The first 2 expansions of the wallet are sold at the pawn shop. To expand the wallet further, you need to fuse your wallet with a turquoise stone or a Ruby Stone.
Both of these items are found in silver chests in the Waterfall and Desert areas.
To be able to find them easier, you need to upgrade the item Treasure Finder.
To upgrade Treasure Finder to Silver Treasure Finder:
- Find Silver Ore by battling monsters and defeating them in Dimore Cave.
- If Dimore Cave is too dark to explore, battle, and defeat jellyfish monsters at the Palmtree spot (Beach). Fuse the empty lantern with a light crystal sold in the alchemy shop to make a lantern. Equip the lantern to explore dark places.
- When you find Silver Ore, fuse it with the treasure finder to make it Silver Treasure Finder.
Most Silver Items can be upgraded to gold by fusing them with a gold nugget. Most gold items can be upgraded to Mithril by fusing them with a Mithril. The higher level you fuse the Treasure finder, the easier it is to find rare items.
Using the treasure finder.
Equip the treasure finder and defeat monsters. Every time you defeat monsters, the treasure meter fills up. When the meter is full, it will start changing color to red. During this time, your chances of finding a rare treasure increase with each battle. It will guarantee you find a silver or a gold chest. But you must not leave the area or escape battles because the meter resets. Keep the meter high as long as possible; you will find a rare treasure. Use an Energy potion if you have to.
