Create Plane

You create a plane from your mind and whatever you're thinking about during the hour of preparation is inserted into this realm. This includes the general physics of this plane. You must make a DC 22 Wisdom Intelligence check to keep your plane clear of things you think of accidentally. It can consist of anything that the player or DM decides depending on what they roll in the INT check. Once the ritual is finished, the player and any willing creature they decide is transported to their new plane. Upon arrival, the player can never cast this spell again and must replace the spell with another 9th level spell and they have 3 levels of exhaustion. Although, the player can transport between their plane and their original plane whenever they like, but it takes an hour.
