Anticold Sphere (EFA - A)

You conjure a spherical energy field, centered on yourself and which moves with you, which protects against cold. All creatures within the sphere gain immunity to cold damage as well as levels of exhaustion due to cold conditions.

In addition, any creature of ice or cold must make a Charisma saving throw to enter the sphere, and while in the sphere makes attack and saving throw rolls with disadvantage.

The reverse of this spell, antifiresphere, protects against heat and fire-based creatures and effects in the same way.
