The night's jambiya spell cloaks a single jambiya in impenetrable shadow. The weapon is concealed from view, though the darkened area is easily visible. When thrown, the dagger is nearly impossible to dodge, providing a +3 attack roll bonus. Once the spell is cast, the jambiya can be handed to another character to throw, but that character must throw it immediately in the next round or the magic is lost. The night's jambiya gives no benefit in melee. The spell requires a jambiya, which is not consumed in the casting.
Notes: Common for spellcasters from an Arabian setting; otherwise very rare.
