A 6-foot-long beam of mountain stone springs forth from your hand with a massive boulderlike head. This functions as a maul that you are treated as proficient with. The mountain mallet scores a critical hit on a roll of 19 or 20 and when it scores a critical hit, you roll the damage dice three times instead of twice.
