I think it is way too hard. I tried already, I was only on the Krokosphinx at the time, so I had to get a friend to get me into Chelsea Court. I had a fire elemental minion and I still couldn't beat Nimah! She has 5,000 health and a 1,750 health minion. I didn't even beat the minion! Please make this easier KI.
I'm also hoping the Fire minion quest is eaiser than the Ice minion quest!
