Special Traits

  • Chameleon. Whenever the reigon takes the Hide action, it has advantage on Dexterity (Stealth) checks as it uses psionic illusions to assist its attempt. Creatures with truesight automatically notice the reigon while it attempts to hide.
  • Keen Smell. The reigon has advantage on Wisdom (Perception) checks that rely on smell.


  • Multiattack. The reigon makes one bite attack, and two greatclub attacks or two claw attacks.
  • Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) piercing damage.
  • Claws. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 11 (2d6 + 4) slashing damage.
  • Greatclub. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.
  • Mindthrust (1/day). One creature the reigon can see within 60 feet of it must make a DC 13 Intelligence saving throw. On a failed saving throw, the target takes 25 (4d10 + 3) psychic damage, or half as much damage on a successful saving throw.
  • Concussion Blast (1/day). The reigon releases a blast of psionic force in a 15-foot cone. Creatures in the area must make a DC 13 Constitution saving throw. On a failed saving throw, the target takes 21 (4d8 + 3) force damage and is stunned until the end of their next turn. On a successful saving throw, the target takes half damage and is not stunned.


This powerful creature resembles a gorilla with thick, brownish-black fur. Its face is white and its eyes are brown. Its mouth is lined with rows of sharp teeth with the canines being slightly longer than the rest. Its hands end in wickedly sharp black nails.

A reigon is an aggressive predatory biped that dwells in dark forests away from general civilization, but not so far away that a small band of these creatures can’t go out hunting in the night hours. A reigon’s diet consists of berries, plants, forest game (both large and small), and sometimes humanoids (particularly if a supply, such as a small town or village, is readily available).

Reigons are tribal, territorial, and never associate with creatures outside their own tribe or family (including other reigons). If two reigon tribes move into the same area, a small war usually ensues with the victor claiming rights to the area and any survivors of the defeated side moving on to greener pastures. If a common threat presents itself, however, reigon tribes will band together in order to remove said threat before each tribe goes its own way.

A reigon tribe makes its home in thickly wooded areas usually well-hidden and out of the way, but fairly close to a natural source of water. Once seated, a tribe rarely moves, unless a new tribe moves into the area and forces them to flee or food and water become extremely scarce.

Reigon lairs are simple wooden structures covered with bark, cloth, leaves, and vines.

A reigon stands about 8 feet tall and weighs around 600 pounds. Its entire body, save for its face and palms are covered in thick fur. A reigon generally lives for about 40 years, with young reaching maturity around 4 to 6 years of age.

Reigons speak their own guttural language consisting of grunts, growls, and howls.

Reigons attack from ambush, using their chameleon psi-like ability to hide and wait for their targets to wander close by. Once in range, a reigon leaps to the attack, slashing and biting with its claws (though occasionally, a reigon employs a club). If an opponent isn’t killed immediately it is assaulted in the following rounds by a barrage of psi-like abilities, most notably a reigon’s mind thrust or concussion blast.

Slain prey is dragged or carried back to the reigon’s lair and either stored for later consumption or distributed among the other reigon’s in the lair.
