Swordward

This spell creates a guardian effect in a clearly defined area of shimmering silver-gray air. Within its confines, all points of damage done to foes by the attacks of lawful good-aligned beings are gained as extra (or replace lost) hit points by the attacking lawful good beings. Moreover, all edged weapons wielded against lawful good individuals strike at a -3 penalty on attack rolls and a -3 penalty to every die rolled for damage rolls (for example, 2d6+3 becomes 2d6+3-6). The caster can choose to make the swordward fill any area between 5 and 60 square feet, but its potency is unaffected by the size of its coverage.

A swordward cannot coexist with a blade barrier. If either spell is cast so as to come into contact with any part of the area of effect of the other, both spell effects vanish instantly in a thunderous explosion, and all beings in the former areas of effect of both spells take 6dl2 points of blast damage; this damage is halved if they make a successful saving throw vs. spell. All items in the same area in such an event must make successful item saving throws vs. magical fire or be destroyed. Any beings located in the overlap area where the two spells met are allowed no saving throw, and items in that area must make successful saving throws vs. disintegration, not magical fire.

The material components of a swordward are an edged weapon or a fragment of a blade from an edged weapon that has drawn blood in battle, a piece of lodestone, and an amethyst of at least 5 gp value.
