PDF here. This is a splice of the Tome of Secrets Artificer and Eberron's Renegade Mastermaker with a few extras of my own design thrown in for good measure.
Please tell me your thoughts.
Noticed some errors in the Artificer class and cleaned them up. The old download is gone, use this link to grab the cleaned up Artificer.
I haven't read either of the classes you're blending...I really need to get Tome of Secrets, I guess. It sounds like that book needs some tidying up, which historically I've been reluctant to do...except that I have a pile of 3.0 and 3.5 books and I'm doing just that to make them balanced for Pathfinder, so whatever.
I'm not sure how balanced it is at high levels...my first thought is that it might be kinda underpowered, of all things...but the cheap access to items may have me way off.
The only real helpful thing I can say is that the base attack bonus progression doesn't match the hit die. With PFRPG, they really tried to get them to match up, and the "good" progression normally calls for a d8. Given the overall limit to the spellcasting power and the physical class features (Battle Fist, Damage Reduction, Steelplate Skingraft) it seems like setting the hit die to d8 would fit right in.
