Lylou put the ruby any sculpture pieces into a Magic Chest spell. At the same time, Finlay returned to the room with the columns to find that the wasps were agitated. He went down the side passage and was immediately pursued by giant ants.
Gideon and Chesley entered the column room and were attacked by wasps. The others came to their aid, but then a platoon of halflings appeared and attacked.
Finlay was wounded and near death twice, but was healed by Chesley. Lylou attacked from distance with magic missiles. It was a pitched battle and all the opponents were defeated, though more giant wasps hovered around the nest above.
