Champ Concept: Perax, The Rageblade's Forgotten Heir

This is pretty WIP, and is going to take a few iterations to complete. I am creating this champion concept primarily in honor of the soon to be removed Guinsoo's Rageblade (I hope you change your mind Riot), and as such am incorporating aspects of the item into his kit. (In other words don't say "unoriginal/boring" it is supposed to be similar.)

Role+Appearace: A Hybrid damage fighter who relies on fury and stacking passives to become stronger the longer he fights. He wields Guinsoo's Rageblade; a mythical Ionian weapon passed down through generations, its true power all but forgotten. He is very formal and solemn in appearance, but as he fights he becomes more and more violent/disheveled as the spirit within his sword takes control (in game, this would work so that he looks different based on how much fury he has).

Lore: To be added

Stats: To be added

Kit: Passive, Surge: When Perax falls below 50% health, he gains 20/30/40% AS and 5/10/15% lifesteal and spellvamp until he exits combat (7 seconds without taking or dealing damage). 120 second static cool down. Cool down begins once the effect ends, and is reduced by 1 second every time Perax basic attacks.

Q, Cry of the Forgotten: Active: Perax shouts in anger, damaging and slowing all nearby enemies (400 range) and applying a debuff called forgotten to all enemies hit. The forgotten debuff reduces the effects of all buffs (steroids, heals, speed boosts, Jungle buffs, etc.) by 25% for 4 seconds (does not effect lifesteal or regen, only activatable heals). If Perax has more than 50 fury, the debuff duration is doubled. Magic damage: 70/110/150/190/230 (+55% AP) (+40% Bonus AD). Slow: 20/25/30/35/40% for 3 seconds. 18/16/14/12/10 second cool down.

W, Rage's inheritance: Passive: Perax's basic attacks and spell casts grant him a stacking AS and AP buff for 8 seconds (2/3/4/5/6% AS, 2/3/4/5/6 AP, stacks up 8 times). Active: When Perax reaches max stacks, he can activate the ability to deal additional magic damage equal to (20% AP) with each of his basic attacks for 5 seconds. If cast when above 50 fury, consumes 50 fury to also gain 30% increased bonus armor and mr for the same duration. 9 second cool down.

E, Lost Tradition: Passive: When attacking an enemy marked with the "forgotten" debuff, Perax gains 20% crit chance for 3 seconds. Attacking a marked target again refreshes the buff. Active: Perax dives forward, flinging the first enemy champion he passes through behind him, dealing physical damage (dive range 800. Fling range 500 units back in the direction that he came from). Damage: 55/80/105/130/155 (+30% AP) (+60% Bonus AD). If cast when above 50 Fury, it consumes 50 fury and additionally knocks aside all enemies hit after the first enemy champion. 15 second cool down.

R, The Blade's Reckoning: Active: Perax releases the spirit of rage that dwells in his sword, dealing damage in an AOE (450 range) and gaining AP, AD, and Move speed as it empowers him. After 8 seconds, the spirit returns to his sword and heals him for 10% of his missing health (+1% per every ten fury he has, max 20% missing health total heal). Magic damage: 6/9/12% of Perax's max health. AP: (+10/15/20% AD). AD:(+5/10/15% AP). Move speed: 20/30/40. 120/105/90 second cool down. (NOTE: the bonus AD from his ult does not interact with the calculation for the AP, and vice versa.)

Animations: Idle: Perax holds his sword in his left hand and looks down its blade occasionally, but usually resting it on his left shoulder Passive: When his passive triggers, he glows slightly orange and every motion he makes leaves a short trail of orange/yellow, like the homegaurd trail, but more smokey. Q: Perax tips his head back, arms spread wide, and shouts. At the edge of the AOE, a small burst of yellow orange energy flares up, denoting where it has affected. Enemies are marked with a small stylized blade symbol to show if they have the forgotten debuff. If it is cast above 50 fury, the effects are red instead of orange/yellow. W: Every attack causes his sword to blur as the passive stacks, and when activated, he switches from holding it one handed with short precise swings to swinging two handed in harder more powerful hits. If cast when above 50 fury, he is surrounded on the ground by a small magical diagram as he moves, to show that he has gained an additional armor/mr buff. E: He dashes head first in a line, his blade held out in front of him. When he hits an enemy champion, he spins, flinging them over his shoulder with the barbed side of the rageblade. If cast above 50 fury, after he hits the first champion, he continues in the direction he was going, now spun around from the fling, shoulder checking aside every enemy he hits. R: Perax raises the Rageblade above his head and the spirit bursts forth in a flash of deep, almost black, red smokey tendrils. The tendrils persist around him until the spell ends, at which point they surge outwards and then reconverge back into him, changing to pale green on the way back in. Walking/running: Perax walks confidently, standing tall and proud with long strides, his blade resting on his shoulder. When running, he leans forwards and hold his blade down in both hands, pointed slightly behind him and to the left. Recall: Perax slashes around himself in a frenzy, creating a vortex of slash afterimages, before disappearing in them and returning to base. Death: Perax clutches his stomach as he dies, falling forwards and dropping the rageblade. His body turns into a red haze and is then absorbed into the blade, before the blade turns to a normal color again.

Still working on this, and feedback would be highly appreciated!
