Special Traits

  • Vulnerability to Salt. A handful of salt burns a giant leech as if it were a flask of acid, causing 1d6 acid damage per use.


  • Blood Drain. Melee Weapon Attack: +3 to hit, reach 5 ft. one creature. Hit: 4 (1d6 + 1) piercing damage, and the leech attaches to the target. While attached, the leech doesn’t attack. Instead, at the start of the leech’s turns, the target loses 5 (1d8 + 1) hit points due to blood loss. The leech can detach itself by spending 5 feet of its movement. It does so after it drains 25 hit points of blood from the target or the target dies. A creature, including the target, can use its action to make a DC 10 Strength check to rip the leech off and make it detach.


These invertebrate parasitic relatives of the worm lurk in stagnant or slow-moving water, waiting for a suitable host. Giant leeches appear as larger versions of the common leech.

A giant leech attacks any living creature that comes within 30 feet of it.
