Cloak of elvenkind

A Cloak of Elvenkind is an ordinary-looking cloak, often gray in color, sized to fit an elf (although there are a tiny number of cloaks to fit halflings or dwarves). When the hood is drawn over the wearer's head, it grants near invisibility.

A cloak of elvenkind radiates faint Illusion magic.

This cloak also appears in Baldur's Gate II: Shadows of Amn (game), in which this item can be gained when visiting Suldanessellar.

Creation
The creator of a cloak of Elvenkind must be an elf and know the spell Invisibility.
