Reward: 200 Renown, 900 Gold.
After doing the Attack/Protect Orchard Farm gold quest you can once again face Whisper, this time taking part in Hobbe killing contest. The person who kills the more Hobbes during the time limit wins. Easy as that.
Keep in mind, that Hobbe mages are the least resistant to damage and try to focus on killing them. Try to watch Whisper fight, as sometimes you can finish off an enemy she has wounded before, thus making sure she doesn't get any points at all. Just keep your eyes open and try to watch the whole battlefield to know which Hobbes are already weakened.
