How do you get Aranwen to raise the difficulty of the dungeon higher than 3? Or is that not meant to be possible?

The last main quest I did was unlocking the church. I then did a level 1 run through with all the cursed characters unlocked from it, saved, and shut the game off. Now I have no option to continue upon starting the game again.

Just getting into this and loving it so far. As a huge fan of Siralim Ultimate and Time Break Chronicles I'm disappointed I hadn't heard of this sooner. Some things aren't entirely clear as far as stats go for me, like I'm not entirely sure what agility is supposed to do. Is there something like an in game codex or manual or something that explains things more in depth?...

The Awoken Boss doesn't seem to get healed from his recovery stat. Not sure if this is intentional with the Arrogance passive, but it seems like he should get it since it's not from a party member. I see the number for the end of round heal pop up but his HP doesn't change....

Is that just damage without a specific element type?
