Nystul's Lightburst

This spell summons a burst of energy from the Positive Material Plane. While creatures without eyes cannot be blinded, all other creatures within or facing the sudden blaze of energy are blinded for one round, with no saving throw.

In addition, undead, creatures from the Negative Material Plane, and beings from the lower Outer Planes that are caught within the area of effect suffer 1d6 points of damage per level of the caster to a maximum of 10d6 (save vs. spell for half damage, undead have a penalty of-2).

The material component is a small, solid gold orb worth 500 gp. It is destroyed after the spell dissipates.
