Its just an observation, but the guy in the screenshot is not using auras wisely.
first hes got a defiance merc, and hes using the armor with the thorns aura.... thats counterproductive, monsters have to hit you to get damaged by thorns.
Also I see he has the decrep curse on his right button.... So he further makes thorns worthless by slowing monsters down and halving their damage.
If he wants to use thorns he should be using a prayer merc. If not it should be a might merc.
