Barbed Ball

The spell generates a barbed sphere of flickering force that encloses only you. Smaller creatures or objects close to you when the spell is cast gets harmlessly pushed away, if something resists you are moved instead.

The sphere is weightless and floats on water and it's size is equal to your height plus 1 foot. You float in the center of the sphere and you don't have to move your legs for movement.

When inside the sphere you have resistance to bludgeoning damage, each creature makes its first attack roll against you at a disadvantage and when an opponent fails a melee attack it takes 2d6 piercing damage. You have disadvantage to all actions done after a movement.

You can spend all your movement to bounce against a creature in a straight line, if the target fails a Dexterity saving throw takes 2d6 piercing damage, after that you return where you started.

A Dispel Magic spell against the sphere doesn't suffer disadvantage. A Knock or Shatter spell deactivate the sphere for 1 minute. If a Disintegrate spell is cast on you the sphere is destroyed even if you succeed in the save throw, inflicting you 4d6 piercing damage. If you teleport, make a Charisma saving throw DC 15 to carry the sphere with you, if you fail the spell ends.
