Tetsubo of Earth

You summon a tetsubo of pure earth, studded with all manner of stones. The weapon's default form is a tetsubo, but one Raise can change its form to any other heavy weapon of your choosing. The tetsubo has a DR of 2k2. When wielding this weapon, you may use your School Rank in place of your Heavy Weapon Skill if you wish. If you do have the Heavy Weapon Skill, the tetsubo grants you a Free Raise for the Knockdown maneuver (this bonus does not apply if you grant the Tetsubo to another person instead of wielding it yourself). The tetsubo disappears if it is lost from your hand. Instead of summoning for yourself, you may cause it to appear in the hands of an ally within 20 feet. He is treated as the caster for all purposes of the spell, but does not gain the Free Raise bonus.
