My six players are nearing the finale of Thirteen Cages. They've cleared out quite a bit of the dungeon (killed Gau, Freija, MoltenWing, Tiirok, Nulin, Ardeth, ...).
I'm planning to have the rest of the Cagewrights (Dyrryd, Shebeleth, Thearyn and some apprentices) make their last stand around the Tree of Shackled Souls. The players know there are still some Cagewrights in the complex, but they (especially the sorcerer) are getting low on spells. Now they're thinking about using the Wish from the Altar to Adimarchus to wish for 'a night's rest' or 'give the sorcerer back all his spells'.
I told them I'd think about it, but that I probably wouldn't grant it. To me it feels like it takes away all pressure and urgency there is. Did anyone else's players try this? What did you do? Would you grant it?
