This long, curved knife has a blade of bronze and a large pommel of pure black onyx. It is razor sharp and very thin, designed for cutting skin from flesh.
In combat it functions as an ordinary dagger +2. It is only when it is used to skin a humanoid being that its special power comes into effect.
A skin cut by Bakak's knife can be worn by any humanoid of approximately similar size to the owner (for instance, a human can wear a human or elf skin, but not a dwarf's). Once a skin is worn it becomes a disguise so perfect that it is impossible to discern; the wearer looks exactly the same as the original possessor of the skin down to eye colour, height and weight. It cannot be discovered by a detect magic spell or similar. The only way the disguise can be noticed is by a small mark in the nape of the neck of the wearer, which looks like a tattoo in the shape of the knife itself.
A skin can be worn indefinitely, and removed at will. However, if it is worn for more than 24 hours at a stretch the wearer will find himself beginning to resemble the original possessor in more than appearance. After 24 hours, and for every subsequent 24 hour period thereafter, the wearer must taking a saving throw vs. magic. If he fails, his alignment permanently shifts to that of the original possessor of the skin.
