My current DM has been running a great d20 modern campaign for the past few weeks, but he's informed us that he's going to be making a switch to the Pathfinder system sometime in the near future. We're all attempting to convert our characters from their current builds to something similar in Pathfinder, but I'm having a lot of trouble rebuilding my Techie. The only class I've found that's even remotely similar is the Artificer, but even that is heavily steeped in magic and magic items as opposed to machines, or even engineering.
Are there any alternative classes, or builds, that would support someone involved in building machines, working with technologies and things in that vein? (It doesn't even have to be very competent in combat, a support class would be just fine.) Or does it look like we'll have to sit down and come up with a custom class ourselves?
Any help would be great!
