You speed across the battlefield, releasing small bursts of magic at those you pass. Move up to twice your speed in a straight line. This movement ends early if you would pass through the space of a creature of your size, stopping your move in an unoccupied space within 5 feet of that creature. This movement doesn’t provoke opportunity attacks.    Each creature within 5 feet of a space you enter during this movement must make a Dexterity saving throw, taking 2d4 force damage on a failed save, or half as much damage on a successful one.
