Rahadin

Any creature within 10 feet of Rahadin that isn't protected by a mind blank spell hears in its mind the screams of the thousands of people Rahadin has killed. As a bonus action, Rahadin can force all creatures that can hear the screams to make a DC 16 Wisdom saving throw. Each creature takes 16 (3d10) psychic damage on a failed save, or half as much damage on a successful one.

Rahadin has advantage on saving throws against being charmed, and magic can't put him to sleep.

Rahadin can attempt to hide even when he is only lightly obscured by foliage, heavy rain, falling snow, mist, and other natural phenomena.

Rahadin attacks three times with his scimitar, or twice with his poisoned darts.

Melee Attack Roll: +10 to hit, reach 5 ft., one target. Hit: 9 (1d6 + 6) slashing damage.

Ranged Attack Roll: +10 to hit, range 20/60 ft., one target. Hit: 8 (1d4 + 6) piercing damage plus 5 (2d4) poison damage.

Rahadin's innate spellcasting ability is Intelligence. He can innately cast the following spells, requiring no components:

1/day: magic weapon, nondetection

3/day: misty step, phantom steed
