Legend of Heroes: Trails to Azure - Part 22D: Old Mine Monster Extermination

The one extermination mission we have here sends us back to the dungeon where we reunited with Randy. Sadly, I do not remember my way through here, so I end up taking the long way through. I use the opportunity to farm some extra sepith as I go, but at this stage of the game, they just don't keep up.

As for the enemy, sadly these bats are so fat that you can't target all of them with your attacks, so you need to gradually chip away at them. If you're in good shape when the first drops, you usually have the match as you can turn it into a battle of attrition. I did this with barely any of the new gear from the chapter start, so you can grind up some money before coming if you want to make this easier.
