Disk of Repulsion

As a bonus action, you may break the disk, which destroys it, unleashing a wave of repulsion energy.

Each creature and object within 10 feet of you is pushed 15 feet directly away from you. Creatures that succeed on a DC 13 Strength saving throw avoid this effect.

You may use your reaction to break the disk if you are targeted by an attack roll, which causes the attack to miss in addition to the disk's other effect.
