Frost Rain

You freeze the air at several points within a 5-foot-radius sphere from a point within range of the spell, creating spheres that slam into targets at great speed. All creatures in that area must make a Dexterity saving throw. On a failure, a creature takes 3d6 cold damage, or half as much on a success.

At Higher Levels. When you cast this spell by spending Mana points equal to a 3rd-level spell or higher, the cold damage increases by 1d6 for each spell level above 2nd. When cast as a 5th-level spell or higher, this spell’s damage becomes glacial.
