Shapechanger. The barghest can use it's action to polymorph into a Small goblin or back into it's true form. Other than it's size and speed, it's statistics the same in each form. Any equipment it is wearing of carrying isn't transformed. The barghest reverts to it's true form if it dies.
Fire Banishment. When the barghest starts it's turn engulfed in flames that are at least 10 feet high or wide, it must succeed on a DC 15 Charisma saving throw or be banished to Gehenna. Instantaneous bursts of flame (such a red dragon's breath or Fireball spell) don't have this effect on the barghest.
Keen Smell. The barghest has advantage on Wisdom (Perception) checks that rely on smell.
Innate Spellcasting. The barghest's innate spellcasting ability is Charisma (spell save DC 12). The barghest can innately cast the following spells, requiring no material components:
At Will: Levitate, Minor Illusion, Pass Without Trace. 1/day each: Charm Person, Dimension Door, Suggestion.
Soul Feeding. A barghest can feed on the corpse of a humanoid that it killed that has been dead for less than 10 minutes, devouring both flesh and soul in doing so. The feeding takes at least 1 minute, and it destroys the victim's body. The victim's soul is trapped in the barghest for 24 hours, after which time it is digested. If the barghest dies before the soul is digested, the soul is released. While a humanoid's soul as trapped in a barghest, any form of revival that could work has only a 50 percent chance of doing so, freeing the soul from the barghest if it is successful. Once a creature's soul is digested, however, no mortal magic can return that humanoid to life.

The barghest is one of the larger hellhounds, and sometimes called Bargtjest, Bo-guest, Bargest or Barguest, in the north east of what is starting to be called Angleland. It has huge teeth & claws, and sometimes referred to as a ghost or household elf. Legends state that it enters the city of York occasionally, to feed on lone travellers on Snickelsway. It is also tied in with town of Whitby, and Trollers Gill gorge. At least another two is found outside or near Darlington.
