With a series of looping cartwheels and magic-enhanced flips, you move up to 30 feet in a straight line, your hands and feet spewing jets of flame. This movement does not provoke opportunity attacks. When you move within 5 feet of a creature, that creature must make a Dexterity saving throw, taking 4d6 fire damage on a failed saving throw or half as much damage on successful one. A creature can only be forced to make this saving throw once on each turn.
