Nil, Void Channeler

I feel like Riot forgot about the void, so I've come up with an idea for a new champion!

Base stats: Health, Regen, Attack Damage, Armor, Magic Resist, etc I have no idea because I don't know how to balance those out. Attack range: 600 Movement Speed: 325

Passive: Void Pressure When an enemy champion is hit by one of Nil's basic attacks or abilities, they gain a stack of Pressure, capped at 6 stacks. Stacks of Pressure last for 1 second. Stacks of pressure deal the following effects to enemy champions: 1 stack: 5% slow 2 stacks: 10% slow, takes 5% bonus damage 3 stacks: 15% slow, takes 10% bonus damage 4 stacks: 15% slow, takes 15% bonus damage. Upon gaining a fourth stack, is burned for 5% max health in true damage. 5 stacks: 20% slow, takes 15% bonus damage. Upon gaining a fifth stack, is burned for 10% max health in true damage. 6 stacks: 25% slow, takes 25% bonus damage. Upon gaining a sixth stack, grievous wounds are applied.

Q- Void Assault Cost: 60/70/80/90/100 mana Range: 750 Cooldown: 12/10/8/6/4 Nil fires a very thin stream of void energy in target direction, dealing 30/60/90/120/150 (+80% AP) (+80% AD) magic damage to all enemies it passes through. Can move while casting.

W- Void Beam Cost: 75/80/85/90/95 Range: 800 Cooldown: 14/13/12/11/10 Nil creates a massive beam in a cone 60 degrees wide that lasts for 2 seconds, dealing 10/20/30/40/50 (+60% AP) (+20% AD) magic damage per second. Nil cannot move or cast other spells while firing this beam, but can cancel the beam at any point.

E- Void Crest Cost: None Cooldown: 20/17/14/11/8 Nil gains 250/300/350/400/450 attack range on his next basic attack, and it deals an additional 0 (+50% AP) (+50% AD) magic damage.

R- Void Forsight Cost: 150/200/250 Range: 1500/3500/8000 Nil channels for 1 second, and creates a mark invisible to enemies. 2 seconds later, a massive beam with a radius of 75 units smites enemies standing on the mark for 300/400/500 (+120% AP) (+100% AD) magic damage.

This champion does not have a very complex kit, but my idea was to create a hybrid carry that is highly reliant on predicting where enemies will go, and highly reliant on positioning, but can also dish out massive amounts of damage.
