It is not known how many Bone Stitchers exist, but it is known to be only a very small number, less than a dozen at the most. Each looks like a giant spider, perched stop ten multi-jointed legs, with six smaller appendages dangling under the blood wet carapace. Eight gleaming crystal eyes glare at creation, four on the bottom of the carapace, and four located in the front, and the sides of the upper surface.

The Bone-Stitcher can do one thing, it can physically enhance any living creature with greater strength, endurance and agility, increasing any physical stat with ease. The catch is that very few creatures, or wizards, survive the augmentation with their sanity intact. For some, this is pointless as their sanity was gone long before they cast the spell to summon the monstrosity up from the hellish realms.

Once summoned, the Bone Stitcher pounces like a hunting spider, stabbing the summoner through the soft part of the abdomen with a six inch long stinger. The summoner is near instantly paralysed, and made largely numb to the pain they are about to go through. Using its dangling limbs, the Stitcher chops open the summoner and begins the process of augmentation.

The simulacra siphons blood from the summoner and uses it to creature synthetic muscle mass, spinning the tissue out of spider-glands on its own abdomen. With the small limbs it snips out the old muscle, devouring it, while spinning out new to take the old’s place. The summoner is subjected to the horror of watching their own bodies being pinioned open and eaten.

Stamina and endurance are increased in an equally disturbing manner. The Stitcher removes their bones, one at a time, and licks them clean before secreting a foul substance onto the bone, strengthening it. THe bone is then reinserted into the body while new muscle and tendons are spun out obscenely. The whole time, the Stitcher makes small clicking and gurgling sounds that sometimes sound like laughter.

One the augmentation is complete, the Stitcher then secrets tendrils of spiderfine silk and uses them to sew the savaged flesh back together. If bargained with, a stitcher can be induced to add very unnatural augmentations such as plates of bone under the skin, additional limbs, and the like. The summoner should have another victim on hand to provide the donor material, unless he is very foolish, and then he deserves to be eaten alive for bothering the Stitcher.

Limitations
Nothing touched by a Stitcher ever looks better. The cutting and sewing, while never life threatening, are vicious to the point of savage mutilation. Those enhance by the Stitcher are turned into Frankensteinian horrors of patchworks of their own skin.

It cannot make you smarter, if it eats the brain…the PC or NPC dies…permanently.
