  • Amphibious. The screech leech can breathe air and water.
  • Swamp Camouflage. The screech leech has advantage on Dexterity (Stealth) checks made to hide in swampy terrain.


  • Blood Drain. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage, and the screech leech attaches to the target. While attached, the screech leech doesn’t attack. Instead, at the start of each of the screech leech’s turns, the target loses 5 (1d6 + 2) hit points due to blood loss. The screech leech can detach itself by spending 5 feet of its movement. It does so after it drains 15 hit points of blood from the target or the target dies. A creature, including the target, can use its action to detach the screech leech.
  • Screech (1/day). The leech screeches loudly. Each creature within 30 feet of the screech leech that can hear the screech must succeed on a DC 12 Constitution saving throw or be stunned until the end of the leech’s next turn.


Swimming in a swamp might not be the best idea. Especially when the screech leech is around. This blood-thirsty beast is always on the hunt in swamps, rivers, and lakes.

Born Sucker. These monsters feed on the blood of any creature they can find. Screech leeches can also send out a piercing cry to stun victims.

Armed to the Teeth. Gifted with razor sharp teeth, these beasts drain a large amount of blood in a short period of time. If one attaches itself to another creature the host is very aware of its presence. Finding one of these large leeches on one’s body is a very unpleasant experience.

Shocking Sounds. Some monster hunters say that the screech leech’s spooky call is worse than its bite. A few alchemists are reported to use these beasts to make healing potions.
