DESCRIPTION

You create a cloud of corroding energy that destroys metal. This functions as a solid fog spell, but in addition any non-magical objects made of iron or iron alloys within the area are destroyed, including weapons and armor. A non-magical item that is made of non-iron metal, such as mithral or adamantine, instead take 1d6 damage each round; this damage bypasses hardness.

A creature that is made of iron takes 5d6 points of damage + 1 per caster level (max +10) each round it remains in the cloud. A metallic creature that is not made of iron takes half this damage.

The cloud is heavy and thick enough that it has difficulty penetrating containers; any metal items secured in a closed container, such as a scroll box or a coin purse, are generally unaffected (unless the container is destroyed first by the cloud of corrosion).
