  Fire Ball is the most destructive spell in pyromancy. It throws a large ball of fire that flies straight ahead until it hits something.<~><~>  When it lands it goes off with the force of one block of TNT. It breaks the blocks around it and sets the ground burning.<~><~>  It deals 16 damage to whatever it strikes, and the same again to anything caught in the blast.<~><~>  The blast does not spare the caster. Throw it far, and never at your own feet.
