Gavin - The Guitarist of The Void

Okay, so I have the idea of making a new champ. This champ uses the power of his Cursed guitar's music to harm his opponents. I was hoping for him to be a Mage/support (Mid/support). Gavin's his name.

Lore - Gavin came from the quiet and small town of Kalamanda. His family being a poor family and having very little. But Gavin had one precious item. This was his guitar. Gavin saved up all the money he could scrounge from random jobs around town. He had his eye on this guitar ever since he was a kid. Even though the merchant had warned Gavin about the evilness locked inside the guitar because of the fact that it was curse, a curse from the Void. This void curse had killed the son of the merchant. Gavin had no belief in such a thing, and bought the guitar regardless of the curse. At first he felt nothing as he played it, but soon he felt the real magic start to pull him inside. It felt like pure darkness, as if the void had been in the guitar. Gavin fought it and won. Over many years he has tamed the curse, using it to his will. After Honing his new gift, he joined league. fighting in league was another childhood dream. Now Gavin is fighting just like in his childhood dreams. Skills

Passive: Stringy! - every 6 basic attacks Gavin's guitar powers up and the next string strummed adds an effect. string 1 - Gavins attack slows his target String 2 - Gavin wards the target String 3 - Gavin does an addition 50 magic damage for his next attack String 4 - Gavin's attack stuns the target String 5 - Gavin gains mana String 6 - Gavin gains health

Q - Shuri-pick: Gavin throws a magical guitar pick causing magic damage to anyone it passes through

W - Lullaby: Gavin plays a small melody that does magic damage and slows target

E - Sonic Boom: Gavin strums all strings as loud as he can causing the target (Ally or enemy) to be flung away or towards him. Deals magic damage(doesn't harm ally)

R - Possess: Gavin uses the dark magic of his guitar and charms the target causing them to waste any spells they have available, wasting their mana and damage to them. If Gavin targets himself then a enemy he uses their spells to heal him.

Well here is all his stuff. Please if you have ANY suggestions or if I forgot anything. thx for support.
