I just want to say that I almost managed to do that when i cleared part of the first area and the plase in Sunken Temple where ther is a basin where 3 mobs areand the circular balcony with the steps leading down there, I got my water elemental out, and use its ranged frost nova and focused fire on one mob and it died and my pet is taking hits and it died, I then cold snapped and used it again, and focused on the other mob while kiting them both, i am at 55% health and I had to use my instants when the elemental died and my ice barrier only last 3 or 4 hits and the other mob died, so im at 700hp with the last mob at 80%, ice blocked for my cooldowns to reset and my mana is almost depleted when ice block finished, i frost nova and used evocation and tried to kite the last mob. I nearly took it out until it critted me for 450 while it is at 10% hp.
So thats my story, i didnt know why i tried to solo ST at my level but i managed to get 3 BoE greens and a BoE blue Mistwalker boots.
