Are there any existing conversions for the 3.5 Archivist, the divine caster. Also how do you use Tome of Battle in your games?
There are a few for the ToB if you do a forum search. Personally I'd buff them up a bit, especially around the dead levels if only to make it more interesting, and change the key skills to match the new skills in PF. Not having to put every skill point into your key skills isn't a bad thing.
search "give me a base class i can design" by smilodan, he did that conversion wonderfully.
