Well if you do get back into it I wish you lots of fun! Demon wall is like 15ish percent of the way through the story not to mention the plethora of side quests, hunts, and completely optional areas with rad loot

Since you mentioned the demon wall you can skip the first encounter by just going through the door. The second encounter has like double the length of the hallway and half the health of the first

Just played through it for the first time last month. Definitely worth it. Feels really good to have gambits set up and just walk through an area and have the party just sweep through monsters
