concentration, 5 minutes/mana or psi

As two actions, you create a vertical wall of whirling, razor-sharp blades made of magical energy. The wall appears within 20 meters and lasts for the duration. The wall provides three-quarters cover to creatures behind it, and its space is difficult terrain.

When a creature enters the wall’s area for the first time on a turn or starts its turn there, the creature must make a Reflex saving throw. A creature takes 2d10 slashing damage on a failed save, or half as much damage on a successful one.

Augment

You can increase the damage by 1d10 for each additional mana or psi expended.
