[Champion Concept] Na'Zid: The Grasp of the Void

Alright I'm new here so hear me out, Void centipede.

Even better Void support. Eh? Right?

Ok. So before I get into actual numbers and what not I wanted to just explain what he is. When Aurelion Sol came out I noticed that he had a mechanic that no other champion had, a trailing body, meaning that his tail follows him around, see where I'm going with this? What if we could use that coding to create a Champion that actually uses a longer body that trails behind him? And what if it was considered a wall?

So a Void centipede with a long, segmented body that trails behind him, that's considered a wall. What about skillshots when he's side on, theres no way to dodge them really, so his passive is a bit of protection from this, his tail, while targetable and affected by skillshots, only take a portion of the damage and cannot be stunned, rooted, or snared, but can be knocked up, any targeted immobilization has to hit his main body/head for it to actually work.

So where does Grasp of the Void come into this? Cassiopeia was recently given a new debuff called grounded, which disallows any enemy with the debuff to not be able to use movement based abilities. My idea is that his E is a dash that knocks up people he E's through, either to the left or right of him, allowing him to split a group or knock someone towards (or away) from his adc/team. Now his W is the fun part, much like how Yasuo's ult only works on airborne enemies, his W grabs airborne enemies out of the air and slams them to the ground, causing a grounded debuff for a short while. This W can work with ANY ENEMY airborne, no matter the cause. Meaning Jax, Tristana, Kha'Zix who is a rival bug Void monster, Etc., will all have to be careful around him. Although it would have a relatively short range because it's primary purpose is to slam things he himself knocks up, so no jumping over The Wall. His Q is to flick the last segment of his tail onto enemies, much like how Nami's Q works, only one champion can get hit, and it latches onto enemies and deals a small amount of damage and grounds them for a short while, and that would be his main source of poke, albeit more for defense against incoming dashes. This makes for a good, fun feeling of snaking around the map, seeing an enemy, and beelining it to them, knocking them up, and launching yourself up to them to slam them back to the ground, much like a Vi ult, but less powerful and from a less powerful champion who needs other champions to back him up.

His ultimate splits his body into multiple segments and latches onto enemies, grounding them, and the only way to get them off is by an ally basic attacking you, or wait out the timer, which makes the enemies think twice about going alone into visionless territory. He would give up a portion of his HP for every enemy that he grasps, since it is his own body he's using, but his main head would sort of rise up and be untargetable for a few moments, to disallow himself from participating and continuously grounding and knocking up, along with his ultimate.

I feel as if this new Champion could bring forward new and interesting gameplay to The League, and also use the new grounded debuff in an effective and terrifying way, but its still a healthy way to get both teams to stick together when roaming, so that the enemy Na'Zid doesn't ground you while his team deletes you, and so you can be there when your ally Na'Zid ults a roaming champion. He is also great at zoning and protecting at the same time with his long body and stopping anything outside of a Malphite ult from getting past him. But he is also a huge target for skillshots when side on, and even with his passive protection he pretty much has to build tank and have good positioning, knowing where to block off and when to do it.

With that said here are some numbers:

Passive: Unflinching Tail Enemy attacks cannot immobilize Na'Zid's tail (Can be knocked up) and only do 50% pre-mitigated damage to him.

Q: Void's Reach Cooldown: 13/11/9/7/5 seconds Range: 750 Na'Zid launches a tail segment towards and enemy champion latching onto them, dealing x/x/x/x/x damage and grounding them for 1.5 seconds.

W: Prey Grasp Cooldown: 5 seconds Range: 300 around his body and tail Na'zid launches up to the nearest airborne enemy to the cursor and slams them back to the ground, dealing x/x/x/x/x damage and grounds them for 1.3/1.6/1.9/2.2/2.5 seconds.

E: Unstoppable March Cooldown: 21/18/15/12/9 seconds Na'Zid charges in the direction of the cursor, knocking up to either side of him any enemy in his path for 1 second and dealing x/x/x/x/x damage.

R: Grasp of The Void Cooldown: 150/120/100 Range: 900 Na'Zid channels and becomes untargetable for the next 6 seconds and splits his tail into 5 segments, which seek enemy champions within his channel range, when a segment latches on, it grounds the target for the rest of the channel or until an enemy champion basic attacks the segment off of them. The segments take 3 ranged attacks or 1 melee to knock off. Na'Zid loses 10% of his current HP for every segment knocked off, but keep any unused, or still attached segments HP.

I know the specific data may be clunky (especially the ult), and missing damage, and I ask for some help with those things, wording and damage tables. This is the first time I've ever seriously thought of a Champion concept and would love to hear any input you have.
