This mod replace the items list of Elder Melder such as plates, gems, decorations, and streamstones. You can check the new items list in media tab. It is impossible to add an item slot (too many bugs occurred), so I edit original item slots. This means so many items of Elder Melder will be removed. Therefore, you must check new items list first. This is cheat mod so USE AT OWN YOUR RISK.

In plates and gems, it is same as original.

In decorations, you need 3 decorations to get the decoration you want. There are 4 grades (1000, 500, 300, and 100 research points). This is divided into drop rates of decorations. For example, the drop rates of 1000 pts decorations are all same. Other things are similar to this, too. I cannot add all decorations because there are too many. So I chose some decorations in popular.

In streamstones, you need 8 streamstones to get the streamstone you want. There are 2 grades (warrior and hero). Please refer another mod named "Streamstone Exchanger in Maka." This mod is incompatible to that mod.

In merchant, five materials (whetfish pin, dung, two extracts, and voucher) will be added. This is because the many items of Elder Melder will be removed.
