Boss Rematch Hall

General Information
The Boss Rematch Hall is where you can fight previous bosses that you've faced during your journey, though, this only refers to story-related bosses (aka, bosses that you can't rematch without the Hall)

Also note that every boss that you face in the Rematch hall are at the same level that they were on when you last faced them (like Squelch still being level 5) also, once you beat a boss in a record of time, you'll get 1 Jewel for doing so.

How to obtain
You have to get the Mansion Parts from the red chest at the end of Cave of Darkness 3, and the Boss Rematch Hall will be automatically built.
