Manaless Semi-Carry Void Support

I'm putting the kit first for anyone who doesn't want to scroll past a wall of text before looking at the kit I have in mind. I'm calling the champion Pact Slasher for now as a temporary name. Also, I'm not using any defined values since I can't judge how this champion would fit into the balance of the game. Therefore, I'll hope that a Rioter sees this and would be willing to make it a reality. Enjoy.

I: Blight ||PASSIVE - Pact Slasher builds Blight with every basic attack (1 for minions and monsters, 2 for champions) which is used to cast his abilities. Blight can be stored up to 5, and for every stack of Blight, Pact Slasher gains bonus magic damage on-hit.

Q: Brand of the Void (Costs 2 Blight and [flat value] health, low cooldown) ||ACTIVE - Pact Slasher brands an enemy for a few seconds. The next basic attack from an allied champion will trigger the mark, dealing bonus true damage and healing Pact Slasher for a percentage of his maximum health.

W: Voracious Frenzy (Costs 3 Blight and [flat value] health, moderate-low cooldown) ||ACTIVE - Pact Slasher and a nearby allied champion gain attack speed and flat movement speed. Basic attacks by the ally affected by this ability heal Pact Slasher for a flat amount of health that increases the lower his health is. This heal value is reduced if the ally attacks minions.

E: Sacrificial Safeguard (Costs 4 Blight, sacrifice % of current health (as detailed below), moderate cooldown) ||ACTIVE - Pact Slasher sacrifices a percentage of his current health to shield an allied champion for the sacrificed health plus a flat value. When the shield ends, any damage the shield took is restored to Pact Slasher as health.

R: Parasitic Bond (No cost, moderate-high/high cooldown) ||ACTIVE - Pact Slasher forms a temporary bond with an allied champion. Both of them take reduced damage, and share any damage they do take. While this ability is active, Pact Slasher generates Blight over time.

Hi. I wanted to offer my idea for a unique support that fills a lot of holes in what is offered by the current selection of support champions. I watched a video a while ago by JeremyGC on Youtube about cool champion concepts to add to League of Legends, one of them being a manaless support. There is no manaless support that was intended to be a support, so I decided to try making my own.

One thing I realized about a manaless support is that you couldn't give them too much power of their own, or else they would have no obligation to being a support, thus defeating the point. I think it was about this point that I realized I could fill another hole in the support roster; a Void support. While many of the current Voidborn champions are capable of being a support, none of them are actually intended as a support. So while Vel'Koz was a popular support and although I once got carried by a Rek'Sai support, none of the void champions were actually meant as a support.

It kind of fit thematically too. The Voidborn offers power to the mortal, who in the process of accepting it, becomes Voidlike, sort of like being corrupted. I also knew that a manaless support would still need some kind of limiting factor, so I gave the champion their own resource, which here I've called Blight. I also attached health costs and health recoveries to the abilities to help encourage supportive gameplay. This ends up having the weird thing of the champion needing/wanting to build in three different ways at once (support, carry, and tank) but I think it could work out, especially considering the variety of items that are available in the game right now.

So it ends up that this would be a very unique support in several ways, because there is little about this concept champion that's quite like anything else. No other champion would play or itemize quite like this. Thank you for reading, and feel free to leave feedback in the poll and in the comments.
