Occultists can select occult feats as bonus feats. Members of other classes can take these feats as long as they meet the prerequisites.
These feats all possess strong ties to spirits, and the spirit realm in which they dwell, and are best suited for Occultists or characters who practice pact magic, though that shouldn’t stop players from taking these feats so long as they justify their choice to the GM’s satisfaction.
You can use a spirit’s power to drain vitality from foes.
Prerequisites: Bind spirit class feature, Furious Strike.
Benefit: At the end of a turn that you successfully deal damage with Furious Strike, you gain half of the additional damage dealt to your spirit’s favored enemy by the feat as temporary hit points for 1 hour.
Multiple uses of this feat do not stack.
