Quester Master
Very rare1.2%This achievement requires you to reach the max rank, 10, with the Knights Guild INC. As you probably know, you increase your rank by completing quests. So, logic would dictate, all you need to do to get the achievement is do a LOT of quests, high rank ones preferably. You'll get it eventually just going about the grind but, just as a tip, you should probably set your days pretty short if your going for this one, as you can only complete one quest per in-game day.
