SPECIAL TRAITS

• Puddle Jump. Once on its turn, the swarm can use 10 feet of its movement to step magically through a body of water with its reach and emerge from a second body of water within 60 feet of the first, appearing in an unoccupied space within 5 feet of the second body of water. If the swarm is in a Huge or larger body of water, it can teleport to another location within the same body of water instead.
• Stench. Any creature that starts its turn within 5 feet of the swarm must succeed on a DC 12 Constitution saving throw or be poisoned until the start of its next turn. On a successful saving throw, the creature is immune to the swarm’s Stench for the next 24 hours.
• Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny elemental. The swarm can’t regain hp or gain temporary hp.

ACTIONS

• Bites. Melee Weapon Attack: +5 to hit, reach 0 ft., one creature in the swarm’s space. Hit: 14 (4d6) piercing damage plus 9 (2d8) poison damage, or 7 (2d6) piercing damage plus 4 (1d8) poison damage if the swarm has half its hp or fewer.
• Spit Swamp Sludge. Ranged Weapon Attack: +5 to hit, range 20/60 ft., one target. Hit: 18 (4d8) poison damage, or 9 (2d8) poison damage if the swarm has half its hp or fewer.
• Soggy Relocation (Recharge 5–6). While at least one creature is in the swarm’s space, the swarm uses Puddle Jump, attempting to pull one creature along for the ride. The target must succeed on a DC 13 Strength saving throw or be magically teleported along with the swarm to the swarm’s destination.
