In preparation for a Planescape game slanted toward strange and exotic characters, I have my eye on the Tsochari from the Lords of Madness book. For those unfamiliar with them, they're tentacular creatures whose schtick is to invade the bodies of other creatures, either inhabiting them passively as a passenger or replacing their brain and nervous system in true body-snatcher fashion. In the latter case, they can cast the arcane spells known by the host, providing their own mental stats allow for it (though the spells cannot be refreshed).
They have 4 racial HD and are "LA: -", but they've been approved as a player race - might get stuck with more HD or LA before the game starts depending on the other characters, but that's up in the air for now.
What I'm wracking my brain over is what sort of base class I should start out with. My first thought was to go with some sort of psionic class, as it would allow for manifestation out of bodies I'm tagging along in - inhabiting a body in that fashion only allows for purely mental actions. The minimum of 4 racial HD makes me weep for lost manifester levels, but them's the breaks.
I'm contemplating going Factotum, though (especially if I could replace the Arcane Dilettante ability with some sort of psionic variant), as I'd like the character to be a knowledge hunter of sorts, traveling the planes for all sorts of interesting things. Being a member of either the Fraternity of Order or the Society of Sensation, depending on just how I'd spin the mentality, would be really cool, I think.
