One in Hole
Another comic loosely inspired by my homegame. In that it was a golem, which made it easier to lure into a large pit. But the idea of using a large mobile pit as enemy storage is pretty appealing. The catch is, we never found a way to get rid of it satisfactorily. So it’s still in there, and likely pissed off.
Also useful for another couple of things… like escaping on the Astral plane if you also own a bag of holding, encounter an old red dragon and are short on teleports.
