So, suppose I'm a tiefling, and I take the Crossblooded Archetype with Rakshasa + Infernal.
Fiendish Sorcery (a tiefling racial ability) grants an effective +2 CHA for sorcerer spellcasting purposes if you have either the Infernal or Abyssal bloodlines.
Improved Fiendish Sorcery (a feat) grants an effective +2 CHA for sorcerer spellcasting purposes if you have either the Rakshasa or Shadow bloodline.
Would I get a total of +4 effective CHA, then? Seems reasonable to me (and not overpowered; may be just enough to actually justify the downsides of Crossblooded).
I can't find that feat to check its text, but I see no reason why that shouldn't work.
It's in Blood of Fiends; I don't think I'm supposed to just copy paste, but the improved fiendish sorcery text mirrors the fiendish sorcery text, just with two different bloodlines listed: "...treat your charisma score as 2 points higher for all sorcerer class abilities."
In that case it would work fine.
But that reminds me I should get that book :)
Cool; thank you.
I dont think it stacks, it hink the feat allows you to apply the archetype to Bloodlines it would normally not apply to. I really dont think stacking a +4 charisma modifer to every class ability was intended.
It only works if the sorcerer has two different bloodlines (as granted by the cross-blooded archetype). So I think it's fine; cross-blooded has a fairly steep penalty as it is.
It should be fine, but I seem unable to check as well. Also note that it is an untyped bonus, so should stack.
Ps just found the first one, and on the srd, it just says all sorcerer abilities.
