Ironwood

This spell allows the wu jen to change the tensile strength of wood to that of the finest steel. It only affects the hardness of the wood. Coloration, texture, and weight are unaffected. If cast on normal living plants, the spell has a 50% chance of working. If successful, it does not interfere with the normal growth of the plant but gives all parts of the plant, including leaves, flowers, and fruit the hardness of steel. If cast on a plant-like monster, a saving throw vs. spell must be made by the creature. If successful, the spell has no effect. Failure means the creature becomes rigid and paralyzed. The Armor Class of the creature becomes 0 and a hit roll must be made when striking it, since the hardness is imbued throughout the body of the creature.

The material component for this spell is a pinch of metal filings mixed with the sap of a willow tree.

Notes: Common in oriental settings; very rare elsewhere.
