Venom Immunity

This spell affects one creature (which may be the caster). It renders the recipient immune to the effects of all toxins for the duration of the spell. A poison foiled by this spell is permanently neutralized; it does not take effect when the spell ends. Later attacks with the same poison, however, has normal effects. Unlike the more powerful neutralize poison, this spell has no effect on poisons already present in a creature. It will foil a poison that first takes effect in the same round that the creature receives a venom immunity spell.
