Hello again,
as far as I know, the elemental-blooded native outsiders that are declared as playable races (oread, ifrit, undine and sylph) gain some bonus if they happen to choose the associated elemental bloodline as a sorcerer, or if they pick a cleric domain associated with their element.
So far, so good.
Now, let's assume an undine character becoming an Oracle... and following the mystery of 'Waves'... would she qualify for a bonus akin to he sorcerer's, in your opinion?
RAW indicate nothing of the sort...
RAW no
but you'd be welcome to houserule a +2 effective cha for oracle powers which for the most part is either extra use and or +1DC save
although not sure on the printing order, if undine printed after APG then paizo decided not to incldue oracles in those elementals, if printed before then that prob the only reason its not there.
