Agers Scepter

 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 creature within the line must make CON Save Throw. On a Fail, it takes 2d10+SM Cold damage, and is Frozen in place, becoming Restrained for 1 round. On a Success, it takes half damage and is Slowed for 1 Round instead.

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 other creature in a 5 ft radius circle. 

SM=Spellcasting Modifier. 

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