Mastermind is a piece of enemy-exclusive equipment in the Dicey Dungeons Reunion that deals 10 damage when given a specific dice. The number of uses and the dice required change depending on the puzzle presented in the episode. It is the only way for the player to deal damage in this episode.

When the game reaches last puzzle once the boss is down to 10 or 20 health, it will take a combination of matching dice instead that deals the remaining amount of damage.

The equipment's name may be a reference to Mastermind, a code-breaking game which involves decoding a value based on the hints given.
