Ball of iron is a special form of the spell wall of iron, useful for offensive combat. Any spellcaster who has wall of iron can cast ball of iron and vice versa. The spell does 1d10 points of damage for every two levels of the spellcaster, rounded down, to anything hit by it (i.e.: 5d10 at tenth, 6d10 at thirteenth, etc.). Further, if the saving throw is failed, there is a percentage chance equal to 10 plus the Armour Class of the target that a limb (i.e.: an  arm or leg, not the head) is crushed under the ball and rendered useless. Huge and gargantuan creatures (12 feet or higher) are immune to limb crushing. For purposes of breaking down portals, the ball strikes with a force equal to 25 Strength. Moving the ball (not lifting it) also requires 25 Strength. The ball does siege damage (see the AD&D Battlesystem) equal to a heavy catapult or a boulder thrown by a storm giant, whichever is greater.
