Note that this spell may also be harmful to the caster himself, as retaining high amounts of Rads is extremely dangerous. This spell can be used only through the caster's receptacle and not through the summon Radiance spell. This spell was crafted by Alasdair McAllister of the Brotherhood of the Radiance, and belongs to his collection of special low-level Radiance spells. With this spell, the caster agitates all matter in a ray starting at a given location within range and extending 15 more meters away from the caster. Every substance within the ray's area of effect will become very hot.
Different substances react differently to the ray.
Water heats to slightly below boiling level, air becomes warm but harmless, metals become red and cause 1d4 hp of damage per round of touch, leather and wood are not effected. If failed the target is infected by the Radiance rotting disease in a randomly chosen body part. This spell also has a devastating effect on metallic magical items. This spell requires use of the summon Radiance spell if away from the receptacle. This spell is mostly identical to discharge and requires a reserve of Rads.
