Champion concept: Shapeshifter

Just something i thought about havent got a name yet.

But i think it would be cool to have a champion who can shapeshift into usefull objects or things or even other champions(clone like). Its main scaling stats would be health and mana and cooldown. and it would be a supportive champion with many unique uses. This champion would be very flexible in use and provide alot of utility for the team.

Ability 1 shapeshift into structure ** use 1** You shapeshift into a wall, during which the champion cant move and for all intents and purposes is a wall. ally abilities can pass through but it intercepts enemy abilities taking damage(braumstyle) while in wallform you would get damage reduction. bot enemies and allies can use the wall to stun people like poppy for example could stun your ally into you if you are in wall form.

Use2 When cast on an already existing wall you would turn into a portal (kind of like bards journey) it would only work on small/medium thick walls allies who pass through get a small speedboost. enemies can also pass through.

turning into a portal makes you untargetable but also makes you unable to deactivate immediately, you have to wait a 1 or 2 seconds. Also when you deactivet you get to pick which side of the wall you return to.

Use 3 when used on a fallen turret, you channel very shortly then turn into a tower, you inherit the towers properties for the duration, you have its range vision/true vision and its attacks. So you are pretty much become the turret that used to be there.(works kind of like azir turret) You do keep your own health armor/mr and aura's from items. So its not as strong early on.

This would be a toggle ability which cost mana(depending on what use) for upkeep and initial cost. with a moderate cooldown

ability 4 Its ultimate would allow this champion to shapeshift into any champion in play. Completely cloning their abilities, and their costs and passive ability. manacost depends on the level of the champion you shapeshift into. Then it drains a flat amount of your mana untill you are oom upon which you shift back refunding a % of your mana.

Would use its own main stats for scaling, cdr would be used for bonus attackspeed/crit if the champion you shapeshifted into has more attackspeed/crit then you do. You would gain ad/ap depending on bonus mana if the champion has more ad/ap then you do obviously this ratio would be balanced out. But you will never gain more ap/ad and or attackspeed/crit then the cloned champion. You do however gain some flat penetration for the duration depending on bonus health, but within reason.

What is next? Well so far thats it, i think the ult needs some more detail, havent gotten to defensive stats yet. And ive only got 1 other ability so far with 3 uses, which although not 100% unique are still quite different from where i took inspiration from.

Still going to need to do a few things like come up with the other 2 abilities and the passive, and add a description of the champion who he is where he come from lore & stuff

feel free to post idea's for lore & abilities or give feedback on what ive got so far.
