Gems of Norcia is an optional expansion for Dig Down Dwarf. It adds a catch-up mechanic to the base game. If a player ends a turn without gaining a gem, they get to draw 3 random gems from the "Gems of Norcia!" pouch. Players gain 4 VP for every set of four different colored gems they draw from this bag over the course of the game. Contains 20 custom 12 sided gems in four different colors, a grey suede pouch, and instructions.
