Ahmara

Innate Spellcasting. Ahmara's spellcasting ability is Charisma (spell save DC 15). She can innately cast the following spells, requiring no material components:

At will: detect magic, longstrider

3/day each: misty step

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

Spider Climb. Ahmara's unearthly binding to the world allows her to defy the laws of earth. She has the ability to move up, down, and across vertical surfaces and upside down along ceilings, while leaving her hands free. Ahmara also gains a climbing speed equal to her walking speed.

Multiattack. Ahmara makes three attacks. Two claws attacks and one bite attack.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage.

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (2d6 + 2) slashing damage.

Shriek. (3/day) Magical Force Attack:  +7 to hit, reach 20 ft., cone. Hit: 7 (2d10 + 4) psychic damage. In savage frustration Ahmara let's out a guttural shriek from beyond the grave! All within a 20 ft. cone of Ahmara must make a Wisdom saving throw (DC 13) or be frightened.

Ghoulish Frenzy. In battle, Ahmara can throw herself into a vicious feeding frenzy. As a bonus action, she can make a special attack with her bite. If the attack hits, it deals its normal damage, and she gains temporary hit points (minimum of 1) equal to her Constitution modifier, and she can't use this trait again until she finishes a short or long rest.

Ghastly Speed. At the cost of a reaction, Ahmara can move seemingly teleport up to 30 ft. to an unoccupied space.
Counter Claw. Ahmara rolls a d8 to add to her AC, countering any melee attack with her own clawed hands. This also grants advantage on grappling the target or using a bonus action to make a melee strike.

Resurrectionist. Ahmara's undying curse encompasses her entire being. Should pieces of her remain after the length of a long rest, she returns whole and regains all of her hit dice.
