Ephemerate

You call upon the forces of the void to shield an ally. Choose a willing target, they are sent to a harmless demiplane for the duration of the spell. While there, the target cannot be targeted with any form of magic (such as a scrying spell), and if they are below 0 hit points they are stabilized at one hit point. If they were prone when this spell was cast, they may choose to be upright when it ends.
