Their benefit is minor compared to most sets, the shield casts darkness on you the armor will slowly drain your health, the sacrificial mask will cast random spells in hopes to kill you, and the gloves will drain your health in exchange for power, the boots are the only things that don't hurt you but beware...when equipped the Death Walkers prevent you from running! After completing the snake-like widda location you will find a Widda Bow, the arrows are powerful and hard to find but should not be conserved...by the time you get the bow you are practically near the end of the game...use 'em up.
