Cardinal

Blackfire Weapons. Cardinal's weapon attacks are magical and deal an extra 22 (5d8) fire or necrotic damage on a hit (her choice, included in the attacks).

Legendary Resistance (3/Day). If Cardinal fails a saving throw, she can choose to succeed instead.

Magic Resistance. Cardinal has advantage on saving throws against spells and other magical effects.

Regeneration. Cardinal regains 20 hit points at the start of her turn. If she takes radiant damage, this trait doesn't function at the start of her next turn. Cardinal dies only if she starts her turn with 0 hit points and doesn't regenerate.

Sharpshooter. Attacking at long range doesn't impose disadvantage on Cardinal's ranged weapon attack rolls, and her ranged weapon attacks ignore half and three-quarters cover.
