I like what you suggest for the DR listing.
I could go for crown of glory, greater shout, spike stones. Does that work for you?
Any other SAs, or are we ready to deal with spells?
Let's go level by level I guess, so we can balance the arcane and divine ones as we go. Starting at 0th level:
Sorc (9 known, 6/day): acid splash, arcane mark, detect magic, mage hand, mending, prestidigitation, ray of frost, read magic, resistance
Cleric (6/day): cure minor wounds [×2], detect poison, guidance, resistance, virtue
I just picked Pearl's cleric spells, since they seemed reasonable, but I varied the arcane ones a bit. How's that?
I already put mending, but I'd be ok with substituting open/close and touch of fatigue for acid splash and ray of frost.
If you want to swap in something else for resistance in one list or the other, sure. But it's hard finding useful spells at this level!
I think I prefer your original idea of swapping resistance out of the sorcerer spells, so let's take the first option.
"Opal has access to all the domains available to the neutral dragons he rules. (For the jade, moonstone, Mystaran jade, Mystaran onyx, and pearl dragons, these are Plant, Knowledge, Charm, Water, and Luck.)"
3) I didn't see a domain for jacinth, which I think might be a mistake in that conversion. Or else the * on the CL level is itself a mistake, and they're not supposed to have divine casting. I don't remember.
4) I chose Plant over Trickery for jade, Knowledge over Healing for moonstone, Charm for Mystaran jade (already had the other 2), Water over Animal and Darkness for Mystaran onyx, and Luck over Weather for pearl. But I could see switching some. I like going with Plant and Knowledge, though, since they both show up for 2 of the dragons.
3) I didn't see a domain for jacinth, which I think might be a mistake in that conversion. Or else the * on the CL level is itself a mistake, and they're not supposed to have divine casting. I don't remember.
2) Amber has druid, not cleric casting, so we should decide if we want to allow druid spells.
