Are you going stealth or frontal assault?
A high level wizards with a warlock or sorcerer could do it pretty easily. Cast Scrying to find out where the hostages are, then cast Teleport to them. Wizard casts Wall of Force in a 20x30 rectangle around the hostages while the other starts killing any enemies that are within. The Wizard then begins casting Teleportation Circle to escape with the hostages. Optimally, this should be done while a diversion force attacks the orcs, ready to withdraw shortly after the orcs engage. After a Long Rest, the spellcasters should be able to drop flaming death to clean up the orcs![]()
In a world where resurrection is a thing, I wonder if the hostages will be angry on you for first killing them by a meteor and then resurrecting them. Like, would they be ok with that?That's where the cleric with resurrection comes in!![]()
