Protection from Rust

Using this spell, the mage can protect an item from mundane rust (oxidation) for one year per caster level. The spell also provides a one-time bonus of +1 per three caster levels on saving throws versus rust monster effects. The spell is intended for use on small to medium metal items (daggers, swords, pieces of armor), not large metal structures.

The material component (consumed) is a specially formulated lacquer, which the mage applies to the item to be protected. This lacquer costs not less than 5 gp per application.

A shipmage who regularly uses this spell on the ship's equipment reduces the yearly maintenance cost of the ship by 10%.
