Thanks for the ideas. I like a lot of these.
- Strength - small bonus to str / bonus to str skill checks that would be constant
Constant Str bonus? That could work. Just grant a scaling enchancement bonus to Str. Typically, I'd been doling out abilities at level 1, and every 5 levels as needed. I'm not sure if this progression would be suitable or not. Here's a tenative suggestion:
You get a +2 enhancment bonus to Str at level 5. Every five levels thereafter, this bonus increases by +2 (so +8 at level 20). Since it's enhancement, it would overlap with a lot of other sources. In the long run, this type of cleric wouldn't end up much stronger than anyone else who watned to, but I guess it would save him money on Str-increasing items and time on Str-increasing buffs.
- Sun - Cast light spells maximized or with inc CL / make more turning special abilities
Maximized light spells could work if done sparingly (1/encounter, or X/day based on cleric level). Extra turning effects? Maybe creatures damaged by the turning would have to save or be blinded and/or some other effects.
- Trickery - bonuses on granted class skills checks / bonus to att rolls when target denied dex bonus
Now there's something I didn't even consider. The attack bonus could work nicely. Sneak Attack could work too, although I don't want to overdo something like that. Nice!
- Protection - bonus to AC / reduce AC (the protection) of opponents (perhaps this with destruction too)
Are you thinking a static bonus to AC? Perhaps I could use a sieries of auraus like I suggested for War, but all protection-related. I'm not sure that I'd use it as a debuff (although maybe for Destruction, like you suggested).
Had some thoughts about the alignment type domains, you could do some increased CL bonuses at certain level increaments as well.
Increasing CL seems so generic, but I'm still at a loss on these. Maybe a bonus to save DCs against creatures of opposing alignments?
Also started on the spell list, what sources are you working from and willing to use?
Well, for now, all that's posted came straight out of core. I personally have the Spell Compendium, most of the Completes, and the PHB2. I think I could build a decent list from those.
