Baobhan Sith

Fey Ancestry. The baobhan sith has advantage on saving throws against being charmed, and magic can’t put the baobhan sith to sleep.

Innate Spellcasting. The baobhan sith’s innate spellcasting ability is Charisma (spell save DC 14). The baobhan sith can innately cast the following spells, requiring no material components:

At will: detect thoughts
1/day each:mass suggestion
3/day each:entangle,suggestion

Blood drain. If a baobhan sith charms a target creature with its captivating dance and is then able to bite the charmed creature (ending the charm), or if the sith is able to bite a creature and claw it in the same round, the sith can as a bonus action drain blood from this victim, dealing it an additional 5 (1d4+3) hit points of damage due to blood loss.

Captivating Dance. When a baobhan sith dances, all living creatures within 30 feet that view the rhythmic swaying and movements of its body must succeed on a DC 19 Charisma save or become charmed (a creature that makes its save cannot be affected by that baobhan sith’s captivating dance for one day). A captivated creature cannot attack the baobhan sith or target the baobhan sith with harmful abilities or magical effects, and the sith has the advantage on any ability check while socially interacting with the charmed creature. These effects continue for as long as the baobhan sith dances. A baobhan sith can move and act normally (including using her innate spellcasting) while maintaining her dance, and can pick up and carry items, but a bound, entangled, grappled, prone, pinned, or directly engaged in melee combat sith cannot begin or maintain a captivating dance. Whether or not a baobhan sith is clad or unclad makes no difference to the effectiveness of its captivating dance.

Dying Words. When a baobhan sith is slain, a curse is instantly enacted upon its killer (usually the baobhan sith hisses out a curse, but there need not be vocalization or even consciousness and intent, for this ability to function; it can only not function if the target creature successfully saves (DC 19 Charisma save) or the sith wills the curse not to come. Otherwise, the killer suffers a bestow curse that lasts for 1d4 days per hp the sith had (at its healthy maximum), and this curse lowers the killer’s highest ability score by 6 points.

Multiattack. The baobhan sith makes three attacks: a bite and two claws. Its bite can become a blood drain under the right circumstances. A baobhan sith customarily confronts possible foes with its captivating dance, and then entangles creatures that fail to succumb. If overwhelmed or outnumbered, a baobhan sith uses entangle and/or mass suggestion to aid it in fleeing.

Bite. Melee Attack: +5 to hit, 5 ft. reach, 1 target.
Hit: 5 (1d4+3) piercing damage.

Claw. Melee Attack: +5 to hit, 5 ft. reach, 1 target.
Hit: 6 (1d6+3) slashing damage.
