Traits

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.

Actions

Multiattack. The abishai makes one Bite attack, one Claw attack, and one Longsword attack.

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

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

Longsword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:7 (1d8 + 3) force damage, or 8 (1d10 + 3) force damage if used with two hands.

Reactions

Vicious Reprisal. In response to taking damage, the abishai makes one 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.

Lore

Each abishai was once a mortal who somehow won Tiamat's favor before death and, as a reward, found its soul transformed into a draconic devil to serve at her pleasure in the Nine Hells. Each type of abishai is associated with one of Tiamat's five dragon heads: black, blue, green, red, and white.
