In "Volo's Guide to the Outsiders of the Forgotten Realms," I really liked the two celestials that were presented, The Harmonious Choir of the Words, and The Sliver.
Can anyone point me to an online source that might have their level adjustments? A Savage Species progression would be ideal, but I'm sure that's too much to hope for.
Help, please!

I didn't see this in the errata, but did anyone notice that the Sha'ir's spells/day and spells/known tables don't match up?
For example, a 17th-level sha'ir has one 9th-level spell slot, but he doesn't know any 9th-level spells.
Is this a mistake? Is the slot supposed to not be there? Or is the slot used for a metamagicked spell, or a normal lower-level spell or something?
Just curious.
