As an action, you create a shimmering wall of bright light at a point you choose within 35 meters. The wall appears in any orientation you choose: horizontally, vertically, or diagonally. It can be free floating, or it can rest on a solid surface. The wall blocks line of sight, but creatures and objects can pass through it. It emits bright light out to 35 meters and dim light for an additional 35 meters.
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 Fortitude saving throw. Undead and oozes have disadvantage on this saving throw.
On a failed save, a creature takes 2d6 radiant damage and is blinded until the end of its next turn.
On a successful save, it takes half as much damage and isn’t blinded.
You can increase the damage by 1d6 for each additional mana or psi expended.
