KubeJS Custom Rarity
Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
KubeJS addon that allows you to create custom rarities.
Create and customize your own rarity types with support for hex colors and text formatting.
Limits:
- Forge / NeoForge: up to 200 custom rarities
- Fabric / Quilt: unlimited custom rarities, available only for 1.20.1
You can apply custom colors using hex color codes and add formatting styles to each rarity.
Available formatting codes:
bold, italic, underlined, strikethrough, obfuscated
Examples:
StartupEvents.registry('item', event => {
event.createRarity('mint', 0x98FF98)
event.createRarity('fire', 0xE25822, bold, italic)
event.createRarity('teal', 0x008080, bold, italic, underlined, strikethrough, obfuscated)
event.create('mint_gem')
.displayName('Mint Gem')
.rarity('mint')
event.create('fire_gem')
.displayName('Fire Gem')
.rarity('fire')
event.create('teal_gem')
.displayName('Teal Gem')
.rarity('teal')
})
