Champion Concept: Avlayle, the priestess of the darkin tower shield.
Avlayle is an eternal, ethereal soul, bound to runeterra through the tower shield of darkin origin. The shield is giant and bulky, covering 4 directions with a shield for every direction. Avlayle is bound to that shield by a tether and she pulls it behind her, her being untargetable, being able to dash in by walking through a wall(untill the shield gets stuck) and do damage while her "body" a.k.a. the shield remains safe. Her true potential is unlocked when you bind her to an ally.
Passive(Darkin Curse): Avlayle binds with an ally by using the shield's curse.You share half of your current hp bar with an ally(the other half is like a pool) as a persisting shield that absorbs damage from the front, back, left and right. it disintegrates blocket projectiles, even whole ultimates if it absorbs them fully.you also share %armor and %mr with said ally. If the shield is destroyed you will break off of your ally with your remaining 50% hp. Q(Darkin Mirror/Protective dome): While unbinded your leash to the tower reflects all skillshots back at enemies, while binded transform the tower into a dome, immobilising an ally, making them immune to knockups, giving them bonus ar and mr and a shield scaling with max hp% scaling. That ally can use autos and skills while in this form. W(Whipleash/nether body): While unbinded you can hurl your shiled over walls and stun all hit enemies, when binded you can exit your host, remaining binded within the vicinity of your ally. your ranged auto attacks get extra range and they slow reseting upon hit. E(Sealing Curse): Available in nether form/ Get 3 stacks of "seal". Individual seals are small traps that silence enemies who get hit. But if you add another seal in the close proximity they form a wall. The wall blocks projectiles and silences all enemies within it. R(Backup Trick Seals): Distributes a backup seal globally to an ally, instantly granting them a shield, if you are binded you will be detached from your host and binding the chosen ally instead. you dart off to them similair to a really long range bard e. or you choose to grant the shield and open a way to your lane instead. The backup seal works both ways. so enemies and allies in the vicinity can use it for its duration.
It's a bit raw, since i can't test it or fill in the scalings and level ups. It's a basic concept so go easy on me lol.
