By means of this spell, the priest creates a magical lens high in the air, with which he can direct intensified rays of the sun against his enemies. The caster must be in the sunlight for the duration of the spell. Once cast, the priest can attack with the lens twice per round, against one or two creatures within range of the spell. Attack rolls are made for each attack, and the priest suffers no nonproficiency penalty. Targets under cover receive benefits for both cover and concealment. Each hit inflicts 2d6 points of damage. Creatures resistant to heat or fire take only half damage.
The spell can be used to ignite flammable materials. When doing so against non-mobile targets, no attack roll is necessary - any normally combustible materials (cloth, wood, paper, and so on) ignite. Personal equipment can be targeted, but the priest must, make a successful attack roll with a -4 penalty. If hit, the article of equipment ignites; burning clothing inflicts 1d6 points of damage for 1d6 rounds or until discarded. Burning shields become useless. The flames so created are not magical and can be extinguished normally. Magical darkness can negate the effects of this spell, magical shade reduces damage by half.
The material component for this spell is a small, round piece of glass.
Notes: Common for priests from the Dark Sun setting; otherwise, very rare.
