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 alter the duration of a spirit’s service.
Prerequisites: Bind spirit class feature.
Benefit: You can choose to extend or shorten the length of any pact you attempt to make with a spirit. During the ritual’s ceremony, select whether you wish to reduce or increase the pact’s length, as described below. Extending or reducing the duration of a pact prevents you from being able to expel the spirit with the Expel Spirits feat.
Extend: You can barter a spirit into increasing the duration of a pact beyond the usual 24-hour period. You can increase the pact’s length by 24-hour increments, to a maximum of 120 hours (5 days). For every 24-hour increment you increase the pact’s length, you gain a +2 bonus on your binding check to forge a good pact with the spirit (maximum +10).
Reduce: You can barter a spirit into reducing the duration of a pact below the usual 24-hour period. You can decrease the pact’s duration by 4-hour increments, to a minimum of four hours. For every 4-hour increment you reduce the pact’s length, you take a -2 penalty on your binding check to forge a good pact with the spirit (maximum –10).
Normal: Once you forge a pact with a spirit, that pact lasts for 24 hours.
