[Champion Concept] Yusa, the Force of Shadows

Champion Design – Yusa, the Force of Shadows Lore: Tales tell of a shadow that slips through walls, eliminating the enemies of the Order of Shadows in the dead of night. The deadly enforcer Yusa, adopted and trained by the leader himself Zed, is said to be the Order’s secret weapon. Employing a special type of martial arts, Yusa weaves shadows into his blows, decimating his enemies, then slipping away into the darkness…

Passive: Touch of Shadow Yusa starts the game with no Attack damage and does not gain Attack Damage per level, and instead starts the game with 45 Ability Power, and his basic attacks deal (45 +20% AP) and deal Magic damage.

Q: Fists of Twilight Range: 450 Cooldown: 9/8/7/6/5 Yusa punches in a line moving forward slightly, dealing (30/45/60/75/90 + 60% AP) magic damage, and marks all targets hit with Dusk for 6 seconds. Basic attacks against units afflicted with Dusk deal an additional magic damage equal to (5/8/12/15/20%) of the targets current health and consumes the Debuff.

W: Force of Dusk Cooldown: 18/16/14/12/10 Passive: Yusa gains 5/10/15/20/25% Spellvamp. Active: Yusa’s basic attacks explode dealing (25/35/45/55/70 + 50% Bonus AP) Magic damage around him for 8 seconds. During this time every 4th basic attack will stun the target for (.5/.5/.75/.75/1)seconds.

E: Oblivion Shroud Range: 525 Cooldown: 19/17/15/13/11 Yusa dashes along target line slowing all enemies he comes into contact with for (15/20/30/50/70%) and gaining a shield that absorbs (75/100/125/150/200 + 30% AP *each enemy champion hit) for 2.5 seconds.

R: Shadow Rush Static Cooldown: 2/2/2 Yusa generates a charge of (Charge) every (25/20/15) seconds and can hold up to 2 charges. Active: Yusa gains stealth for 2 seconds and gains 25% Movement speed that decays over 3 seconds, during his stealth Yusa can move through terrain. If Yusa would end his stealth inside Terrain he is moved to the closes place outside it.

Playstyle: Yusa is a strong fighter, with solid mobility once he hits lvl 6. Yusa is designed with Top lane and Jungle in mind, with strong built in sustain with his W, he can sustain in both roles. With his E and active W, he can gank fairly well from the jungle, or set up ganks with his jungler as a top laner. Q gives both solid farming power and trading potential. Yusa is meant as a follow up engage, running in and diving onto priority targets and slowing them and stunning them to help his teams Assassins pick them off.

This is my first full champion concept, any constructive feed back is much appreciated :D
