I've noticed bloodlines work really well with binder/ardent. Can Illumian progress Ur-Priest at all? Also, it seems that with proper investment in spells/powers, a one level dip is all that's really needed to max out incarnum (or at least be really really good at it). And when you can auto-persist things...Incarnum Apotheosis seems really sexy. If Illumian can progress Ur-Priest though, I can get it all, 9th arcane and divine (my usual Ur-trick), full meldshaping, 8th level vestiges, 9th level powers, without a bloodline (though that may end up being more optimal, ironically).
Yup, illumian (improved sigil) +bloodlines works really well with binder/ardent! Then use the psionic variant of anima mage. It's not my idea, I read it on the CO boards. Throw in practiced manifester and improved binding for early qualification tricks to get into animal mage if wanted.
This part I am not so sure of, but Illumian +bloodlines should also boost initiator levels. To get level 9 maneuvers, you need to have IL of 17. Illumian give +3, 3 levels of bloodlines also gives +3. So that means you only need to get an IL of 11.
IL for multiclassed chars = half of total char levels PLUS the IL of any initiator classes. So a level 20 multiclassed character with only 1 level of crusader has an IL of (20/2 + 1) = 11. Just nice. However, I don't think you can take 9th level manuevers at crusader 1, in that case, you will need to take 1 more level of crusader (at character level 18 or higher) and use that level to learn the level 9 maneuvers.
If it all works out,
Illumian with improved sigils,
bloodlines 3/ardent 1/binder 1/anima mage 10/xxx 3/crusader 2
Should get 9/9/9, with 3 free levels for whatever else you want. Ur priest maybe? No restriction for Illumians taking levels in Ur priest. Or totemist... 9/9/9 + 2
Also for the ardent, have a erudite cohort with the convert spell to power ability Psychic Chirurgery converted divine/arcane/druid/paladin/bard spells to you. 9/9/9 + 2 + 9/9/9/9/9. If your gm only allows epic erudites to convert level 9 spells, ask him if he's ok with allowing you to find and pay an epic level NPC erudite to do it (just the level 9 spells).
I am currently trying to see if I can add in Illithid savant and gestalt the whole damn thing...
