  • Mirror Walk. The bone spur can travel between reflective surfaces. This ability functions at will and is in all ways like the dimension door spell, except the bone spur must step into a reflective surface (mirror, polished shield, still pool, etc.) and emerge from another reflective surface within range. It can do this as part of its move action, with each mirror walk comprising 10 feet of total movement.


  • Multiattack. The bone spur makes two claw attacks.
  • Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d6+2) slashing damage. The bone spur appears much like a shattered bone. Its long, dirty, white torso consists of multiple layers of thick bonelike skin. It crawls upon four thin legs that protrude from its body, much like an insect. These legs end in scythelike apertures that make for poor feet, giving the beast a stilted gait when it walks. Its true form, however, is very different, for it is little more than reflected stain possessed of an intelligence that allows it to hunt. For this reason, the bone spur is only found in a reflective surface, a mirror, a highly polished shield, within a jewel, a piece of silver, and so on. Their reflection has no particular size, so their lair may be any item of any description.

    Creatures of Malice. They bone spur is a creature of utter malice, dwelling in the filth of their own evil. They are semi-intelligent, following simple directions with ease. They desire direction in all their actions, seeking some affirmation in almost any task they undertake. For this reason, they are often used as guardians by magi, evil paladins, and the like. Once set in a role, they remain there until destroyed.


The bone spur is an ancient creature, created as they were in the Void long ago. It is believed that the bone spur came to be when splinters of the All Father’s tools caught the reflection of his manifest thought. Being a reflection, the image of the thought turned, and the bone spur knew no goodness, but only evil. But because they stood in the presence of the All Father, they longed for his direction, something he never gave.

So, the bone spurs came to dwell in the deeps of the Void, even at the beginning of time. They are summoned from time to time, hunted, captured, and traded by those who are skilled in crossing the Wall of Worlds and able to plunder the wealth of the Void.

As guardians, they are unmatched for their fearsomeness and ability to follow simple commands.

Mirror World Ravagers. In combat, the bone spur rises upon its hind legs and falls upon its victims with its fore legs, slashing with the jagged ends. If they are in danger of losing a fight, they will mirror walk from the material world into a reflective surface.
