Oh Yeah
Hmm, okay, well you guys are right. Cinder didn't have any potions. In fact, Cinder, you don't really have anything except what you can get out of the new party treasure. Which means Brogg, all you did was bandage him at -3 and left yourself at 0.
No matter, just means that after saving Dave from falling, you dragged Cinder's body through the mirror and dumped it on the floor.
Anyway, nothing happens during your rest. Cinder, you're up to 0 hp, Brogg, up to 3, and Dave has 12 hp. You guys can change spells, Cure Light those Wounds, etc. Of course, it's still totally dark and cold and you have no idea where you are.
Cinder, you don't hear shit because you're actually unconscious all that time. Brogg, you have this crazy dream about a troll flying up on a hippogriff up this mountain. You're looking up at him wishing you had a hippogriff. He saves this princess and everyone around you cheers. Then under the weight, the hippogriff begins to buckle...
It is STILL dark and you are STILL likely to be eaten by a grue.
