Incidental damage rules for the mastodon were spectacular as the beast breaks up the nearest goblins when smashing through the wall. Ivan the thief breaks apart from the main body, starts heading for the NW tower.
At the top of the map, goblins and cavewights (the latter more or less the equivalent of ogres in the Monster Manual - my ogres are tougher still), rushed out through the gate and over the top of the wall (the cavewights can simply rush up the stairs and drop beyond the wall). They were met by glaives set vs. charge, which made quite the mess of them. A single glaiver was able to roll triple damage, doubled for the set glaive, with a bonus of +1 from a bard's martial strains, for a total of 42 damage (maximum possible). Much celebration followed.
