As an action, you can create a vial of liquid that tastes of snow. A creature can take the contents into their mouth and spit it out as an action as a blast of cold air erupts forth. Each creature in a cone or line must make a Reflex saving throw.
On a failure, it takes 3d6 cold damage and is slowed 1 until the end of its next turn.
On a critical failure, it takes twice as much damage and is slowed 2 until the end of its next turn.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
A creature killed by this spell becomes a frozen statue until it thaws.
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.
