Rin, The Yordle Prodigy[Help would be appreciated]

Not original, I was looking at pictures of Rin the Yordle, by Rin the Yordle (Seen on all chat). I thought Rin should be a champion, so here are some ideas for her possible role/skills:

Background: Friends: Rivals: Probably already has a lore, but some ideas:

Rin grew up in Bandle City, and was considered very smart for her age. Some cruel kids would poke fun at her for being so smart, but she stayed upbeat and usually made them the laughingstocks. She came across a yordle named , who was a curious orphan that was also quite smart for his age, and quickly became friends. Rin showed great curiosity for technology and demonstrated it by creating all sorts of machines. One day, Rin's fascination and excellence in technology was noticed by a wise yordle inventor, . He wished for her to be his apprentice, but she was still to young. Heimerdinger decided to help Rin's education by encouragement and inviting her to his Yordle Academy in Piltover. Rin and Veigar graduated from Gustace's Senior Yordle Academy at a very young age, due to their prodigal knowledge and performance. Here, they parted ways, Veigar took up a job in a traveling caravan, and Rin went to Heimerdinger's Yordle Academy. Veigar accompanied Rin to Piltover, and said the last goodbyes. Little did Rin know that was the last time she would see Veigar as she knew him.

<She later graduated from Heimer's Yordle Academy and became his personal assistant. She worked part-time with Heimer for Piltover Customs, but also spent many hours developing magical and technological inventions, such as her famed Spyrit Wings.>(reworking this into off-client lore)

Role/Kit: Rin is primarily an ADC/Marksman, but can also be played as an APC/Mid Laner

Passive>Hextech Core: Every time Rin attacks, she charges up her Hextech Core, going from 0-6 stacks. Each stacks grants her 5/5/10/15% (Levels 1,6,12,18)Attack Speed and slows enemies by 30% when at 6 stacks. Stacks last for 3 seconds and cannot be refreshed. At 6 stacks, all stacks remain for 6 seconds.

Q>Pulsating Gauntlet: CD:6/5.5/5/5/4 Range: 950 Rin fires out a beam of energy from her gauntlet, dealing 40 / 60 / 80 / 100 / 120 (+ 100% AD) (+ 60% AP) damage. skillshot

W>Spyrit Wings: CD:17/16/15/14/13 Range: 500 Passive: Rin activates her Spyrit Wings, gaining 5/10/10/15/15%(+1% per 50 AP) movement speed. Active: Rin turbocharges her Spyrit Wings, phasing through the magical realm and dashing towards a target location, gaining 10/15/20/25/30%(+1% per 40 AP) movement speed for 4 seconds. (In flying form)

E> Projection: CD:18/17/16/15/14 Range:800 Rin punches forward, unleashing a projection of her fist in magical hextech energy. The first two enemies hit are dealt 30/40/60/80/100(+.6 AD)(+.45 AP) damage and knocked back 400 units and slowed by 30% for 1.5 seconds. If they hit terrain, they are instead stunned for 1.5 seconds.

R>Energy Barrage: CD:90/80/65 Range:800 Rin channels for .6 seconds to unleash a barrage of 6 hextech bullets made out of pure arcane energy from her wings, dealing 250/350/500(+.7 AP)(+.4 AD) damage in a 150 unit radius. The blast knocks enemies back 200 units, slowing them by 50% for 1 second or stunning them for 1.5 seconds if her hextech core is at 6 stacks.

Possible Quotes: Taunting Let's see how well you've taught me! :D Taunting Vei Vei! What... What happened to you?!! You wouldn't dare hurt... a girl.. would you? Forget that evil mumbo jumbo, redeem yourself Vei Vei! Taunting Let's put our technology.. to the test!

Interactions: when taunting Rin: You must embrace your inner evil Rin! when taunting Rin: YOU'RE THE SHORT ONE!

Appearance: Rin is standing up when attacking, but unfolds her wings and starts flying when moving. If Rin issued a movement command .6 seconds before attacking, she is flying while attacking. When Rin ults, she rises into the air and her wings angle, so that their tips point to the target. The bullets are shaped like the "feathers" of her wings and fire rapidly. The 6 bullets are only for a visual effect. I probably made Rin very broken, since I suck at balance and names.... like "Spyrit Wings" ;-;
