<a class="postlink" href="http://www.d20pfsrd.com/gamemastering/other-rules/creating-new-races">Pathfinder has built rules for making races Netjak.</a>Ambrose mentioned it earlier in the thread but the link broke. Poke around with those and see what you can come up with.<br/><br/>Edit: Unless I misread you and you already are using them. In which case I'd recommend getting a rough draft going with null or placeholder values to be budgeted later for effects not covered in the rules.
