Keen Hearing and Smell. The chupacabra has advantage on Wisdom (Perception) checks that rely on hearing or smell.
Pack Tactics. The chupacabra has advantage on attack rolls against a creature if at least one of the chupacabra's allies is within 5 feet of the creature and the ally isn't incapacitated.
Multiattack. The chupacabra makes two attacks: one with it's bite and one with it's blood drain.
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 2) piercing damage. If the target is a creature, it must succeed on a DC 11 Strength saving throw or be knocked prone.
Blood Drain. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 5 (1d4 + 3) piercing damage, and the chupacabra attaches to the target. While attached, the chupacabra doesn't attack. Instead, at the start of each of the chupacabra's turns, the target loses 5 (1d4 + 3) hit points due to blood loss.
The chupacabra can detach itself by spending 5 feet of its movement. It does so after it drains 10 hit points of blood from the target or the target dies. A creature, including the target, can use its action to detach the stirge.
