Chillsby's Quantitative Quartering

You harness instantaneous quantum manipulation magic, allowing you to blast outward in a 30 ft radius, altering everyone's potential futures.

In response to a Saving throw of any kind, you can use your reaction to send out a wave of temporal energy, automatically allowing those within the radius to succeed on their saving throw.

If there is still damage on a success, everyone rolls the save. On a successful roll, the damage is halved again, to a total of one-quarter of the original damage.

If your roll fails, the save is still succeeded, with no additional effects.
