Special Traits

  • Salt Vulnerability. The gutslug’s slimy skin makes it vulnerable to contact with salt. It takes 9 (2d8) necrotic damage each time it is hit with a cup or more of salt.


  • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage, and the target is grappled (escape DC 15). Until the grapple ends, the target is restrained.

Bonus Actions

  • Blood Drain. The gutslug can drain blood from any creature it has grappled, dealing 7 (3d4) necrotic damage.


These hideous creatures have many names-entrail worms, intestine crawlers, viscera worms, and several others. The most common name assigned to these leech-like parasites is gutslug.

Gutslugs are most often found in underground caverns, though some do lair above ground. Aboveground gutslugs build their nests in forested areas, often near lakes or rivers. They are never encountered in warm or cold regions as they detest both extremes. They are nocturnal hunters and generally avoid the sunlight if possible. (Sunlight does not damage them, they just don’t like it.) Subterranean gutslugs nest in crevasses, or in small caves or natural caverns, sometimes near a source of water. The lair is coated with a thick layer of slimy and sticky mucus (regurgitated by the gutslug). This mucus has a strong acidic stench and is easily detected at ranges of 30 feet or less. At irregular intervals (especially after feeding), the body of a gutslug widens to accommodate a bag-like stomach.

When a warm-blooded living creature is detected, a gutslug flies or crawls directly toward it, attacking and biting almost mindlessly.
