There is a scouting patrol mission on the farm that will provide you and everyone else there with a temporary buff. This buff will be removed as soon as you leave the farm, but while you are there it will make your character glow blue and provide you with super jumping abilities and increased speed for the duration of your stay on the farm. The video above will show you a super speed run on how to get it. It will likely take you much longer since you won’t be able to jump like this.
There is no other permenant reward or loot for completing this quest, it is only for glory and honor amongst your peers on the farm. Maybe in the future something will be added to this to make it more worthwhile.
