Bat King

No bats or werebats can willingly attack the Bat King. They can be forced to do so through magical means.

The Bat King has advantage on Wisdom (Perception) checks that rely on hearing.

If the Bat King fails a saving throw, he can choose to succeed instead.

3/DAY

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

The Bat King's weapon attacks are magical.

If he dies, the Bat King's soul reforms on the Astral Plane. In 1d6 days, it inhabits the body of another bat on the Material Plane which becomes the Bat King with all of the hp and abilities thereof. Only killing every bat on the Material Plane will prevent this trait from functioning.

The Bat King can use his action to polymorph into a Medium dark-skinned, bearded human man of slight stature, into a Medium bat-humanoid hybrid, or back into his true Small bat form. His statistics, other than his size, are the same in each form with the exception that only the Bat King's hybrid and bat forms retain his flying speed. Any equipment he is wearing or carrying transforms with him.

The Bat King can communicate with bats as if they shared a language.

The bat king's innate spellcasting ability is Charisma (spell save DC 16). It can innately cast the following spells, requiring no material components:

• At will: pass without trace, shatter, thunderwave
• 3/day each: darkness, scrying
• 2/day each: etherealness, freedom of movement
• 1/day each: astral projection, teleport

The Bat King makes two melee attacks.

Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 22 (5d6 + 5) piercing damage.

If the target is a humanoid, it must succeed on a DC 14 Constitution saving throw or be cursed with werebat lycanthropy.

Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 15 (4d4 + 5) bludgeoning damage.

The Bat King lets loose an ear-shattering screech in a 20-foot cone. Each creature in that area that can hear the screech must make a DC 18 Constitution saving throw.

On a failure, the creature takes 33 (6d10) thunder damage and is deafened for 1 minute. On a success, the creature takes half the thunder damage but isn't deafened. This attack deals double damage to objects and structures.

The called creatures arrive in 1d4 rounds, acting as allies of the Bat King and obeying his spoken commands. The creatures remain for 1 hour, until the Bat King dies, or until the Bat King dismisses them as a bonus action.
