  • Harmed by Running Water. The barguest takes 20 acid damage if it ends its turn in running water.
  • Keen Smell. The barguest has advantage on Wisdom (Perception) checks that rely on smell.
  • Magic Resistance. The barguest has advantage on saving throws against spells and other magical effects.
  • Master of Hounds. A canine that starts its turn within 30 feet of the barguest must make a DC 13 Wisdom saving throw, provided the barguest isn’t incapacitated. On a failed save, the canine is charmed by the barguest. A creature charmed in this way can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Once it succeeds on the saving throw, a creature is immune to this barguest’s Master of Hounds for 24 hours.


  • Multiattack. The barguest makes two attacks: one with its Bite and one with its Claws.
  • Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage. If the target is a creature other than an undead or a construct, it must succeed on a DC 13 Constitution saving throw or lose 5 (1d10) hit points at the start of each of its turns due to an infernal wound. Each time the barguest hits the wounded target with this attack, the damage dealt by the wound increases by 5 (1d10). Any creature can take an action to stanch the wound with a successful DC 12 Wisdom (Medicine) check. The wound also closes if the target receives magical healing.
  • Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage.


  • Change Shape. The barguest can polymorph into a goblin or a wolf, or back into its true form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.
  • Invisibility (Recharge 5-6). As a bonus action, the barguest magically turns invisible until its concentration ends (as if concentrating on a spell), it attacks, or it uses its Invisibility again. Any equipment the barguest wears or carries is invisible with it.


You see a monstrous black dog with large teeth and claws.

The barguest is a shapechanger, capable of assuming the form of a goblin, a wolf, or its true form, that of a large, fearsome goblinoid creature with bluish-gray skin.

When on the Prime Material Plane, barguests typically appear as large, shaggy black dogs with fiery orange eyes. They are omens of death and are said to herald a notable person’s passing by appearing followed by all the other dogs in the area, howling and barking. If anyone gets in the barguest’s way during this procession, it will strike out with its paw, leaving a wound that never heals.

Barguests are formidable hunters and trackers, skilled in both physical combat and spellcasting. They use their keen senses and shapechanging abilities to stalk and surprise their prey. In combat, barguests employ their claws and bite to attack. They are resistant to most forms of damage and have the ability to turn invisible at will, making them stealthy predators.

On Infernus, barguests are native to the Woe Wood of the Seventh Circle, where they roam free with their other canine brethren.
