This artefact will allow you to inscribe any bonecrusher weapons with one or several random otherworld magical symbols each of them imbuing the item with unique abilities. The higher the item’s quality, the more symbols you can inscribe upon it. There’s no way of telling which particular symbols will be inscribed—the magic of the Otherworld is unpredictable. If afterwards a similar cast is used on the same item, all the existing symbols will be substituted by new ones. Number of uses: 1.
