Archer of the Month

For this you will need the "Elite Ranger" ability so will require at least 7pts to get it. Once you have it, its as easy as getting to a high vantage point pick your target leap off the ledge and make sure you get a head shot. It can be a little tricky depending on the height of your ledge for the time you spend in the air, but pick a small group of enemies just incase and you will be sorted =]
