While trying to bring the spell to the game-play mechanic, idea popped up in my head. First, this "third" stance should be unavoidable, therefore not entirely in control of the player, just like there other two. To make it work in game, it has to be based on something to activate on. So these things come to mind:
 * stance should remove all cc and status effects and make him immune to them for a short duration
 * it could also fear all nearby enemies for a second or so
 * this acts like the third stance
 * basic spells while in this stance
 * cost no mana
 * have the same usage as Nach's part
 * has bonus effects or powers
 * do not share cooldowns with other stances
 * do not make him switch to other stance while in this stance
 * basic abilities gets new version of Nach's icons, just like Rengar's empowered abilities.
 * each basic ultimate-improved spell can only be cast once while duration holds, they do not start refreshing cooldowns, non-ultimate basic abilities become available after stance ends.
 * when stance activates, it gives maximum innate stacks, also while in stance his Q consumes these stacks to add like 9% percentage damage of enemy's missing health (like total 15% of missing health), something stack-based should be made for E too.
 * stance should activate when his health drops below danger level. For now, lets match it with Executioner mastery - below 40% health. Also, taking the lore seriously, Nach survived Shaco's joke and made out alive. It could be fit to make that the very damage, who brings Coronach below 40% hp can't kill him (feast, empowered ravage, dark matter, other high damage spells). If spell would kill him, it only brings him to 1 health, however any other damage beyond that point can be lethal.
 * ultimate could be a spell, available at level 1 and can be improved at 6, 11 and 16 (like Jayce's) for longer duration and maybe other bonuses.
 * recall the horrors could be first entirely passive ultimate ability, auto activating by Coronach's low health. Also this would make him first champion with 3 possible spells per key for every other stance.
 * duration should be reasonably short but still useful, something like 2 - 2.5 seconds at max rank.
 * considering that original Nach is a personality, entirely free from the Coronach's conciousness, it is so demented and insane with vengeance, that another unique and twisted thing can be done for his ultimate horrific recall:
 * when character enters the stance and fears nearby enemies, he also marks enemy champions with special mark that reveals them while in this stance, but he alone can see it. However, the price for that is his sanity and concern for his team, that Coronach is teamed up with, that's why player is left only with vision of his own (like an enemy Nocturne uses his Paranoia).
 * cooldown could be usual and not too often
 * or it could be really long (4-5 minutes), not affected by CDR, but it is refreshed by half total cd time, every time his team-mate dies in close proximity (between sight and 2000 range).

Many ideas written down for that Recall the Horrors spell. Not all of them are probably worth including. But I hope this helps to make an amazing twisted champion, that will really join the League.
