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 are aligned with a constellation and its spirits.
Prerequisites: Bind spirit class feature.
Benefit: Select one constellation. Add +2 on binding checks made to forge pacts with spirits who belong to that constellation and +1 to the saving throw DCs of those spirit’s granted abilities. You lose this feat’s benefits while you are bound to a spirit who belongs to the selected constellation’s opposed constellation.
Special: You can select this feat multiple times. Its effects do not stack. Instead, each time you select this feat, select a different constellation for its benefits to apply. You cannot select a constellation with this feat that opposes a constellation that you already possess with Constellation Focus.
