Unlight

You touch one object that is no larger than 10 feet in any dimension. Until the spell ends, the object casts shadow in a 20-foot radius and reduces to dim light for an additional 20 feet. The darkness does not continue around corners, and can be illuminated by magical light. Completely covering the object with something opaque blocks the shadow. The spell ends if you cast it again or dismiss it as an action.

If you choose an object you are holding or one that isn't being worn or carried, the darkness emanates from the object and moves with it. If you target an object held or worn by a hostile creature, that creature must succeed on a Dexterity saving throw to avoid the spell.
