Using MMOItems API you may register custom stats as complex as abilities or item restrictions. The first thing you will need to do is define a class which extends `DoubleStat` which is an abstract class with many functions, we will go over what each does, but first let's deal with the ItemStat constructor you need to call.
```super("GEM_SOCKETS", new ItemStack(Material.EMERALD), "Gem Sockets", new String[] { "The amount of gem", "sockets your weapon has." }, new String[] { "piercing", "slashing", "blunt", "offhand", "range", "tool", "armor", "accessory" });```
