This is a Quick and easy strategy for killing Helos the Minotaur King in Stormcleave without getting touched.

I was running with a group through stormcleave last night and when we got to Helos the minotaur I noticed a ledge close by so I decided to try and get up there.

All you have to do is when you are walking towards the minotaurs turn right and stay against the wall. You will come up to a ramp. Just run up the ramp and have one person go pull the minotaurs. Once you get agro then join your party members up on the ledge and fire away.

This is the same type of trick that people used in redwillow before the nerf. It works well and Helo can be tough especially once you start increasing the difficulty of the quest.
