Sorry. Can't help much unless he allows 3.5 stuff. It's my specialty.
But, if he does allow you to use 3.5 go to the
EVD.
Get the Weapon Section, read up on WSAs, Necklace of natural weaponry, Gauntlet handbook, and Extrapolated WSAs.
Get a Necklace. Get Ancestral Relic feat. Make a customized NoNW to your specific needs.
Then pick up the Augment section of the EVD. Chop off your arms and get warforged construct arms for the slam attack. Get Beast Claws feat to add your slam damage to your natural attacks. Used NoNW to add damage to your Unarmed Strike AND your slam attack so the damage of both are doubled.
I would like to point out very little of this depends on your build.
Check Back in about a week or two when I put out the Improved Unarmed Strike feat Handbook, to be followed up with the natural attack feat handbook.
