Original General Dungeon Fighter Thread

Well, the good news is that you're so early on that you could still salvage your build and make it still work out. It obviously wouldn't be the optimal build but that shouldn't stop you from killing well enough. There are two websites that are generally used for planning out your builds:

http://oldmanclub.co.cc/asps/ - this one is better in that it's completely up-to-date with the latest patch

or

http://www.aradsociety.com/planner/ - this has the advantage of letting you see what the skills do and how they scale as you level though it's not right on some of the requirements or their SP costs

As a fmech as long as you have max G-series you should be alright, I do suggest looking around at that site Mark mentioned though to give you a better idea of how to build yours.
