This job is one of the easiest jobs to Master (which is a good thing). Some castles, dungeons, and caves require you to have a Geomancer in your party. You will come to points where there are hidden trap doors and floors that hurt you when you walk on them. If there is a Geomancer in you party, you will be warned before you accidentally fall into a trap door, and walking on damage floors will do no damage. Also, the !Earth ability is fun to use. Try using it while in different terrains.
