Sire of Insanity

Any creature that starts its turn within 30 feet of the sire must make a DC 18 Wisdom saving throw. On a successful save, the creature is immune to this aura for the next 24 hours. On a failed save, the creature has disadvantage for 1 minute on Wisdom and Charisma checks and on Wisdom and Charisma saves. At the start of each of its turns, the sire can suppress this aura until the start of its next turn.

The sire has advantage on saving throws against spells and other magical effects.

The sire makes two attacks: one with its bite and one with its claws.
