5e: "Do this when you get out": What are your healing rules?

[mahrundl]

Yes, I thought that it was an odd conclusion to draw too.

No need for anything as drastic as melting a hole - it's only 20' high and has sufficient protrusions to make climbing doable, if not exactly trivial. At least one character has already climbed it and seen what lies within.

Also, when I say 'iron', that is what it appears to be. The reality is not so simple. Your cauldron might find itself unable to even warm the wall...

It is soooo tempting to start a game at this point... Wall, cauldron - that's all you need!
