Avalon:
Go back and give me a book and page numbers on all those classes please. I've been holding off on oking your concept cause I don't have time to track all that down.

Ok I hate to say it, but Monster of Legend does not compare in any way shape or form to Feral, or to Half Fiendish/Celestial. Some of the abilities may come close, but some of the other abiltities you can choose are way overpowered, like the 5 levels in spell casting you are going for. The finishing blow is that fact that its stats get +34 points with no negatives. I'm not going to allow it, sorry.
Permanent spell effects (and I'm assuming your talking about the Permancy spell chart in the PHB) are fine with me, just let me know what things you want ahead of time please.

Nightbreeze:
I notice you took Iaijutsu Master 20, when its only a 10 level class. Just to save you from asking, I am not allowing the epic variant from the wizards boards. If you want an epic version, I'd say the progression would just be a bonus epic feat every 3 levels.
Walking Dad:
No negetive level stuff please. That would be pushing you back into the realm of a caster.
