Crimson Commander

Aura of Fear.

Any creature that starts its turn within 20 feet of the Commander must succeed on a DC 18 Wisdom saving throw or be Frightened for 1 minute. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Unyielding Will.

The Commander has advantage on saving throws against being charmed or frightened, and magic that would turn the Commander undead does not work.
