Yrolomere’s Icy Void

You plunge a creature into a cold void of nothingness. The target must succeed on a Charisma Saving Throw or be transported into a cold area of the Astral Plane. While inside the Astral Plane, the target takes 9d10 Cold Damage at the start of each of its turns. The target does not need to breathe for the duration of this spell, and it it transported to the closest unoccupied space to where it was when it failed its saving throw.
