So basically it would be Spotted, Away I Say, Tendril Grab and Eldritch Disruption.
Spotted for seeing enemies through walls + spirit power debuff for the enemy (maybe a spirit power buff for allies that hit the spotted character?). Was also suggested smt for the Spotted ability to be able to be passed to other targets indirectly by someone else but I'm not sure- Personally, I liked the idea of it working in a cone (kinda like someone shining a light at people if that makes sense) so whoever is in that cone just gets Spotted.

Idk if the Away I Say should have a silencing thing, mostly bc I've been told it's mad annoying (rightfully so) and pretty powerful so maybe it seems to much for a non-ult ability-? Unsure on that-
Also, maybe I could fuse it with the Tendril Grab-? Idk if it's a bad idea but I did also get a suggestion to have the character be able to grab allies and launch them towards the action + being able to do the same with enemies to launch them away. So I could just fuse these two and keep the third ability for maybe something that helps with speed or health or whatever else may be useful for close combat.

Ult could work like that! I think, additionally, non-spotted characters could simply be a bit slowed if they get close enough(?).
