Wall of Plasma (3.5e Invocation)

This ability functions like wall of fire, except radiates 1d6 fire damage per level out to 10 feet and 1d4 fire damage per level out to 20 feet. Passing through the wall is another story, provoking a Fortitude save DC 18 + Charisma. On a failed save, the target takes 2d6 fire damage per level, they are permenantly blinded, and are reduced to ash if they drop below 0 hp. A successful save halves the damage and negates the blindness, but still reduces them to ash if they fall below 0 hp.

The wall is opaque and glows bright white. All creatures with less than 8 HD are automatically blinded permenantly.

Only one instance of the wall may be active at a time, if another is invoked, the first vanishes.
