Cloak of Limited Invisibility

Up to three times a day this cloak grants Limited Invisibility, the 4th level Low Magic spell that makes only the wearer invisible, and only until he fights or casts a spell.

As a greater magic item its magic is permanent and renews itself each day. Making one calls for the materials of a minor magic item and two months plus two weeks for each level of the spell it holds, with a 99% chance of success; one offered for sale usually costs at least twice its materials plus 2,000 G.P. per week of enchanting. It counts toward the seven magic items a person may carry or wear at once; go past seven and none of them works.
