Devil's Sight. Magical darkness doesn’t impede the abishai’s darkvision.

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

Reckless. At the start of its turn, the abishai can gain advantage on all melee weapon attack rolls during that turn, but attack rolls against it have advantage until the start of its next turn.

Multiattack. The abishai makes two attacks: one with its bite and one with its claw.

Cold Breath (Recharge 5–6). The abishai exhales an icy blast in a 30-foot cone. Each creature in that area must make a DC 15 Constitution saving throw, taking 45 (10d8) cold damage on a failed save, or half as much damage on a successful one.

Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) slashing damage.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage plus 3 (1d6) cold damage.

Vicious Reprisal. In response to taking damage, the abishai makes a bite attack against a random creature within 5 feet of it. If no creature is within reach, the abishai moves up to half its speed toward an enemy it can see, without provoking opportunity attacks.
