I'm pretty sure i'm right cause i remember from the demo too turn the kobolds too your side u must kill a special kobold but for some reason hes not there was this changed after the demo?

In order to get the Kobold leader to appear in chapter 4, you must do a couple of things in chapter 1, "Tiger's return":
1)  You must choose Jenna as your partner.  This will not work with if you choose Gunther or Zule.
2)  Destroy the Army of the Dead's base (bright green).  Near the haunted gold mine will be three cages.  Break them open to rescue a kobold named Taskmaster 'Rijik', who will thank you.  Finish the chapter.

Once you have rescued Taskmaster 'Rijik', he will appear in your base in chapter 4 and will explain how to turn the kobolds to your side.  Without him, you won't be able to do anything to the kobolds except to destroy them.

Thanks
