Turn Minecraft Into a True RPG Experience

Sol’s Item Rarity Mod adds a fully customizable RPG-style rarity system to Minecraft.

Every weapon, armor piece, and item can have unique rarity tiers, stat bonuses, animated visuals, and persistent attributes.

  • Randomized loot progression
  • Scalable item stats
  • Works with ALL mods
  • Fully configurable JSON system
  • Multiplayer-ready (server sync supported)

Key Features

Dynamic Rarity System

  • Weapons & armor roll random rarity on first use
  • Items store rarity using NBT (persistent per item instance)
  • Same item can have different rarities

Visual Enhancements

  • Animated chroma item names
  • Rarity-colored inventory & hotbar borders
  • Multi-layer UI effects (glow, bevel, sparkle for high tiers)
  • Tooltip borders match rarity

Attribute Scaling System

  • Items gain stat bonuses based on rarity
  • Fully configurable multipliers
  • Auto-applies stats to all weapons & armor (including modded)

Fully Configurable

  • JSON-based configs for:
    • Rarity chances
    • Fixed rarities
    • Attributes
    • Set-based items
  • Works with any mod using modid:itemname

Multiplayer Support

  • Server configs auto-sync to all players
  • /sr reload updates everyone instantly
  • No client-side desync issues

Rarity Tiers

Tier Multiplier Effects
Common 1.0x No effects

Epic 1.5x Strong chroma
Legendary 2.0x Animated borders
Mythical 3.0x High-tier visuals

How It Works

Random Rarity (Weapons & Armor)

  • Rolls when first held
  • Stored permanently in NBT
  • Higher rarity = stronger stats

Fixed Rarity (Items & Materials)

  • Uses built-in + custom configs
  • Ideal for rare drops, boss items, and special materials

Priority System

Rarity is assigned in this order:

  1. SetID fixed rarity
  2. Custom / internal fixed rarity
  3. SetID rarity pool
  4. Item rarity pool
  5. Auto-detected weapon/armor
  6. Default fallback

SetID System (Custom Loot)

Create boss drops and unique gear:

/give @p minecraft:diamond_sword{SetID:"boss_drop"} 1

Supports:

  • Fixed rarity
  • Custom rarity pools
  • Custom attributes

Auto-Attributes

All gear automatically gains bonuses:

  • Swords → Damage + Speed
  • Armor → Health + Armor
  • Boots → Movement Speed
  • Shields → Knockback Resistance
  • Works without config
  • Scales with rarity

Sol’s Relic System Integration
