Hexer and Hexblade are very, very separate classes. The Hexblade is most definitely not an update of the Hexblade, and no mention has been made of it.
Forgive me, I went and looke up the other two as well, I'm actually close the classes are the same the entry req's changed from maho to tainted, but they have the same class features. Still *sigh* failure.
My... my 3.0fu is weak. ...
forgive...me... *plays dead*
*hops up* You're not on crack though, this type of challenge is what makes us Brilliant Gameologists
researching....
EDIT: Squirrelloid's analysis is great btw more G-fu for you! I see two prc's that maybe be excellently handy.
1. Sacred exorsist
2. Contemplative.
So in this case athiesm make you weaker, choose a god, Kossuth *for example* god of fire, chose fire and earth,
gain turn undead,
Later take sacred exocrist Gain a domain (of your choice from your diety's portfolio.) Actually kossuth really wouldn't work we to take sacred exorcist we have to have either dispel evil or dissmissal on our lists, I'd have to check back and see if they're on the spell list somewhere I'd be afraid it'd be on air and after the sell for earth shugenja well I don't see how we could give that up.
But essentially we've picked up two levels and two huge gates to power. Turn and A domain heck maybe 2 if you can' find anything better
