Radiant Retibution

When your hit points fall below half your maximum, the Angelic Boon flares with divine energy.

For 1 minute, your weapon attacks deal an additional +1d4 radiant damage.

Each creature of your choice within 10 feet must make a DC 13 Constitution saving throw or be blinded until the end of its next turn.

Once this feature activates, it cannot be used again until you finish a long rest.
