Errors and Mistakes

The magus gains elemental penetration for non elemental

Elemental Penetration [General]
Choose an element, such as dark, earth, fire, ice, light, lightning, water, or wind. Your spells of that element are especially potent, breaking through element resistance more readily than normal.
Benefit: Spells of the element you select are harder to resist. Any elemental resistance on a creature is considered 2 less when determining damage from a spell of the element you select.
Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new element.

Not sure if its a mistake, but if not, then I have so many questions. Is there such a thing as non elemental resist, how do you get it, and what creatures get it?

The crystal dragons and mimics are immune to non-elemental damage. The iron giant family has 10 non-elemental resistance. These are creatures I've made so I don't really know of any outside of that.
