Weapon (maul), very rare (requires attunement)

This maul is covered with shards of stone surrounding a pair of giant horns. You gain a +1 bonus to attack and damage rolls made with this magic weapon. When you move at least 20 feet in a straight line toward a target and immediately hit it with a melee attack using this hammer, the target takes an extra 1d6 bludgeoning damage and must succeed on a DC 16 Strength saving throw or be knocked prone. If a creature is knocked prone in this way, you can immediately use a bonus action to make an additional attack with the hammer against the target. You don’t add your ability modifier to the damage of the bonus attack, unless that modifier is negative.

Trampling Charge. While holding the hammer, you can use an action to run forward in a straight line, up to 80 feet, without provoking opportunity attacks. While moving in this way, you can move through another creature's space, regardless of its size, and such a creature's space isn't considered difficult terrain for you. Each creature in that line must make a DC 16 Strength saving throw. On a failed save, a creature takes 3d12 bludgeoning damage and is thrown up to 10 feet away from you in a direction that is perpendicular to the line (you choose which direction) and lands prone. On a successful save, a creature takes no damage and moves up to 5 feet to an unoccupied space of its choice outside the line. A creature that chooses not to move or can't move makes the saving throw with disadvantage. Once this property of the hammer has been used, it can't be used again until the next dawn.

Do you choose to stand and fight, to resist the unstoppable? Or do you choose to run, with all the hope of fleeing an avalanche?

'Tis better to just lay down, and graciously gift your bones to the earth from whence they came.
