First off, not too much effort is going to be put on this forum post. Sorry im a noob when it comes to this.-Well most players my stats have finished quests. Not too hard to do and earning those few extra xtals helps out. Attack is mainly needed for those. For hansels it is a bit harder for us to complete them quickly. So i suggest that you make quests specifically for spies. Scouting enemy forces, assassinating the witch, stealing wizards gold etc. Another way to earn a few extra xtals.
