Turn Lightning

This spell provides the caster with a special form of protection against electricity-based attacks by turning them back upon their source, without harming the caster of turn lightning. For example, if a lightning bolt is thrown at the caster, turn lightning causes the bolt to return to its caster, who suffers damage from his own spell (though any saving throws still apply). Even if the lightning bolt is cast at a range which normally prevents a rebound from reaching its caster, turn lightning empowers the lightning bolt so that it completes the return trip. (Note that a spell like cull lightning causes lightning that originates from a cloud and not the spellcaster, so turn lightning merely sends the lightning back to the heavens.)

Electrical attacks that cannot be reflected back on their source for logical reasons (e.g., a sustained “field” of electrical energy) are not affected by turn lightning, but the caster is immune to such assaults while the turn lightning lasts. In any case, the spell lasts until its duration expires or it is removed with a limited wish; dispel magic has no effect.

The material components for this spell are a small ball of gum and a silvered glass mirror, both of which are consumed upon casting the spell
