Diviner Wizard

The diviner makes three Arcane Burst attacks.

Melee or Ranged Spell Attack +7 to hit, reach 5 ft. or range 120 ft., one target. 20 (3d10 + 4) Radiant damage.

The diviner magically creates a burst of illumination in a 10-foot-radius sphere centered on a point within 120 feet of it. Each creature in that area must make a DC 15 Wisdom saving throw. On a failed save, a creature takes 45 (10d8) Psychic damage and is Stunned until the end of the diviner's next turn. On a successful save, the creature takes half as much damage and isn't Stunned.

When the diviner or a creature it can see makes an attack roll, a saving throw, or an ability check, the diviner rolls a d20 and chooses whether to use that roll in place of the d20 rolled for the attack roll, saving throw, or ability check.
