Disconcerting Leap. The blood maggot can jump up to half its Speed horizontally and half its Speed vertically. If it’s within 5 feet of a creature at the end of this movement, it may make a bite attack against that creature with advantage .


Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage. The blood maggot attaches to the target. Any creature can make a DC 11 Strength check to remove it. While attached, the blood maggot cannot attack other creatures.

Burrow. Once the blood maggot is attached, it attempts to burrow into the target, which makes a DC 11 Constitution saving throw , taking 4 (1d4 + 2) damage on a failure and half damage on a success.

A blood maggot can be removed with a successful piercing or slashing attack and takes damage equal to half the damage dealt to the host. If it is not removed within three rounds, the target is infected with a blood maggot infestation . If the target dies at any point in this process, it rises 1 minute later as a gorger zombie.


Commonly found in the mud and viscera of battlefields, blood maggots continually hunger. While they will feed on corpses if given no other alternative, they instinctively attack any living creature they can detect in an attempt to infest them. Perhaps hinting at the strange intelligence they develop later in life, blood maggots have an uncanny knack for preferentially targeting unarmored creatures most susceptible to their attacks. They are also relentless, capable of traversing many kinds of terrain to get at their victims.
