Aeon's End
Can Past and Future's content be used in one-off games, and how does true solo use upgraded basics?
Yes — skipping expeditions, you can use its mages, nemeses and market cards in one-off games with any core box. In true solo expeditions, only one upgraded basic goes in Tier 1 for battles 2 to 4; tiers 2 and 3 follow the upgraded basic table.
