Treasure Maps: How can you find treasure maps? When you walk through the world of Tamriel, you come across chests that are scattered throughout the Arena. Here you can find the treasure maps inside. Also, when you kill crowds of enemies, you can find them on their person.
You can trade or sell your treasure maps if you don’t want to wander around trying to find them. When you open the map, it looks like a drawn sketch, each part of the drawing is a reference point that you can use to calculate the location of the chest. On the map, look for something that is rare or unusual as a place to go. When you get a treasure map you should try to do it right away, there is a limit to the treasure maps you can carry.
The items you can get are very helpful especially when you are just starting out. When you find the location, it normally looks like a pile of mud, no need to dig, just click on it. Hope this has been helpful to you and good luck in your search!
