Entity: Superstition

Source Player Core 2 pg. 75 ^1.1

A deep distrust of magic drives you to forgo and counter the metaphysical nonsense of spellcasters. Whether you’re a member of a superstitious family or culture that distrusts magic, a warrior in constant battle against wizards and witches, a survivor of a magical accident that instilled an intense aversion in your mind and body, or a scion of a bloodline known for its magic resistance, your rage is inimical to magic. This makes you an excellent mage hunter but slow to trust practitioners of magical arts.

While raging, you gain a +2 status bonus to all saves against magic. Increase your damage from Rage from 2 to 3, or 4 against creatures you have witnessed Casting a Spell within the last hour. When you Rage, you regain Hit Point equal to the temporary HP you gained from the Rage action; you then can’t regain HP in this way again for 10 minutes. While raging, if you willingly accept the effects of a magic spell or effect, you are frightened 1. You cannot reduce your frightened condition below 1 as long as you are affected by the spell or effect.
