I went to the Skrag Caves, thinking I was going to fight with a team, but they couldn't get in the battle for some reason. Anyhow, I fought all 5 sentries of the chieftan using my 6 horns and my dragon and I defeated them which thoroughly amazed me. But, when I clicked to go fight the chieftan, it said I had to fight the sentries first (again). I thought when I defeated the sentries, I would be able to fight the Chieftan. Isn't that how it is supposed to be? Someone help me understand what happened please.
