As two actions, you create a wall of ice on a solid surface within 20 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, a creature takes 6d8 cold damage, or half as much damage on a successful save.
The wall is an object made of ice that blocks line of sight. The wall can be damaged and thus breached. It has 12 Defense, 2 Soak, and 15 Health per centimeter of thickness, and it is vulnerable to fire damage. Reducing a panel to 0 health destroys it and might cause connected panels to collapse at the GM’s discretion. When destroyed, it 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 6d8 cold damage on a failed save, or half as much damage on a successful one.
You can use this spell to bridge a chasm or create a ramp. If you create a span greater than 4 meters in length, you must halve the size of each panel to create supports. You can crudely shape the wall to create crenellations, battlements, and so on.
If you maintain your concentration on this spell for its whole duration, the wall becomes permanent and can’t be dispelled. Otherwise, the wall disappears when the spell ends.
You can increase the damage by 2d8 for each additional mana or psi expended.
