I completed the quest line to summon Eyedol, but I guess I went down the path that made it so that he was impossible to defeat? Thinking I screwed up, I started a new playthrough of the game to try and restart the quest, but neither it nor Eyedol are showing up anymore. Did anyone else have this problem?
I didn’t know it was possible to mess it up, I just picked randomly and I made it though fine. Eventually towards the end it took 3 or so turns of nothing before the final encounter but it worked.
You might be able to clear the eyedol story progress in the archive if it’s not showing up.
But yeah, it sounds like you just didn’t play the eyedol scenario all the way through. You’ve got to beat him into submission.
