Earthbound Weapon Property
Aura Moderate conjuration CL 9th
Price + 1 bonus.
An earthbound weapon has a Small earth elemental bound to it, and has a heavy, crystalline appearance. As long as the wielder and his opponent are both touching the ground, the weapon grants its wielder an additional +2 bonus on attack and damage rolls. If the wielder is flying, the weapon’s enhancement bonus from this property does not apply to his attacks (though the +1 enhancement bonus on his attack rolls for using a masterwork weapon still applies).
Requirements Bind Elemental, lesser planar binding.
Cost + 1 bonus.
