Magical Ball

From the Rulebook Glossary:
A type of magic that involves charging a ball that is then thrown at a target. Magical balls are reusable. The number of times a magical ball is bought determines the maximum number of balls that may be charged or in effect at once. All magical balls charged at the same time must be thrown at the same time. You must repeat the incantation once for each ball to be charged; i.e. to charge four Fireballs you would have to repeat “Fireball” twenty times. Magical balls, once cast, remain charged for two minutes, after which they must be recast. Magical balls cast with the left hand may be transferred to the right hand for throwing. When thrown, all hits by a magical ball count except head or throat shots. This includes foot shots, tail hits and grazes. A hit to a hand holding a weapon affects it as if the ball it hit the weapon – which in some cases affects the holder (e.g., Iceball). A magic-user may carry a maximum of 12 magical balls, regardless of how many were purchased. Streamers on magic balls may be no longer than 12 inches.
