Sunburst causes a globe of searing radiance to explode silently from a point you select. All creatures in the globe are blinded and take 6d6 points of
damage. A creature to which sunlight is harmful or unnatural takes double
damage. A successful Reflex save negates the blindness and reduces the
damage by half.
An undead creature caught within the globe takes 1d6 points of
damage per
caster level (maximum 25d6), or half
damage if a Reflex save is successful. In addition, the burst results in the
destruction of any undead creature specifically harmed by bright
light if it fail its save.
The ultraviolet
light generated by the spell deals
damage to fungi, mold, oozes, and slimes just as if they were undead creatures.
