Robe of Stars

This black robe is embroidered with small silver stars. You gain a +1 bonus to saving throws while you wear it.
Six stars, located on the robe's upper front portion, are particularly large. While wearing this robe, you can use an action to remove 1 of the stars and use it to cast Magic Missile as a 5th-level spell.
As an action you can shift between the Material and Astral Planes.
