Shattering Weapon

Magic weapon (any that deals bludgeoning damage), rare (requires attunement)

This magic weapon deals an additional 1d6 force damage on a hit, or an additional 6 force damage to a nonmagical object.

Shatter Surface. In addition to its properties as a magic weapon, you can swing the weapon as an action at any surface, including a wall of force effect, and obliterate it as though you had struck it with the disintegrate spell. If you strike the ground, you create a cube-shaped pit 10 feet on a side centered on a point within your reach. Each creature on the surface where the pit appears must make a DC 15 Dexterity saving throw. On a failed save, the creature falls in (generally taking 1d6 bludgeoning damage from the fall); on a successful save, the creature can use a reaction to move up to its speed to a location off the pit before it appears. The pit’s edges are rough and easy to climb, requiring only a DC 10 Strength (Athletics) check. The Shatter Surface function can’t be used again until the next dawn.
