The dungeon that immediately comes to my mind is Wanderer's Palace. I feel like that dungeon could be SO COOL -- if the Tonberry Stalkers actually represented a threat. I'd have a single Stalker pursuing you, moving significantly faster, and have him 1-shot anyone he reaches.

In fact, it would be even cooler if part of the dungeon REQUIRED someone to "bait" the stalker, effectively buying the rest of the group time to unlock the next area, while the "bait" is effectively a sacrificial lamb (or maybe they have to pull a lever the same time at the rest of the group?).

To my knowledge, there is no instance in the game which REQUIRES a player to die, and it just seems like it would be a fun way to shake things up, and REALLY amp-up the pressure!

I'd also love a remix of Haukke Manor (maybe said revamp could also be used for Halloween?)!
