Except in this case, as I understand it, the gendershifting is literally a blessing from the god, not an innate ability.
Still don't like it and I don't really like the reincarnation fluff either. Corellion is a war god and I kinda like this a bit more.
The 2nd one when I 1st saw it all those years ago did not even recognise it as CL, DD Elf god smacking down an Orc god in the Eye. its Corellon.
Its a style thing I prefer a classical marble statue and Leonardo/Michaelangelo over say Picasso.
The last WotC fluff I used was the Fiendish Codex I and II from 3.5 and the flow on stuff from i in Savage Tide AP the Queen of Succubus whose name eludes me atm.
