Sunburst

This spell creates a brilliant flash of golden light. Undead within the area of effect takes 6d6 points of damage (no save). All other creatures within or facing the burst must save vs. spells or be blinded for 2-12 segments. Creatures without eyes, and those not sensitive to visible light, are not affected. A sunburst negates darkness spells within its area, provided the darkness was cast by someone of an equal or lower level than the cleric.
