It converts horribly to D20 no matter how many times you try it. The corrupted warrior or whatever it's called, is adapted from the Maho Bujin prestige class presented in OA, as is the Blood sorceror...or whatever. It was the Maho Tsukai.
That, in a nutshell, is the problem with the Taint mechanic. It's for a completely different rpg system.
