  • Stank’s Revenge. Any piercing attack from the flank or rear has a 10% chance of popping the inflated anal gland of the piglet, releasing the noxious flatulence and causing the full effect as described under the mephitic gas action. Additionally, any piercing or slashing critical hit from the flank or rear has a 50% chance of popping the inflated anal gland and triggering the mephitic gas action, the mighty blow cutting deep into the piglet’s tender hide and puncturing the gas-filled gland. If stank’s revenge is activated, the piglet can no longer use the mephitic gas attack until able to heal for one week.


  • Bite. Melee Weapon Attack: +2 to hit. Hit: 3 (1d4) piercing damage.
  • Mephitic Gas (recharge 6). While making an attack, the stank hog lets forth a vile gust of air accumulated in its specialized anal gland. Roll 1d20. On a result of less than 10, the anal gland deflates and adheres to itself, rendering the mephitic gas for that stank hog unusable until it completes a long or short rest. A result of 10 or higher creates a five-foot-diameter gas cloud; 15 or higher creates a 10-foot-diameter gas cloud. The effect is immediate and profound, affecting all creatures within the cloud. Any creature that starts its turn within the gaseous cloud or enters the cloud on its turn must make a successful Constitution saving throw, the save DC equaling the stank hog’s roll, or become incapacitated. While incapacitated from the mephitic gas, the creature lies upon the ground with eyes stinging and vomit flowing. An incapacitated creature may make another saving throw at the start of its turn, ending the effect upon itself on a success. The mephitic gas lasts 1d4 + 1 rounds, lingering in the same area unless a strong wind disperses it. The stank hog is immune to its own and other stank hogs’ mephitic gas.


The stank hog is somewhat larger than its cousin, the common wild swine, reaching a shoulder height of 40 inches, a length of six feet, and weighing up to 500 pounds. Protruding from an elongated muzzle, a single set of curved and pointed tusks reaches a length of 10 to 12 inches upon maturity. Stank hogs are nearly devoid of fur, with only sparse, bristly hairs poking upward from their thick, dark-gray hides. Each of its feet has four toes that end in two larger frontal hooves and two smaller rear hooves. Its short tail ends with a tuft of bristly hair and twitches when the animal is agitated.
