Tzuhi champ idea

Hi So yesterday i got this idea of a champ with a new kind of kit, it is probably messed up, and i wont talk scailing or basic stats.

Tzuhi The lone apprentice

I figured he could be a surviver from the noxus chemical attack on Ionia. He would have been a friend of trying to unlock the secrets of the wuju style. Then the attack from noxus hit Master yi tried to help Tzuhi. Confused and in pain Tzuhi was found by . Tzuhi and Tahm kench traveled through Valoran mastering the legendary wuju style, when he returned to Ionia, he found Master yi training with , blinded by rage he attacked. Unable to connect with the art of wuju, Tzuhi got defeated and retreated. Furious Tzuhi wandered through Valoran, when he in Shurima found a tomb, he entered and felt a call. Years past when Tzuhi appeared at the institute of war alone and destroyed, but stronger than ever.

Passiv: Tzuhi spawns with the item "loot of the god". "Loot of the lost son" can be upraded (1000g) to "Light of the west" granting 80 AP or "Darkness of the east" granting 50 AD. Q: cd 11/10/9/8/7. Mana: 60/65/70/75/80. light stance: Tzuhi fires light from his chest dealing 50/75/100/125/150 damage and stunning enemies for 1 second. cd 13/12/11/10/9. Mana: 70. shadow stance: Tzuhi places a shadow shield on an allied champion the shield can absorb 50/100/150/200/250 damage in 5 seconds. W: cd 11. Mana 60. light stance: Tzuhi heals an allied champion for 30/60/90/120/150 HP. cd 9/8/7/6/5. Mana: 50/55/60/65/70. shadow stance: Tzuhi dashes to the target dealing 70/125/180/235/290 damage silencing the target hit. E: cd 6/6/5/5/4. Mana: No cost. Tzuhi chances stance between light stance (500 range) and shadow stance (125 range). When Tzuhi is in light stance he gains 1%/2%/3%/4%/5% ability power until he changes stance. When Tzuhi is in shadow stance stance he gains 1%/2%/3%/4%/5% attack damadge until he changes stance. R: cd 150/120/90. Mana: 100/150/200. Tzuhi targets a champion, becoming a copy of the target, copying all stats and abilities (no cost) for 3/4/5 seconds. While "R" is active "Light of the west" will make Tzuhi take 25% less damage, and "Darkness of the east" will make Tzuhi deal 25% increased damage.

So this was the idea i hope you like it and give me some feedback and maybe i will share some other ideas
