Custom Rarities

This mod allows you to create custom Rarities for your items via json datapack. Rarity json files go in data/custom_rarities/rarities/
and the json should look something like

{  
    "name": "amo:amazing",  
    "color": "#ff80dd",  
    "items": [  
      "minecraft:diamond_sword"  
    ]  
}  

The mod only supports hex colors, as it is convenient.
You can add rarities while in game and use the /reload command to see them, but editing or deleting your custom rarities require a restart due to how Minecraft handles rarities. It may be fixable but it would require a lot of workarounds and possibly some incompatabilities.
