Shadowmeld Blade

A greatsword known to be made by Uthem Grunaga, as its distinct design of flesh like blade and bone handle, this item seems to glow with darkness as the sword itself when sheathed grants a +10 to move silently checks. However, when unsheathed granting a -10 to hide checks as the blades origin seems to steep itself in the hatred for its user. Like many of its kind, it is now marked as part of the Shadowbane Arsenal, a collection of items purely made of gloom parts.
This item is treated as a +1 greatsword that increases your move silently by +10 when sheathed, and -10 to hide checks when unsheathed.
