Natural Immunities
Natural immunities describe attack forms that either have a lesser effect upon creatures, or which have no effect whatsoever. This first variety is called a "resistance," and may mean that the attack form is minimized or that the creature receives an unusual saving throw bonus against that kind of attack. Creatures with a great many immunities can be hard to destroy with magic or with weapons; most creatures like this are unearthly, from other planes of existence.
Some forms of immunity and resistance are provided by spells or magical items.
