Fiend Folio - Fiendish PrCs - Nifft?

[Drowbane]

Has anyone revamped the 3.0 Fiend Folio's "Fiend of Blasphemy", "Fiend of Corruption", and "Fiend of Possession" PrCs?

Nifft, I'm looking at you!

I haven't looked at them, but my last impression was that they were pretty okay.

What do you see as lacking in their usefulness, implementation and/or flavor?

Thanks, -- N

The other day I was thumbing through my FF and came across those PrCs for the first time in a few years... and I remembered that you posted alot of fixes for Vile Darkness PrCs (and revamped some of the Uber-fiends IIRC)... so I was wondering if you'd done anything for the Fiend PrCs.

Something about the Fiend of Blasphemy's cleric spell progression bothers me... can't quite put my finger on it. Almost seems like they should raise up more like an Ur-priest.

On a related note... where could I find your Vile-Darkness works?
