Cone of Frost

A frigid wave of blue-white light spreads from the caster's hand. Each creature in a 15-foot cone must make a Constitution saving throw. A creature takes 1d8 cold damage on a failed save, or half as much damage on a successful one.

A creature killed by this spell becomes a frozen statue until it thaws.

 it takes 1d8 cold damage, and its speed is reduced by 10 feet until the start of your next turn.

The spell's damage increases by 1d8 when you reach 3rd level(2d8) 5th level (3d8), 11th level (4d8), and 17th level (5d8).
