Azusur

Pack Tactics. The azusur has advantage on an attack roll against a creature if at least one of the azusur's allies is within 5 feet of the creature and the ally isn't incapacitated.

Multiattack. The azusur makes two attacks; one claw and one bite attack.

Claw. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4  (1d6 +1)  slashing damage.

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

Shadow Blend. While in dim light or darkness, the azusur becomes invisible along with anything it is wearing or carrying. The invisibility lasts until the azusur uses a bonus action to end it or until the shadow azusur, is in bright light, or is incapacitated.
