Granade

The spellcaster takes an object, commonly a simple
rock, imbues it with magic energy and throws it at
their target, whereupon it explodes into hundreds of
fragments. The spellcaster picks a target point within
14''. Every figure, including allies, within 1.5'' of that
point immediately suffers a +3 magic shooting attack.
Use the target point as the origin of the attack for
working out line of sight and cover.
