Cone of Cold

Source cone of cold

The damage dealt increases to 1d10 points of cold damage per caster level (maximum 15d10). Any creature that fails its save is partially encased in ice, reducing its speed by half. Creatures with the cold or incorporeal subtype or immunity to being grappled are immune to this effect. The reduced movement lasts until the ice is destroyed. Destroying the ice requires a successful Strength or dispel check against the spell's DC, or dealing bludgeoning or fire damage equal to 1 point per caster level to the creature.

Augmented: You can expend two uses of mythic power to transform the spell's cold into a barrage of giant hailstones, icicles, or shards. Half the spell's damage is your choice of bludgeoning, piercing, or slashing damage, and the other half is cold damage.
