Faction unsure, but could see either FW or UD working. 25 nora Target opposing champion loses all AP, and becomes Immobile and Possessed for 1 turn.
I mean. 20 nora Target champion (friendly or enemy) becomes immobile and possessed for 1 turn. The idea would be that you could use it on enemy champions for stuff like using abilities attacks or satisfying 'friendly' targeting clauses while you could cast it on your own champ to essentially allow you satisfy 'enemy' targeting clauses. Example: Cast it on a unit produced from graveyard... attack it with a swarm unit.
Maybe a potential direction for replacement for Soul Corruption? With cliff diving going away, Immobile probably isn't necessary anymore, but does feel right thematically. Functionally, is this just a no damage stun?
Seems to be the case to me. Also I think Kalasle's idea was to synergise this with cull and other effects that benefit from 0 AP.
I don't think so. The duration is only 1 turn, so the champion is free to do as it wishes on its turn, and it becomes possessed so you couldn't attack it with cull. Seems like a cool rune, would allow you to use 0ap abilities, disengage for free etc. Not a huge range of uses, but could be incredible in some situations.
