Eiyuden Chronicle: Hundred Heroes - Part 37: Castle Harganthia

I kind of got a Super Mario RPG vibe here in that like Bowser, Markus got evicted from his castle and needs our help in getting it back...

Otherwise, Marisa strikes out in order to avenge her home and it is a bit of a lengthy segment. The important thing here is that we need to get Sacred Tree Chips as we need to use these to expand Gocteau's operation back at our castle. In doing so, we will have access to all of the resources in the game and can completely upgrade the castle. If you do not get the chips here, you will need to come back for them later, and you will lose out on some time. As a result, you will need to burn some game time doing things while the teams are out gathering resources.

Otherwise for this part, the castle is one of the better dungeons in the game I think. It doesn't abuse the vertical element and may even give a bit of Castlevania vibes to people. If you bring both necromancers, you do get a damage boost to undead enemies, so that can allow you to cut through the random battles a bit more quickly, meaning that the fights are even less of a slog. That may have played a part in building a smoother experience.
