Void Support champ concept

I'll try to keep this rough for now. Was thinking ages ago that it'd be cool to have a full void comp with a true void support (not cheese support like Vel'Koz, or "void-adjacent" humans like Malzahar. Tried to think of how void grossness would tie in with the idea of helping your team-mates, and basically hit on the idea of a tanky parasite. The ult ability might be a little game/tech-wrecking, but I figure it could be doable in some form - the art might be the hardest part.

Jav'Yek, the Void Symbiote

Melee champ, survivable base stats.

Passive - Not sure, but probably something very simple since the rest of the kit is quite complicated. Maybe a passive boost to resistances around multiple enemy champs (Like the Legendary Guardian mastery?), or some kind of circumstance-based buff to hp regen?

Q - Feeding Tentacles/Viscera Burst -If unbonded or bonded with an ally, attaches two tentacles to nearby targets (prioritizing champs). This is undodgeable, but can be avoided/broken by quickly getting out of its range before it attaches, similar to Kled rope. Attached tentacles apply a slow for ~1.5 seconds, then damage for a %max health, healing Jav'Yek for a percentage of the damage. -If bonded with an enemy, simply does the life drain effect, with a bit of AoE damage as the target's viscera are ejected.

W - Adrenaline burst / Debilitating infection

• If unbonded or bonded with ally, gives a brief but intense boost to move speed, and next basic attack hits twice at some percentage of normal damage (starting at 60% and increasing by 5% per ability level?)
• bonded with enemy, gives a ~2 second debuff to attack speed and resistances? Maybe something more interesting or impactful, but I wouldn't want it to just be an unavoidable slow or stun.

E - Carapace growth / ? Unbonded or bonded with ally - create a shield. I'm thinking that to differentiate this from other shieldy supports it would be a relatively low-value shield which quickly regenerates over a period of time. So rather than a Janna or Lulu who can quickly react to block ~200-300 damage, JY could block ~40-70 damage per second, making his shield more effective against sustained damage but less so vs. burst. In addition, the shield restores a small amount of mana when it takes damage, which is shared with the ally if attached to a mana-using ally. Bonded with enemy - Not sure about this one. Maybe makes more sense if this is the resistance-debuff ability... or maybe a similar shield which protects parasite JY from damage while amplifying damage to the host? Not sure that's really interesting play though. Some sort of mana drain from host could be interesting, but I think there are issues with mana drain abilities in LoL. Other CC options could be cool, like a very brief but repeatable silence or fear effect. Maybe too annoying to play against.

**R - Profane Bond ** By now the gist of this should be pretty clear. Attaches to an allied or enemy champ at short range. Perhaps a very brief, surpressing channel when bonding with enemy, to allow their allies to interrupt with CC. When attached, JY has no control over movement and cannot attack. Right-clicking anywhere will cause JY to detach, maybe after a very brief delay. While attached, damage suffered by the target OR JY is split between the two. This means targeting gets weird if attached to an enemy champ, which is probably the biggest tech issue with this ability (along with the visuals). But basically, they can be targeted by attacks and abilities from either team. If bonded with an ally, JY takes a greater percentage of the damage, and this percentage increases with ability level. If bonded with an enemy, JY takes a smaller percentage of the damage, and this percentage decreases with ability level. Yes, as written this means that attaching to an enemy still technically shields them from your team's attack damage, but it also makes them vulnerable to AoE ability damage from their own team, and maybe the W or E abilities mitigate this unwanted shielding. I guess if a teammate kills their ally under these conditions, it counts as a kill for JY, or is treated as an execute? Not sure how towers would work, but I'm guessing Jav'Yek's towers would attack the bonded unit, but the victim's towers probably wouldn't. There's probably a better way of setting up these details, but we can imagine the basics working something like this.

Being able to absorb allies' damage forever, or attach to an enemy and spam unavoidable abilities is pretty oppressive, so: Being bonded to an ally drains mana over time at a moderate rate Being bonded to an enemy drains mana at a high rate, and abilities should take a pretty big chunk of the mana pool (Might actually want to use an energy system instead of mana if building mana items skews this too much). Essentially this means that you'd usually only be bonded with an enemy for 10-15 seconds max, and likely a lot less if you're using abilities actively.

Finally, there's just one more detail. Hitting R again uses up a large chunk of mana/energy, but allows control over the target for a few seconds, including movement and Autoattacks. The dream being to take over a fed ADC at a key teamfight moment and murdering their own squishies.

When unbonding, JY regains a significant percentage of the mana/energy used while attached. The idea is to limit the amount of time he can be actively attached, without necessarily removing him from action after the fact.

So that's it! What do you think? Overloaded? Unworkable due to technology or gameplay flaws? How do you think a symbiote support champ like this would affect the game? Would you be interested in playing a gross tentacle-shell-monster like this? Let me know, and please be kind.
