I was bored.

This spell creates an intense burst of light centered on the caster, destroying magical effects causing darkness and blinding foes.
All supernatural and spell-like effects causing darkness are instantly dispelled. This includes
Darkness,
Deeper Darkness, and any other spell that causes a darkness effect. Abilities that cause darkness are negated, though may be activated again in subsequent rounds.
In addition, all creatures within the area of effect must make a Reflex save or be blinded. A blinded creature, in addition to the obvious, suffers a 50% miss chance in combat (all opponents have full concealment), loses any Dexterity bonus to AC, grants a +2 bonus to attackers' attack rolls (they are effectively invisible), moves at half speed, and suffers a -4 penalty on most Strength- and Dexterity-based skills. A failed Reflex save dazes any creature below 5 HD.
A creature with alternate senses (blindsight, termorsense, et cetera) suffers no penalty from blindness. A creature with its eyes closed before the casting of the spell automatically succeeds at the Dexterity save for blindness, but still may be dazed.
The material component for this spell is a small bit of phosphorus, which bursts into flames on completion of the spell.
