Need suggestions for a (very special) NPC

[Ceska]

I want to make a Wizard 3/Psion 3/ Cerebmancer 10 NPC for my campaign.
It is a kind of memory of an oracle the PC´s encountered a while ago and it made herself a home in one of the PC´s (it was able to take the PC as a "host", because the PC was holding a campaign-specific item). The "Oracle" is able to overtake the host in very special situations, so taking the physical attributes of the host and using its own mental stats. The Host is a Rogue 2/Wizard 3/Mindbender 3.

Now I need to write the whole thing down and there´s were I need your help. Which Feats should I take? As discipline for the psion I thought about the (obvious?) Telepath. What kind of spells and powers would you suggest? Shall I take the Wizard as an Specialist?

Feel free to use any D&D 3.5 Book (WotC), since I have access to most of them.

A, I nearly forgot the mental stats: Int 20/Wis 13/Cha 16

Thanks for any reply in advance!

Anyone?

If you have another idea for such an "Oracle" (than the class combination I gave above), feel free to tell me your idea!

*bump*

I realized memorizing spells per day will be a problem, since the original spellbook of the "Oracle" is gone and the spellbook of the host is not nearly as filled as the lost one. The "Oracle" will be able to memorize some spells, but thats it. Thats why I selected Spell Mastery for a feat, thinking about taking it once again. Thoughts?

88 looks and no reply? Is the idea that bad? *sigh*
Okay, i give up. Thanks for looking.

The Spell Mastery feat would help a bit with the spellbook problem.

If your willing to mess with the rules a bit, combine the Alternative Spellbook (tattoos) pg186-187 from Complete Arcane with being possed. Specifically what I mean is whenever the host is taken over, the tattoos magical appear on the body at their respective locations. This will allow you to keep more spells for the NPC without having to write them in the PCs book.

Nice idea (and thanks for posting!), but since the PC´s have met (the ghostly image of) the "Oracle" I would have a hard time explaining why this tatoos appear, because the image had no tatoos anywhere. I think I have to stick to the Spell Mastery Feat until the Oracle is able to get a own book (and, in the end) leave the host. The other feats I selected are: Maximise Spell, Sculpt Spell, Craft Psicrystal, Improved Ini and Craft Wondrous Items.
Any other ideas about that?
