Qarin- The Parasite

Basic Lore: Yevarin, a young sorcerer came upon a sealed tomb while exploring Shurima. While searching the ruins he found an urn, with a still beating heart. He took the heart in his hands, and it stopped as he felt a sharp sting in his hand. Dropping the organ to spot a glance of a small white blur enter inside, he panicked. Surging his powers to try to expel the demon from his hand but could not find the power. He watched as it crept up his arm and took hold inside him, fading in and out of consciousness. As the parasite found control of the new vessel, he conjured up a name for himself. Qarin.

Passive: Host/Husk- This unit is host to a parasite that is still developing, upgrading skills will change the Husk's appearance/form/growths based on order learned.

Q: Dismember- Detach your own arm and throw it, passing through minions and latching onto the first Champion/Monster hit, dealing physical damage and stunning them for (x) second(s). Leveling Q first will cause the Husk to gain additional attack range and Physical Damage, P def scaling. Leveling second will cause slight attack range increase while only having Physical damage scaling.

W: Infectious Skin- (Active, AoE) A potent concoction spews from the Husk's pores dealing Magic damage every (x) seconds, leveling W first will cause the Husk to turn a Greenish hue and Grow in size, and have better HP, M def, HP regen scaling. Leveling second will cause slight discoloration and slight increase in size while having only M def scaling.

E: Resonate- Find the lost power from the life before, erupting magic energy in a cone in front of you, slowing enemies and dealing Magic damage. Leveling E first will cause blue energy to spew out from cracks in his skin and increase his passive speed, as well as Magic damage, Magic regen scaling. Leveling second will increase his Magic damage scaling only and shine light blue tones periodically around him while slightly increasing his out of combat speed.

R: Host Migration- The parasite leaves the Husk and infects the targeted enemy Champion, slowing the target immensely and dealing Magic damage every second for (x) seconds. While the Husk is without the Parasite it gains a decaying Speed boost but greatly decreases the Husk's Magic and Physical damage. Learning this skill completes the Husk's development and grants additional Magic damage scaling.

That's Qarin :D tell me what you think!
