I mean, really. I'm dying to see that in action.
My friends did something similar. They defeated a lich but didn't know where its phylactery was. So they put the lich's corpse(?) into a bag of holding and poked a hole in it. If a sharp object pierces a bag of holding the bag ruptures and is ruined and all contents are lost forever. Take that lich!
