Special Traits

  • Amphibious. The frog spawn can breathe air and water.
  • Keen Smell. The frog spawn has advantage on Wisdom (Perception) checks that rely on smell.
  • Pack Tactics. The frog spawn has advantage on an attack roll against a creature if at least one of the frog spawn’s allies is within 5 feet of the creature and the ally isn’t incapacitated.
  • Standing Leap. The frog spawn’s long jump is up to 10 feet and its high jump is up to 5 feet, with or without a running start.
  • Swarm Traits. The frog spawn can occupy another creature’s space and vice versa.


  • Multiattack. The frog spawn makes two attacks: one with its bite and one with its tongue.
  • Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 4 (1d4 + 2) piercing damage. If the target is a creature, it must succeed on a DC 12 Constitution saving throw against disease or become poisoned until the disease is cured. Every 4 hours that elapse, the target must repeat the saving throw, reducing its hit point maximum by 5 (1d10) on a failure. The disease is cured on a success. The target dies if the disease reduces its hit point maximum to 0. This reduction to the target’s hit point maximum lasts until the disease is cured.
  • Tongue. Melee Weapon Attack: +4 to hit, reach 15 ft., one creature. Hit: 4 (1d4 + 2) slashing damage and 3 (1d6) poison damage.
