  • Beast of Burden. The brag is considered to be a Large creature for the purpose of determining its carrying capacity.
  • Ethereal Sight. The brag can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.
  • Fey Ancestry. The fey has advantage on saving throws against being charmed, and magic can’t put it to sleep.
  • Incorporeal Movement. The brag can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.
  • Keen Hearing and Smell. The brag has advantage on Wisdom (Perception) checks that rely on hearing or smell.
  • Mimicry. The brag can mimic Beast sounds and Humanoid voices. A creature that hears the sounds can tell they are imitations only with a successful DC 13 Wisdom (Insight) check.
  • Sure-Footed. The brag has advantage on Strength and Dexterity saving throws made against effects that would knock it prone.


  • Bite (Mastiff Form Only). Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 4) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone.
  • Dagger (Humanoid or Brag Form Only). Melee or Ranged Weapon Attack: +6 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 6 (1d4 + 4) piercing damage.
  • Brag Buck (Cow, Horse, Mule, or Pony Form Only). Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage, and the target must succeed on a DC 14 Strength saving throw or fall prone.
  • Scare (1/Day). One creature of the brag s choice within 20 feet of it must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. The target can repeat the saving throw at the end of each of its turns, with disadvantage if the brag is within line of sight, ending the effect on itself on a success.
  • Etherealness. The brag enters the Ethereal Plane from the Material Plane, or vice versa. It is visible on the Material Plane while it is in the Border Ethereal, and vice versa, yet it can’t affect or be affected by anything on the other plane.


  • Change Shape. The brag can magically polymorph into a Large cow or riding horse; or Medium humanoid, mastiff, mule, or pony. Its statistics, other than its size, remain the same. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.
  • Mischievous Laughter. When the brag successfully uses its Brag Buck attack and causes a creature to fall prone, it can use a bonus action to emit a mischievous laughter, forcing all creatures within 10 feet to make a DC 14 Wisdom saving throw. On a failure, the creature is frightened until the end of the brag’s next turn.


The brag appears as a small humanoid with pointed ears and a wicked grin. When in animal or woman form, the brag looks deceptively real, seamlessly blending into its chosen disguise. However, keen observers might notice a hint of mischief in its eyes or an otherworldly glimmer.

The brag is a mischievous shapeshifting fey known for their trickster nature and their ability to change shape into various forms, such as a horse, donkey, dog, calf, pony, or even a woman. Some brags prefer to remain unseen, making terrifying noises during the night, while others take on visible forms to interact with humans.

Brags delight in causing havoc and confusion among unsuspecting humans. One of their favorite pranks is to offer rides on its back in its animal form before unceremoniously bucking them off into a nearby pond or bush and vanishing. Brags are known for their playfulness and love to laugh at the results of their tricks.

While most of a brag’s pranks are disconcerting but not dangerous, they can occasionally use their frightful laughter to further disorient their targets. The sounds of a brag in the night are enough to send shivers down the spines of those who have heard the tales.

Brags prefer areas where they can easily blend in with the surroundings or move unnoticed. Brags have been spotted near ponds, bushes, and wooded paths, where they can easily execute their pranks on unsuspecting travelers.
