  • Amphibious. The giant leech can breathe air and water.
  • Swamp Stealth. When in a swamp, the leech makes stealth checks with advantage. Vulnerability to Salt. A handful of salt burns a giant leech, dealing 1d6 points of acid damage.


  • Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) piercing damage, 7 (2d6) poison damage, and the creature is grappled (escape DC 13). While grappled in this way, the leech doesn’t attack. Instead, at the start of each of the leech’s turns, the target loses 9 (1d6+2) hit points due to blood loss. A creature can spend their action carefully applying fire to the giant leech, causing it to end the grapple.
