As an action, a blast of cold air erupts from your hands. Each creature in a cone must make a Fortitude saving throw.
On a failed save, a creature takes 3d6 cold damage and is slowed 1 until the end of its next turn.
On a successful save, a creature takes half as much damage and isn’t slowed.
A creature killed by this spell becomes a frozen statue until it thaws.
If the blast of cold air strikes a body of water or a liquid that is principally water (not including water-based creatures), it freezes the liquid to a depth of 15 centimeters over the area. The ice is an instantaneous effect, but persists as nonmagical ice. Under temperate conditions, the ice lasts 1 minute. Creatures that were swimming on the surface of frozen water are trapped in the ice. A trapped creature can use an action to make an Acrobatics or Brawn check (its choice) against your spell save Difficulty to break free.
You can increase the damage by 1d6 for each additional mana expended. If you expend 4 or more mana, the slowed level increases to 2.
