Anequina

I´m NOT a Yuan-Ti. Anequina is a Yuan-Ti, therefore she has resistance to poison damage and magic, which gives her advantage on saving throws against spells.

Pissy Attitude. Anequina seems like she´s always mad. Whenever she screams, she inately casts the Thaumaturgy cantrip, making her voice incredibly loud. This gives her advantage on intimidation checks.

It´s all about appearance and respect. Whenever Anequina is looking orderly (meaning she´s wearing her makeup, decent clothes, and has brushed her hair) she gains a +2 to her CHA modifier, and +1 to her prof bonus. However, if her hair gets messy, her clothes get dirty/ragged, or her makeup has worn off, Anequina looses confidence, and gains a -2 penalty to her attack bonus and spell save DC.

Blessing of the Devil King. Anequina is a respected cleric of Asmodeus. The fire of hell flows through her, empowering her fire spells. Anequina´s spells deal Hellfire damage, not Fire damage. This ignores all damage resistance to fire. Also, when Anequina deals fire damage, she rerolls all 1s she gets on her damage die.
