Hmm... Actually didn't think about this, but that's an idea! Maybe a partial reset... On the other hand, it is a pretty long dungeon.
Enjoy the vacation!
Thanks! Could have an in-game timer, or something. If Brill does some measurable restocking, like buying stuff or crafting stuff or some recovery, then he gets the same amount of "time" to recover. And since he has a limit he can recover to, a.k.a the state he was at the beginning...
The player can try the gauntlet again but with more supplies if they want. Since with the current save system, people who face off against him the first time can just save, reload, and try try again if we think we have a good chance. And with a bad one, they can just leave to resupply.
