  • Amphibious. The guallipen can breathe air and water.
  • Malform. Creatures that end their turn within 10 feet of the guallipen must make a DC 14 Constitution saving throw. On a failure, their limbs are warped, causing their speed to be reduced to half. If the saving throw fails by 5 or more, their arms and hands are also warped, causing disadvantage on actions involving those limbs, including attack rolls. Creatures affected in this way can make another saving throw when they finish a long rest, ending the effect on a success. If an affected creature fails three times in a row, the change is permanent until removed with a lesser restoration or remove curse spell.


  • Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 11 (2d8 + 2) bludgeoning damage and 7 (2d6) poison damage.
  • Warp. The guallipen extends its warping power, choosing up to two creatures within 30 feet that are not more than 10 feet away from each other. Those creatures must make a DC 13 Constitution saving throw. Creatures that fail this saving throw take 12 (5d4) force damage and have their walking speed reduced to half until the end of their next turn. A creature has disadvantage on this saving throw if they are within 10 feet of the guallipen.


Guallipen (sometimes called huallepen) are odd near-beast monstrosities that appear like a sheep with a calf’s head. They can be quite stubborn and attach themselves to various herds in a vain attempt to fit in. Invariably, their warping aura causes them to be unwelcome by both herds and farmers.

Because they are such a nuisance, they are often targeted with bounties by villages that wish to be rid of them. Even though a guallipen is normally docile if unbothered, they fight ferociously if forced to leave an adopted herd.

Malformed Birth. Given enough time, a guallipen will eventually cause malformations to herd, eventually leading to the live birth of another guallipen. Once this happens, the original guallipen leaves the herd. The newborn guallipen then also leaves to start the process again in another herd.
