Though it is still dark, Ug can see the shining eyes of foes just outside the torchlight of the walls. As the first wave - orcs and goblins riding enormous wolves - advances, the goliath is glad that he decided to remain here. There is no way that the militia would last long against this force without his help.
The dire wolves easily leap the palisade walls, and the battle begins.
Ug should make 3 rounds' worth of attacks, and we'll see how we stand after that. Assume that a 13 hits, and just tally up the total damage dealt for attacks that hit.
