As for the scrolls: either 2 GM up to level 3, or 1 up to level 5, as they wish. Otherwise, Barbarians with a Dungeon will be completely useless. They aren't particularly good here anyway. Let's say he captured a Dungeon, but he's already started building his GM up to level 2, so let him build another 2 GM up to level 3 tomorrow and use whatever he wants, or build up to level 5 in the Dungeon. It's up to him to decide.
