Transform the Elements

You convert can convert one of the elements from fire, water, earth, air into another element. The space this occupies has a max size of 10 feet cube but you can choose any size cuboid up to this max amount.

If a creature occupies this space and can still occupy after the transformation, they stay where they are. If they cannot occupy the space after the transformation they get pushed to the closest available space and must make a Dex saving throw against your spell DC. If no available space, the element forms around them and they have to push there way up.

Note. If you choose to turn air into earth, the earth is not a rigid body and will fall into a pile upon being created.

Example. You can turn the earth under a player into air causing them to fall down into a pit.
