“I would love it if you could take a look at the umber hulk,” a reader writes. “It’s such an interesting monster to fight against.” I don’t know whether I agree with that—certainly, from a dungeon master’s perspective, it’s not that interesting a monster to run—but maybe the experience is different from the player’s point of view.
