You are naturally resistant to fey magics.
Prerequisites
Benefit
You are treated as a fey for any magic that beneficially affects fey creatures and become immune to any spells or abilities that do not affect fey. For example, several common fey glamors and illusions do not affect other fey, allowing you to instantly see through them.
In addition, your bonus to saving throws against enchantment spells or effects from your Fey Bloodline feat increases by 1 for every two Fey Feats you possess.
