Silvered Quarterstaff

An alchemical process has bonded silver to this magic weapon. When you score a Critical Hit with it against a creature that is shape-shifted, the weapon deals one additional die of damage.

Topple (Mastery): If you hit a creature with this weapon, you can force the creature to make a Constitution saving throw (DC 8 plus the ability modifier used to make the attack roll and your Proficiency Bonus). On a failed save, the creature has the Prone condition.

Versatile: A Versatile weapon can be used with one or two hands. A damage value in parentheses appears with the property. The weapon deals that damage when used with two hands to make a melee attack.
