Easier experience
If you are a Warrior and higher than level 75, use a Magic Mace, and have an Orb Of Holding, go to Drear Valley that is east of Monmouth Teleport. When your there, attack any Aegiscians you come across. When you enter the combat cloud, use your Orb Of Holding on the Aegiscian. This will hold him in place for five rounds. Then, start to attack him. You should kill him fast, before he can move and get yourself a lot of experience points.

Wilderness shops
When your out traveling the land, you may come across a tent that houses a "wilderness shop". This is a good place to fix your armor and weapons, and recharge your orbs. But do not buy from these stores. They charge far more for their items than the regular stores in towns. They will also pay less for items so do not sell to them. Also keep your sellable items until you return to town.
