Twilight Torch

You touch one object that is no larger than 10 feet in any dimension. Until the spell ends, the object casts a 15-foot radius shadow where bright light becomes dim, dim light becomes darkness for the duration. Completely covering the object with something opaque blocks the shadow. Creatures with darkvision can see normally in the darkness created by this spell, but non-magical light cannot  illuminate it. The spell ends if you cast it again or dismiss it as an action.

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.
