At 6th level, you gain the ability to adopt a humanoid’s persona. When a humanoid dies within 30 feet of you, you can magically capture its shadow using your reaction. You retain this shadow until you use it or you finish a long rest.
Does this mean you lose the shadow at the end of a long rest even if you haven't yet used it?
