Disc of Concordant Opposition

This spell is a weaker version of one used by the Boccob the Uncaring; when it is cast, the priest brings into being a disc that will blast most creatures into nothingness unless they have magic resistance. No attack roll is required when the priest hurls the disc at a selected creature.

A creature with fewer than 6 Hit Dice (or levels) and less than 35% magic resistance is destroyed if it fails a saving throw vs. spell. A creature with 6+ Hit Dice (or levels) suffers 40 points of damage, with a saving throw vs. spell allowed for half damage. A creature with 35% or greater magic resistance is unaffected.

The material components of the spell are a holy symbol of Boccob and a small iron and electrum wheel with a rod rising from the center of one side; this is flung at the target creature as the spell is cast.
