The primary reason for the changes to the Treasure Map system was the great number of maps being stored.

The new Treasure Maps now have a 10 day timer. You now have 10 days to either, dig up the treasure or place the map in the new TMapBook.

The new TMapBook is craftable. It requires Inscription 94.1 and Lockpicking 60.1 skills to craft. You need 5 blank maps, 4 leather pieces and 2 White Pearls to craft the book. Each book stores 32 maps. It stores either decoded or non-decoded maps. Decoded map locations can be viewed from inside the book. The TMapBooks can be carried in your RuneBook Pouch. You can name the book same as many of the special books.

There are also some maps that you cannot see the location of the treasure. When you view these decoded maps you will get the message: "This map is Secret. Only a Genie can read the invisible ink herein." To get to the spot with treasure, you must to use Magic lamp. These maps cannot be used by anyone other than the decoder. Should you try to dig the treasure you WILL succeed, BUT you will not be able to open the treasure chest as it was coded to open only for the decoder.

Genie maps will usually show up as Red text in your T-Map book to let you know that they will need a Magic Lamp to use them. There will be some that are surprise Genie Maps too, so keep that in mind when you have someone else decoding for you, if they decode one of these they will be the only one that can get that treasure for you.
