Player: Mm-hmm. I'm okay.
DM: The jaws bite into you and you feel it rake across your shoulder, but you manage to pull out, roll on the ground to back up and you manage to get your arm up and pull yourself onto the platform where the orb is still glowing that dull green color.
Player: I'll turn around and fire my crossbow at the thing.
DM: Go for it.
Player: It's not great. It's only a 16.
