Effulgent Palisade

When you cast this spell a wall of golden light arcs into the sky, rightly cutting the horizon in half. The wall extends 500 feet long in any orientation you choose, is 100 feet high, and blocks line of sight. The wall can be formed into a dome with a radius of 50 feet. The wall radiates bright light within 100 feet of it, and dim light for an additional 50 beyond that; this light counts as sunlight. Creatures attempting to pass through this wall must succeed on a Constitution saving throw or suffer 10d10 radiant damage and 10d10 fire damage, or half as much on a successful save. Creatures failing the save are blinded.

When you cast this spell, a wave of light pulses out from the wall on a side you choose, either filling the dome, or washing out for 100 feet from the wall, if you chose the wall conformation. Any patches of magical darkness caught in the wave of light are instantly dispelled. Creatures caught in the area must make a Constitution saving throw or suffer 10d10 fire or radiant (your choice) damage, or half as much on a save. Creatures that fail the save are blinded. As an action on your turn you can cause the wall to emit this wave of light again while the spell persists.

Creatures blinded by this spell are blinded until a restoring effect equal to or greater than a greater restoration affects them, targeting the effect.
