I am at level 27 and I have beat Taskmaster Djal in Karanahn Barracks twice and still can't get anywhere. It keeps wanting me to fight again and again. What can I do to bet them and move on?
Before you fight Taskmaster Djal, you should be fighting Kiwu. Kiwu is located in a small alcove/area near the Taskmaster. After you defeat Kiwu, you walk up to the food table that is set up in his area, and you press "x" to pick up a "sleep potion" for Taskmaster Djal's guards.
So now you go in to fight Taskmaster Djal, and all of his guards are gone and he is alone. When you defeat him, he gives you a key to return to Salid (?), so you can free the slaves.
When you said "what can I do to beat them...", it sounds like you didn't defeat Kiwu first.
