Beggar Ghoul

Hungry Dead Nature. The ghoul requires no air or sleep.

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

Savage Hunger. Its Bite attack is a critical hit if the beggar ghoul bites a creature it has surprised.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) piercing damage.

Claws. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 2) slashing damage. If the target is a creature other than an elf or Undead, it must succeed on a DC 10 Constitution saving throw or be paralyzed for 1 minute. A paralyzed target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
