I took it from Fallout though. In that marvelous game, every third level you got a perk (unless you picked skilled in the beginning, but only idiots do that...). On the first level you only got not too good perks like: (what percs did you get again? What are they called?) Awareness. You get more detailed info when you examine enemies (might be quite good, but not nesccesary) and swift learner (+5 % when earning experiencepoints. It's even moore useless than wisdom in DD). You get these on level 3. On level 6 you get little better perks (you can still pick lelev 3 perks though) like: More chritticals (the name speaks for itself) and educated (+2 skillpoints when earning a level). On evel 9 you get yet better perks (you can still pick from the lvl 3 and lvl 6 perks)like: Bonus rate of fire (you fire quicker with guns. Since I'm a gunman I allways pick this one. The rest is pretty unimportant on this level...) and better chrits (allso speak for itself. With sniperperk this can be pretty usefull). On lvl 12 you get Action Boy (get one (what are they called?)Actionpoint every round ie you moove faster in combat), on lvl 18 (there is only one lvl 15 perc, so you pick one lower lvl there) you get sniper (you never get to lvl 18 though...) (use your luck roll in order to decide if you get a chrittical hit. If you have 9 in luck, you have 90 % chance to get a chrittical <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />).

PS if you haven't played Fallout+ Fallout 2, do it! They are two of the best games I've ever played! DS
