About this Mod
A complete tier and reforging system for Minecraft and other mods
This mod completely transforms the equipment experience in Minecraft by adding a tier system. Every piece of equipment and every tool can roll unique attributes, both positive and negative, creating endless customization possibilities.

⚔️ Tier System
Equipment is now classified into 7 tiers, each with its own characteristics:
Common — Basic gear, often with strong negative attributes
Uncommon — Modest improvement, balanced between positives and negatives
Rare — Positive attributes are more common, negatives are light
Epic — Positive-only attributes, moderate impact
Legendary — Powerful, highly sought-after attributes
Unique — Extremely rare, high-impact attributes
Mythic — The top tier, Reforge-only, exceptional attributes
Gear dropped by mobs or found in chests already comes with a tier, and traders are influenced by their level and your luck to offer better items.

🔨 Reforge System
The Reforge Block lets you reforge equipment, with a chance to improve its tier:
Customizable XP cost per reforge
Luck shown on-screen, displaying success chances by tier
The weapon’s tier is visible during the process
Ingredient requirement tooltips for reforging
Support for custom JSONs — create your own equipment with your own attributes
Player Luck directly influences results by lowering the weight of bad tiers and increasing the odds of better tiers.

💥 Improved Combat System
Critical Damage — An attribute that modifies vanilla critical damage multiplier (from 1.5x up to 5.0x)
Critical Chance — Every attack now takes your crit chance and crit damage into account
Tiers for Spear and Mace — New update weapons get full support

🎨 Visual Customization
Tier borders and ornaments — Can be toggled on/off
Detailed tooltips — Show requirements, attributes, and success chances
Mythic tier (aqua) — A new exclusive color for the rarest tier

⚙️ Dynamic Attribute System
The fixed attribute system was replaced with a JSON-based roll system:
Each tier has different weights and chances for positive and negative attributes
4 JSONs per tier for more variety
Datapack custom JSONs work alongside the mod’s JSONs
Option to disable the default JSONs and use only your datapack
The chances table details exactly how many attributes each tier can roll and the expected impact. Exemple to json common_tool_1:
