Amulet of the Dark

This amulet is shaped like a spider in a web.  There is an inscription on the back in Abyssal:

"Great Goddess, Mother of the Dark, grant me the blood of my enemies for drink and their living hearts for meat. Grant me the screams of their young for song, grant me the helplessness of their males for my satisfaction, grant me the wealth of their houses for my bed. By this unworthy sacrifice I honor you, Queen of Spiders, and beseech of you the strength to destroy my foes."

While wearing this amulet you have a layer of darkness over your whole body and don't suffer any effects from sunlight.

Once per day you can cast the spell Darkness.
