Uncanny Balance. Catherine has advantage on Dexterity saving throws made to not fall prone.

Myopia. Catherine has disadvantage on Wisdom (perception) and Intelligence (investigation) checks that rely on sight if the thing she's perceiving is more than 5 feet away from her and she isn't wearing corrective hyperopic glasses.

Introspective. Catherine has advantage on Intelligence (investigation) and Wisdom (insight) checks made to see through illusions.

Winded. If Catherine takes the dash action, then until the end of her next turn, she cannot make reactions, her movement is halved, and she can't dash or disengage.

Shapechanger. Catherine can use her action to polymorph into a Small or Medium human, or back into her true form. Without wings, she loses her flying speed.

Multiattack. Catriona makes 2 claw attacks and a headbutt/Ram attack in any order.

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

Claw (Human Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 2 (1d4) slashing damage.

Hickey. Melee Unarmed Attack: +5 to hit, reach 5 ft., 1 target. Hit: 10 (1d10 + 5) psychic damage. The target's hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. Catherine can choose to have the damage reduce the creature's hit point maximum to 1 instead 0. A faintly glowing magic bite mark is left behind that can only be seen by her and her target. The mark fades after 1d4 days.

Ram (Fiend Form Only). Melee Unarmed Attack: +3 to hit, reach 5 ft., 1 target. Hit: 3 (1d6) bludgeoning damage.

Charm. One humanoid the fiend can see within 30 feet of it must succeed on a DC 15 Wisdom saving throw or be magically charmed for 1 day. The charmed target obeys Catherine's verbal or telepathic commands. If the target suffers any harm or receives a suicidal command, it can repeat the saving throw, ending the effect on a success. If the target successfully saves against the effect, or if the effect on it ends, the target is immune to Catherine's Charm for the next 24 hours.

Catherine can have only one target charmed at a time. If she charms another creature, the effect on the previous target ends.

Mind-breaking Kiss. Catherine kisses an incapacitated humanoid. That creature is charmed by her until a until a remove curse spell is cast on it, the charmed condition is removed from it, or she uses this action again. The charmed creature obeys Catherine's verbal or telepathic commands.

She can communicate telepathically with the charmed creature as long as the two of them are on the same plane of existence. Additionally, while charmed in this way, a pink, aintly glowing womb tattoo appears on the crotch area of both Catherine and the charmed creature.

Etherealness. Catherine magically enters the Ethereal Plane from the Material Plane, or vice versa.

Frantic Retaliation. Catriona makes any combination of 3 hickey, claw, headbutt/ram or kick attacks against a creature grappling her.
