Bolting Maneuver

You dash at lightning speed for a split second to allow yourself to escape a sticky situation.

You move up to half of your speed away from a creature within 5 feet of you that just hit you with an attack. This movement does not provoke opportunity attacks.

After moving this way, make a dexterity saving throw, the DC of which is equal to the number of feet moved + half the damage dealt to you. On a failed save, you fall prone.

The DC for the saving throw is decreased by 5 when you reach 5th level, 10 at 11th level, and 15 at 17th level.
