For those without the rule book (Fanog and Zombie Dude) here is how you get your BAB, hit points, saves, etc.....
You can be either a Defense Option or a Offensive Option character. There are no classes in COC d20. Here is what you would get stat wise with each at 3rd level.
Defense Option
BAB +1
Two of your saves will be at a base of +3, and the third at +1.
You get a +2 Defense Bonus to your AC.
Offensive Option
BAB +3
One of your saves will be at at base of +3 and two at +1
You get a Weapon Proficiency Feat (Melee, Thrown, Pistol, Rifle, Shotgun, or Submachine Gun) of your choice.
A 3rd level character will have 3 feats (2 at 1st level and 1 at 3rd)
Hit Dice are d6's with your first level giving you the max possible
hit points.
Starting Sanity is 5 x your Wisdom.
You get (8 + Int Bonus) x 4 skill points at first level and 8 + Int Bonus in skill points per level after that.
You have 12 Class Skills dependent on your Profession. I will work up a list of your Class skills and if you want to change them just let me know.
