Metal to Rust (Reversible)

This spell allows the wu jen to reduce ferrous metal to a crumbled pile of rust with a single touch. Upon casting the spell, the wu jen touches the item (rolling a hit if necessary), causing it to fall away in large flakes of rust. Normal metallic items do not receive a saving throw-the effect is automatic. Magical metals make a saving throw vs. disintegration (17 for hard metal, 19 for soft metal and jewelry), receiving the appropriate bonus to the saving throw for the strength of the magic. Magical items of ferrous content that do not have a specific plus value (an iron amulet of ESP for example) should be assigned a bonus by the DM based on their magic (usually +0 to +5). Ferrous creatures must be touched with an attack roll. If no other result is specified, the creature takes 1d6 points of damage per caster level with no saving throw.

The material component for this spell is a flask of seawater.

The reverse of this spell, rust to metal, restores a rusted item to its original condition if at least 90% of the original material is present.

Notes: Common in oriental settings; otherwise very rare.
