The character receives a +2 racial bonus on saving throws against mind-affecting spells.
Note: Despite the feat name, the bonus is applied even if the spell belongs to a different school of magic. For example, this ability will also increase the Will saving throw against a spell like Deep Slumber (Enchantment school). The bonus generally applies against all spells that require a save against mind-affecting spells. Thus, this feat functions exactly like Hardiness vs. Enchantments.
