I understand in theory but seriously need step by step on how to do it. It has to be in order but do you have to slash at thief #1 then to an inferno on thief #2 or do you have to slash over the 2 of them at once and then do inferno over them both? As soon as I do one stroke they take off, seemingly unharmed. Should I make both brush strokes at the same time? Seems I've tried everything but they always run away.
