LegendaryItem

Advancements — 36 Total

• Full vanilla-style rarity ladder (Common → Legendary), reorganized so easier achievements appear before harder ones

 Stability & Compatibility

• Ported from Minecraft 1.21.11 to Minecraft 26.2
• Fixed numerous mixin crashes from API/mapping changes between versions
• Fixed chat messages occasionally showing the wrong rarity after crafting.

Anvil & Grindstone

• Renaming items at the Anvil is now fully free — keeps your custom name while preserving the rarity color
• Fixed item names not updating after material upgrades (e.g. Diamond → Netherite now correctly shows "Legendary Netherite Sword" instead of keeping the old name)

Rarity Logic — Progressive & Logical

• Rebuilt probability tables into a clean linear progression: Wood < Stone < Copper < Iron < Gold < Diamond, each tier slightly luckier than the last
• Netherite reworked: no longer rolls its own rarity — upgrading at the Smithing Table now inherits the rarity of the Diamond item, plus 1 random bonus stat (50% positive "Netherite Surge", 50% negative "Unstable Fusion")
• Highest rarity always wins when combining items — works in crafting (2x2 and 3x3), Anvil, and Grindstone
• Stats and rarity are never lost — preserved through renames, repairs, and material upgrades
