This spell forms a mystical, swirling mass of magma around a common shield. The priest must be able to use a shield to cast this spell, and the shield is destroyed when the spell ends.
Anyone in melee with the priest takes 1d4 points of heat damage if a successful saving throw vs. spell is not made each round. Any attack that misses the caster by exactly 1 point on the attack roll has hit the shield; a weapon that hits the shield must make a successful item saving throw vs. acid or be destroyed.
The caster is protected from the intense heat the shield generates, but not from any other heat source.
Notes: Uncommon for priests from the Dark Sun setting.
