As an action, you create a wall of ice on a solid surface within 35 meters. If the wall cuts through a creature’s space when it appears, the creature within its area is pushed to one side of the wall and must make a Reflex saving throw.
On a failed save, the creature takes 4d8 cold damage, or half as much damage on a successful save.
The wall is an object that can be damaged and thus breached. It has 12 Defense and 30 Health per 3-meters section, and it is vulnerable to fire damage. Reducing a 3-meters section of wall to 0 health destroys it and leaves behind a sheet of frigid air in the space the wall occupied. A creature moving through the sheet of frigid air for the first time on a turn must make a Fortitude saving throw. That creature takes 3d8 cold damage on a failed save, or half as much damage on a successful one.
You can increase the damage by 2d8 for each additional mana or psi expended.
