How the Mighty Fall
'I am the Bugbear Slayer!' says our wizard, with some measure of hubris.
Not that we entirely doubt this claim of a solo victory against the bugbear, particularly when we were all in the same combat, but the wizard's status of hero is a little shaken when, in the same round, two goblins stabbing at his calves cause the great slayer to drop to the ground unconscious.
