Witch Time

When a creature within 5 ft. makes an attack against you you can use your reaction to make a dex saving throw plus your proficiency modifier against the creature's Athletics check. Should your save be successful you easily avoid the attack and you interrupt the creature's turn as you can now either choose to attack or move and once you've made your move the creature can finish it's turn. On a failed save you take double damage.

Attack: If you choose to attack you have 1 bonus action to make. Once you've made you attack you end your mini turn letting the creature finish it's turn you interrupted.

Move: If you choose to move you can either make a dashing action or move you full movement speed. The creature can't take an attack of opportunity on you when you do this.
