I know a lot of people have never compounded an item before, so I made this tutorial to explain how to compound, and what it does.
For a list of all the compound materials, go to
http://www.mymmogames.net/wiki/index.php/CompoundThere are other *Abnormal* attributes you can compound too (Critical Rate, Block rate, etc), but I dont know much about those.
Compounding an Equipment will add various stats to it. This includes AP, AC, DX, MP, MA, MD, WT, DA, LK, HP, DP, and HV
Elemental Attributes can also be added to weapons for elemental damage and to strengthen some elemental skills
You can also compound Elemental Resistance. They minimize the elemental damage taken from monsters
First bring your compound materials, the equipment you want to compound, and money to Alchemist Nate in either Desert Town - Paradise, Aquarius, or Carbigal. *Elixirs are optional for increasing the compound value
If you right click on your equipment, you will see a list of compoundable stats.
You can ONLY compound what is shown in that list. It will also show you how many slots an item has ( The more slots, the more you can compound) if any.
Place the equipment on the slot provided and there will be a summary of what can be compounded and how many times you can compound it.
Next place your compound material on the first slot at the bottom. It will show you the value of the compound ( How much it'll add) and 2 numbers will appear in the slot with the material. The black number represents how much of the material you own and the red number is how much you need to compound your equipment. Your fee will appear at the bottom right corner. Once you are ready to compound, press the go button
