Crimsonwood 2

That's a really obscure situation. Something like that would be terrible. If the PQ was full of stages like that it would be a total failure. Waiting for specific classes to turn up so you can do the PQ is one of the worst things about a PQ.

Maybe get a better reward for the more rooms you clear seems plausible, though.

As for the paladin room, I always imagined it filled with monsters immune to most elements, but weak to one. Make it a room that resets when nobody's in, and that allows one person inside. Monsters you can attack only with Lightning, fire, ice, and holy... All four at the same time. Only one who can kill them all is a Palladin. Maybe make the holy one an extra so 3rd job ones can still clear it partially.

Gunslingers could still clear fire and ice, too...

Hermits, on the other hand, can be tricky. Imagine a box. It drops a potion you use when you loot it. And you haven't enough time to reach the end of the room to enter a portal with that transformation on... Solution? ALCHEMIST. With that skill, you get an extra 50% time to reach the door. Inside, make it a flash jump quest, and it'll be quite interesting overall.
