Hi! Would it be possible to add the compatibility with LevelZ by making some changes on the material class for Rose Gold?

Here are the suggestions made by the developer of LevelZ:

• The dev has to change the material to an enum
• The dev can override the toString method inside his material class like here: https://github.com/GitPois1x/DragonLoot/blob/master/src/main/java/net/dragonloot/item/DragonToolMaterial.java

I also put the issue here to know more if needed:
