Level 65 - After I soloed Kallis, I was pretty curious to see if I could do the same with Gkrean and Semkak. The only things I were really worried about were gating and heals. Gkrean was a total pushover, though. I had some difficulty splitting him from the room initially, but it was smooth sailing aferwards. He didn't even attempt to gate and I didn't see him land any heals, so I thought it was safe to assume that these guys blew all their mana during pulls.
