[chaincomplex]

[EDIT]- this build would benefit greatly from the LA reassignment.

Go with +2 LA.

Spellwarped

Go with +2 LA.

Thri-Kreen

Go with +1 LA.

Thanks, and some more pertinent questions;
Is permanent int increase retroactive?

Yes. This isn't rules faithful to D&D 3.5e but timing Int increases for a build is just annoying bookkeeping that doesn't add to the game. Pathfinder fixed this, IIRC.

My query was overlooked but partly answered. I still need a definitive answer though.

Are officially WOTC approved second party sources allowed? I am thinking of mimir.com and athas.org as sources for 3.5 material for Planescape and Dark Sun material. Just for the record, they would be ideal sources of material for you to use too, as a DM.

Sorry about that, got lost in the mix. I wasn't aware either of these were considered "2nd-party". Unless you can show me otherwise I'm going with no. As I recall we only got 2nd-party Dragonlance and Kalamar stuff.
