Workshop Wrecker

When this 3-inch-diameter metal ball is activated as a Magic action, it moves at a rapid speed, bouncing off walls and defying any attempts to capture it. The ball remains active for 1 minute or until you deactivate it by using a command word while within 30 feet of it (no action required). Once the ball is used, it can't be used again until the next dawn. When you activate the ball and at the beginning of each of your turns while the ball is active, each creature in the area makes a Dexterity saving throw, taking Bludgeoning damage on a failed save. The save DC and amount of damage dealt depend on the approximate size of the area in which the ball is active, as shown on the following table.
