Background:

You have 102 points that you can put into any one of the first 7 catagories. This determines what your character is like. If he is a brute then he will have a good strength score, while if he is a genius then his intelligece will be good.
Be careful to have at least a 10 in any one score or else you will suffer penalties. Someone with a 8 wisdom is insane, but he could have a 25 intelligence and be a genius. While someone with 25 wisdom and 8 intelligence would be a simpleton, but be very knoladgeable in the ways of the soul.
Now your Base attack bonus is determined by your strength score, equiling your strength score divided by two minus 5. Then your marksman is determined by your base attack bonus plus your dextarity using the same formula to get the bonus. Your swordsman just uses your strength bonus twice.
Skills determine what it is your character can do. Your intelligence determines how many different types of things you can do, and allows you to craft better items. To determine if you craft an item you roll the d20 and add your Intelligence bonus (Intelligence/2-5=bonus) and then add 5 if you are trained in that skill. This determines your success or failure in the attempt to craft your item, if you beat a set DC then you sucessfully craft it, if you get lower then you botch your materials and fail in crafting.
The weapons and nanoids entrys are where you put the statistics for whatever weapons or nanoids you currently have.
