I should have posted my other build but ran out of time...
It wasn't a full caster build, and was a bit strange, using things I'm not really up on. but basically it was this

Totemist 2>Sha'ir 1> Avenging Druid 1 > Black Blood Cultist 10 > Geomancer 8

It basically pounced on you with so many natural attacks, that all instigated grapple checks and for every hit, you did damage with all natural attacks for free (every time)

plus the grapple went off, and you could choke hold a grappled creature in to unconsciousness 1-3 rounds, then coup de grāce.

oh and had some spell casting as a 9th level Sha'ir, 1st level druid
