 You draw from the Elemental Power of Frost. A frigid flowing beam of blue-white light streaks forward from your outstretched hand in a 60ft line. Any enemy creatures within the line must make a CON Save Throw. On a Fail, taking (2d10)+SM in Cold damage, and become Frozen in place, becoming Restrained for 1 round. On a Success, it takes half damage and is Slowed for 1 Round instead.

Frozen: A Frozen creature is encased in ice and have the Restrained and Incapacitated Conditions and are Vulnerable to Fire and Bludgeoning damage.

Slowed: Movement Speed reduced by 10ft.

If any creature dies from damage caused by this spell, that creature explodes with Cold energy doing (2d10) Cold damage to any enemy creatures in a 5 ft radius circle, who make the same DEX Save.

SM=Spellcasting Modifier. 

At higher levels: The spell's damage increases by (1d10) for each spell level 3rd or above.
