Champion of the hunter -> skillchecks missing

[Shavul]

Hi everyone,

I'm currently kinda stuck on the "Champion of the Hunt" quest from the "Seeker, Slayer, Survivor" DLC. I finished the previous quest as the Seeker's chosen and, on first try, completed the quest by defeating Whehami, but this felt somewhat unsatisfying and I looked up if there's a peaceful way to end the conflict.

According to the game's wiki (https://pillarsofeternity.fandom.com/wiki/The_Champion_of_the_Hunt), it's supposedly possible to expose Aexica and convince Whehami to stand down through a serious of dialogue choices and skill checks. Problem is, not one of those checks (discover that all three faces share one soul with metaphysics 12 or that Aexica wants to leave with insight 17\18) is available for me, even though, as far as I can tell, my party has the required (combined) skills. I already reloaded an earlier save (before chosing which "face to become the champion of), but this didn't change anything.

My current party is skilled as follows (excluding skill not required for this quest):

Watcher: Diplomacy 20, insight 6
Aloth: Diplomacy 4, Insight 6, Metaphysics 11
Konstanten: Diplomacy 2, Insight 13, Metaphysics 2
Xoti: Diplomacy 2, Religion 13

Is this a bug? Am I doing something wrong? Or are any of those checks "watcher only"?

Thank you in advance.
