Dungeon Runs are semi-randomized crawls through a series of eight encounters (pulled from a list of 48) that players must beat using a starting deck and the choice of additional cards as you progress.
Mission Designer Dave Kosak sat down to talk with the community this week about the Dungeon Runs and the tasty treasure that awaits. Treasure cards are “blatantly overpowered” abilities that can only be used during these runs.
“Some of these treasures are bonkers by design,” Kosak said. “And some are bonkers by accident.”
