yeah, I'm reading that and the handbook. The extra Pathfinder and dragon options are where i'm looking for the most help. I'm unfamiliar with artificer because I'm used to playing Factotums. I'm kind of lazing out and I figure there's some people here who already have such a build.
Ah, you want help mostly with the pathfinder material. Well, I can't help you too much there.
However, I did take a look at some of the pathfinder traits and Eldritch Smith seems to be the best since it gives a 5% discount on all metal or stone items (including metal headed weapons with non-metal parts). However, it is a dwarven trait, so unless you can include in your background that you were originally a dwarf who got transformed into warforged (since you still qualify for your original race's traits even if you change race), it doesn't help you.
Edit: I missed Hedge Magician the first time so that would go great with Eldritch Smith. I also seem to remember a rule that allows one to make wands out of alternate materials, I'll have to look it up.
