Yes, but even so, the spirit called is one with the same alignment as you... And the spell says they'll attack regardless, so eh... How many DM's will actually randomly choose a different 6HD or less outsider from the same alignment as you just to spite your choice? This means they'll have to open up the MM or look it up in a splatbook somewhere, when they probably don't have anything in mind really, and it's just that much easier to just go to the page number and manual you point them to, rather than go and look elsewhere... Yeah, they'll probably grant you what you asked for.
OK, Fun Find:
The Ritual of Crucimigration, the one that turns you into a necropolitan, makes you lose a level, and then lose 1000xp.
Now here's the thing. The text says...
"If the loss of this much XP forces the necropolitan to lose another level, then it loses another level. No spell, not even restoration, can restore this lost XP. Petitioners may not spend experience points they don't have - if the level loss and the 1,000 XP cost drains a creature to 0 XP or less, it is destroyed, turned to dust, and can never be raised or revived again using any means. If the ritual is interrupted before it is completed, the petitioner is merely dead."
Read the underlined section.
ANY. MEANS.
Not Ressurrection. Not True Ressurrection. Not Wish. Not Reality Revision. Not even a deitie's SDA.
Nothing.
The guy is PERMADEAD, as in, you are now forbidden to EVER raise again from the living because i say so dead. And no one gets a say in it.
Even Deitie's SDA that are instakill stuff have a clause in them that says the creature can only be raised by another SDA that raises the dead from a higher DvR deity. Not this. This has nothing like that.
So, drain a Humanoid or Monstrous Humanoid to 2nd level, immobilize them, do the ritual to them, and they're now dead - FOREVER.
Isn't this or isn't this a fun find?
