Agents of Faith: Crusaders of the Gods from Living Imagination Inc. provides a set of six feats for each domain described in the book. They are made available for characters of any class, but may be taken only with the feat slots gained every third character level. It is possible for a character to take five from a single domain, or from mixed domains, or of course none at all.
The sixth feat is the ‘Ascended’ feat and is granted to only a single character. Normally it might be the highest-level character following that god, or a lower-level character might be chosen. Looking them over, I think I would prefer to treat them either as fiat events or make them part of a capstone or something. They might be suitable as Epic tier abilities, but I have not decided to do that. I have included them in this document primarily for completeness.
The book describes how the DM may allow free choice of feats from your god’s domains, or might build a mandated path, such that if you do want the divine feats you must take the ones identified for your god.
I expect to be simpler here. Normally the feats are available every three levels (3, 6, 9, 12, 15); this is close enough to (1, 5, 9, 13, 17) that I’m not going to worry about it for now. I don’t doubt these will need adjustment later, but for now each domain talent shown below includes all non-Ascended domain feats identified in Agents of Faith: Crusaders of the Gods for that domain.
I am considering having the domain talents also give knowledge of the domain spells for those tiers (Expert levels 1 and 2, Heroic levels 3 and 4, etc.). This will obviously be helpful to spell casters, but it can also be useful to non-casters if it lets them use spell trigger and spell completion items related to their domains.
