RarityCore

RarityCore Ver.13

Beta is currently only released for 1.20.1. Some features may be buggy or poorly optimized — please stay tuned for future improvements.

New: Rarity Visual Customization

You can now customize colors, textures, and visual toggles individually for each rarity tier! The configuration file is located at config/raritycore/RarityClientConfig.json. It supports separate settings for tiers 1–7:

• Color — RGB format (e.g., #FFCC00), used for tooltips, item names, and the programmed border.
• Texture — Custom border texture path.
• Individual Toggles — Each tier has independent controls for tooltips, border rendering, and name coloring.

The master switch in client.json still takes precedence — if it's off, per-tier settings will not apply.

New: Tag-Based Mass Rarity Assignment

Don't want to assign rarity item by item? The new config/raritycore/TagRarity.json lets you use Minecraft's tag system to assign rarity in bulk.

New: In-Game NBT Tag Rarity Control

With enableNbtRarityControl enabled in server.json, items can control their own rarity appearance directly via NBT tags.

This tag has the highest priority, overriding all other rarity configurations. Perfect for custom content or cross-mod integration.

New: Iron's Spellbooks Integration

Spell scrolls now automatically gain rarity based on the level of the spell stored within them. The higher the spell level, the higher the rarity!

Refactor: Full Overhaul of Edit Mode

Edit Mode is no longer just a simple "click an item to change its rarity". Ver.13 introduces two new modes:

Normal Mode (default) — Works as before: click an item to write to FinalRarity.json. rarity=0 means "no rarity".

FullMatch Mode — Click an item to automatically generate an NBT-matching configuration! It uses all current NBT tags of the item as matching conditions, making it possible to distinguish items with the same name but different data (e.g., different potion types, different enchantments).

Numerous new commands have been added, and there's even a GUI panel!

Improvement: Enhanced Export Command

Added /raritycore export rarity <tier> to export all items of a specific rarity tier.

New: KubeJS Support

Do you have KubeJS installed? You can now control rarity using JavaScript:

Optimizations

Many areas have been optimized — overall, it's smoother than before!
