Super Boss Monster II: The Die is Cast

From BoardGameGeek:

The Dice Queen has arrived in Arcadia with her diceling minions, introducing an all-new mechanic to the hit dungeon-building card game: dice-powered rooms and effects! Playable as a standalone or a sequel, Super Boss Monster 2: The Die is Cast brings you more dungeon-drafting, minion-placing, hero-luring gameplay. But now you'll need to master the power of dice! When you build certain rooms, you'll roll the dice to power them up by placing the dice in your dungeon. You can then manipulate those values with other Rooms, abilities, and Spells! The Die is Cast and Super Boss Monster will never be the same! Super Boss Monster 2 is backward compatible with all existing Boss Monster and Super Boss Monster cards. As a standalone game, Super Boss Monster 2: The Die is Cast will contain everything that players need to play. -description from the publisher
