This spell enables the character to change all metal objects within its area to wood. Weapons, armor, and other metal objects carried by creatures are affected as well. Magic objects made of metal effectively have SR 20 + caster level against this spell. Artifacts cannot be transmuted. Weapons converted from metal to wood suffer a –2 penalty to attack and damage rolls. Armor converted from metal to wood loses 2 points of AC bonus. Weapons changed by this spell splinter and break on any natural attack roll of 1 or 2, and armor changed by this spell loses an additional point of AC bonus every time it is struck by a natural attack roll of 19 or 20.

Only a limited wish, miracle, or wish or similar magic can restore a transmuted object to its metallic state. Otherwise, for example, a metal door changed to wood is forevermore a wooden door.
