Champ Idea, Reidiss: The Abyssal Sentinel

Reidiss(raid-iss): the Abyssal Sentinel Role: Primary-Assassin Secondary:Fighter Health Base:530-1970(+80) Health Regen: 6.2-17.5(+.63) Basic Attack type: Melee Basic Attack Range: 125 Attack Damage:55(+3) Attack Speed: .655(+2.03%) Armor: 22.96(+3.25) Magic Resis:32(+1.4) Move Speed: 345

Background: Growing up in the Noxian capital, Reidiss learned early on, the strong survive and the weak perish. However, Reidiss was an especially gifted techmaturgist, creating a completely working power suit for himself by his seventh birthday. Shortly after his tenth birthday, he suddenly went missing. No one knew where he went. 15 years later, he returned stronger, faster, and corrupted by the Void. Through his techmaturgical gifts, he channels the powers of the Void and champions the submission of all Runeterra to the power of the Void.

Passive:Cascading Power-Passively gains an extra stack every 3 seconds. Gains a stack for every 2nd basic attack. Gains 5 points of abiliy power per 10 stacks. Stacks cap at 50 at level 1, 75 at level 3, 100 at level 6, 125 at level 9, 150 at level 12, 175 at level 15, 200 at 18. Once an ability has only 10 seconds left on cooldown, Reidiss can expend double the stacks to use the ability, this multiplies the next cooldown by 1.5.

Q:Into the Fray-cost:2/4/6/8/10 stacks(depending on level)-lob shot, jumps into target area, consuming up to 10 stacks of his passive. If he connects to an enemy champ, he roots both himself and the champ for .25 seconds per stack consumed (max 10), dealing damage=30/60/90/120/150+ Total stacks Cooldown:16/17/18/19/20

W:Eidetic Memory-passive, medium range, any enemy in the range for 3 seconds is marked for 1/2/3/4/5 seconds after leaving the field and gives vision to the team on affected champs. enemies in the field also take a 1%/2%/3%/4%/5% increased damage from stuns, roots, and slows.

E:Void Grenade-cost:10/11/12/13/14 stacks-lob shot, fires a grenade that temporarily manifests the void in the target area, dealing 5%AP(2.5% to minions and large monsters) over the duration of the effect and blinds for .5/1/1.5/2/2.5 (effects large creatures half as long)seconds in target area. If an enemy champ inside the rift uses cleanse, the field is dispersed and explodes, dealing 10/20/30/40/50+40% ability power in damage. Can be cast again before the blind ends to detonate rift, dealing 20/40/60/80/100 + 40% ability power in damage. Cooldown: 20/21/22/23/24

R:Enter the Void-cost:25/50/75 stacks-After a 1.5 second channel, Reidiss pulls himself and and one enemy into the void(can be cast on large monsters, minions and dragon. Can be cast on Baron Nashor, but you won't switch places). After 2 seconds, both he and his passenger return to our reality in each other's place, causing a small exploding rift, dealing damage=200/400/600+40% your bonus AP and 60% target's total AP to both allies and enemies(Reidiss's new location's rift deals to enemies and the enemies' rift deals to your allies) Timers on affected champs are paused, not cancelled. If a champion is killed while in the Void(ie ignited, Darius passive) when that champ would come back to the field, no damage is dealt to the opposing champs at the rift site. Cooldown:120/135/150

I will accept any critiques and comments about the champion, so long as they aren't insulting(ie "this is stupid").
