Do You Want to Play in the Snow?

Until the spell ends, you create a storm of snow and hail in a 500-foot radius around you. The area is heavily obscured, and open flames in the area are extinguished. The area has freezing temperatures; if creatures are in combat, at the start of each of their turns creatures in the area must make a DC 10 Constitution saving throw, and this DC increases by 5 for each failure a creature has already accumulated. If they aren’t in combat, creatures in the area must make this saving throw every hour. On a failure, the creature takes 3d6 glacial damage and gains 1 level of Exhaustion; a creature can’t exceed 4 levels of exhaustion this way. On a success, the creature takes half the damage.

Creatures with vulnerability to cold or glacial damage have disadvantage on this saving throw.

The ground in the area is covered in slick ice, making it difficult terrain. When a creature enters the spell’s area for the first time on a turn or starts its turn there, it must make a Dexterity saving throw. On a failure, the creature falls Prone.

If a creature is concentrating within the spell’s area, it must make a Constitution saving throw against your spell save DC or lose concentration.

Allies in the area can see normally through the spell and have advantage on their saving throws.

If you cast this spell in the same area every day for the next 7 days, its effects become permanent in the area.
