Yeah I kinda want to hold off on Irinlia for now in case they make a good path like how they say there will be a good path for Lace in future. On another note it feels weird that the hot spring event would lock out Naomi's sex scene as that felt like an optional or bonus scene. I didn't do the hot spring scene for her sister Shanna but I was able to get her sex scene later, so it seems unfair not to get it for Naomi.Irinlia I don't think has a good path. I got her by doing the murder mystery quest and solving the crime correctly using the guide. I would've gotten it wrong or confused if I didn't follow the guide on that one. if Irinlia has a good path I didn't take it.
Got to the Hellhound village on my second try. I ended up using the fights to recover my health while I wandered through the maze. I should have known since it was the only place I hadn't found AFAIK.
