacks. Decays after 20 seconds.

Q: Living Time- Shike sends out a skill shot nuke, dealing 50/65/80/95/110 (+0.1 AP), and slowing the target by 10/15/20/25/30% for 1 second. If the target is already slowed, they are stunned for 1 second instead.

W: Broken Link- Shike warps through time itself, gaining 10/15/20/25/30% of his missing health back. (ie. If he has 100 health missing, and has this ability at level one, he gains 10 HP.)

E: Rush of Time- Passive: For every enemy around Shike, he passively gains an aura (range of Sunfire cape) that slows them by 5/6.5/8/9.5/11%. If Shike takes over 50% of his HP while a target is in this area, he stuns them.

R: Negative Energy- Consumes all [Time's Core] stacks. Explodes in a small radius (Radius of Ravenous Hydra), dealing 125/250/375(+0.2 AP), and slowing all targets hit by 15/20/25/30/35%. Every stack of {Time's Core] removed adds 50 damage and an extra 5% slow.
