New Champion Mechanics Idea

Note : I am basing this off a playable character in the game "Warframe" named Nidus.

So this "Nidus" has probably the most amazing kits in any video game i've ever played. His spells, abilities and passive all work generally the same as a league champion would, so i'll just name them as P - Q - W - E - R

P - Nidus' passive gives him 1 fifth of a stack for every enemy hit with a spell increasing his damage. (5 enemies hit = 1 stack, 99 stacks Maximum)

Q - Nidus sends out a shockwave dealing damage to everything in its path, for every enemie hit he regains x amount of energy (MANA).

W - Nidus sends out a void of infesestation in a target direction, pulling everything in its path to the center of the void. Basically an enhanced viktor W (pulling enemies to center) and it travels like a yasuo W but slowly and a much longer distance. Enemies inside the void can still attack and use spells though.

E - Nidus targets an ally or enemie and links with them. If Nidus targets an enemie, that enemie is stunned and a % of all damage Nidus takes in the duration gets transfered to that stunned enemie. If Nidus targets an ally, that ally deals extra damage based on nidus' stacks. NOTE : COSTS STACKS OF HIS PASSIVE

R - Nidus creates a circle around him of infestation, releasing infested "roaches" that seek out nearby enemies and latch on, doing DOT. After a certain amount of time, everything inside the circle is blasted with x amount of damage. NOTE : COSTS STACKS OF HIS PASSIVE

So as you can see, his kit synergizes AMAZINGLY well together. Of course the things i listed out are probably insanely OP in the world of LoL, but its just a suggestion to some kind of champion that stacks like nasus, but dealing extra damage with abilities and certain abilities cost the stacks you've accumulated. Al though the infestation is basically taken by zyra and malzahar, a champion with abilities like these doesn't necessarily need to be that type of theme. I'd really like to see a hyper carry duo, you could accumulate stacks and give it to your carry or something, but at an insanely high cost or risk.
