Very cool class. You really do great work. Scaling with Level, worshippers, focus on diefic powers rather than ultimate power, etc., very cool
Thoughts below.
* Often you say "at 20 HD you can do this very cool thing". A tweaked bard with inspire greatness can give +6 to +12 bonus HD. I'd specifically exclude that effect - perhaps just put this in a footnote or some such. On the other hand, it might be fun to allow +1 effective HD per divine characteristic so dedicated while in your Godly Relm", or some such.
Divine Rank:The god has a Divine Rank equal to her god level, which determine the power of several of her godly abilities. Divine Rank cannot be boosted by any other means.
Reading this makes me think that you can only boost Divine Rank by boosting God Level. However, Bloodlines would boost your God Level, so perhaps that should be specifically made ineffective.
Portfolio: At first level the god chooses a portfolio over which she will focus, like Love or Farming or Murder. She gains an insight bonus equal to 2+1/2 HD on all Craft, Knowledge, Profession, and Perform checks directly related to her portfolio.
Skills are cheap ... I'd even want this to be a higher bonus. A God of love having +12 at 20th level to seduction or matchmaking just isn't that great. I realize there are Divine Powers for this too, but there is no great harm in allowing skill totals to go over the top.
God Field- The Demigod gains a Divine bonus to AC equal to her Divine Rank. If she has 20 or more HD, she also gains a Deflection bonus to AC equal to her Cha mod (minimum +1).
This seems a little bit high, given that she also gets Divine Rank to AC as a Natural Armor Bonus. This makes this the highest AC in any class (your stuff or official stuff).
God Domain- Choose a cleric Domain ... you can use the domain power a number of times per day equal to your Divine Rank
luck: you 1 re-roll per level
Celestial: smite evil 1/lvl
Meditation - free empower 1/lvl
It seems a little strong.
Also, I think that in instances where it is 1 round / cleric level, that the god should be able to use it more than that.
God Skill-Three times per day per HD you can add your Divine Rank on any one skill check, ability check, caster level check or turning check you perform (but no more than once per roll). This takes no action but you need to choose to use this ability before actually rolling the dice. If you have 20 or more HD, then you can choose to use this ability after seeing the result of this roll.
It's a little powerful.
Note that this includes, initiative checks and maneuver checks (trip / bull rush / grapple ..), as part of that list.
Also, 3*HD is an awful lot ... might as well make it at will at Divine Rank = 11.
Perhaps this could be broken into 2 or 3 different abilities?
God Toughness-All your current and future HD are automaticaly maximized.
Perhaps this should only apply to HD gained while in the god class?
While in the god class this is ~ +2.5HP/lvl. However, as a 1 level dip ... it may be too good (it's already a very! dipable class).
Godly Realm:
- I'd like that for some combination of Divine Characteristics and Salient Divine Abilities you can increase you effective Divine Rank and or HD for the purpose of abilities.
- Perhaps Divine Characteristics can be spent to increase Divine Rank while in Godly Realm
- Perhaps There can be a salient Divine Ability which will increase your effective HD (possibly fatiguing?)
At some point I'll get around to looking at the salient Divine Abilities.
Also - random thought: there should be some way to get more skill points, armor and weapon proficiency, etc. Perhaps you can spend a Divine Characteristic? It is amusing that the god of war isn't proficient with most weapons.
As always, very cool work.
Best,
David
