Okay, I think this works. I know this build spits in the face of fluff, but hell, this is TO hardcore at this point... Prestige classes might need rearranged, but I'm almost positive this all works. This also assumes you have some divine <=> arcane tech.

Spellthief 1/ Bard 1/ Ardent 1/ Wizard 1/ Knight of the Weave 1/ Ur Priest 1/ Shadowcraft Mage 3/ Nar Demonbinder 1/ Sublime Chord 2/ Ultimate Magus 7/ Tainted Scholar 1Gets 9s with Sublime Chord. Is Tainted. With bloodlines, before items,
CL 787.Magic Mantle is stupid transparency means ML=CL right? Take that one feat we talked about in my Mind Mage thread, and now your Illusion
CL 1574. Bill Bisco, your wish is my command.
In this build,
+1 CL equates to +71CL. ((((4+1)*2)+1)*2)+1)*2)+1)*1.5)+1)
Assuming the best possible inturprutation of Greater Comsumptive Field(that it's *1.5
each caster level, then you hit ~8000. If you get items for +2 from items you hit 9091.
How To:
[spoiler]1. Take a Spellthief level and take Master Spellthief.
2. Take levels in prestige classes that grant spellcasting who have special CL rules (KotW, NarD, and SC are great because it's full addition, UrP (1/2))
3. Get 9s.[/spoiler]

On illusion spells you hit 2524. Naked. Formula for adding a single caster level is (((((4+1)*2)+1)*2)+1)*2)+1)*2)+1)*1.5)+1)=
+143. Greater Consumptive Field puts it in the 8000s.
