"A
cloak of elvenkind is of a plain neutral gray which is indistinguishable from any sort of ordinary cloak of the same color. However, when it is worn, with the hood drawn up around he head, it enables the wearer to be nearly invisible, for the
cloak has chameleon-like powers. In the outdoors, the wearer of a
cloak of elvenkind is almost totally invisible in natural surroundings, nearly so in other settings. Note that the wearer is easily seen if violently or hastily moving, regardless of the surroundings."
