Harmonics

Harmonics 1.5.0

Bug Fixes

Fixed 28 broken crafting recipes that were silently failing in Minecraft 26.2 due to outdated ingredient format. The following items existed in the creative tab but had no working crafting recipe in survival:

• Armor: Crystal, Shadow, Astral, Ender, and Frost sets (20 pieces total) — their recipe JSONs used the pre-1.21 object format ({"item": "..."}) which 26.2 no longer parses. All converted to the correct string format.
• Weapons: Ender and Frost sets (8 pieces total) — same format issue.

Removed 45 duplicate instrument recipe files that were cluttering the recipe/ root directory (the canonical copies in recipe/instrument/ already work fine).

Recipe Changes

Crystal set ingredient changed from amethyst_shard to prismarine_shard.
Both the Crystal armor and Crystal weapon recipes previously used amethyst shards — the same ingredient as the Amethyst armor set. This made the two sets compete for the same resource and felt redundant. Crystal now crafts with prismarine shards, which:

• Fits the "Prism Refraction" theme of Crystal gear
• Gives ocean monuments a crafting purpose beyond conduits
• Keeps Amethyst and Crystal as distinct progression paths

New Features

34 advancements added so all recipes are properly discoverable in survival:

• Recipe tab — A new "Harmonics" advancement tab appears in the advancement screen. Each material set (armor, weapon, instrument) has its own unlock trigger: pick up the ingredient → recipes appear in your recipe book with a toast notification.
• Milestone advancements:
  • Harmonics Armorer — Unlock any armor recipe
  • Harmonics Weaponsmith — Unlock any weapon recipe
  • Harmonics Bard — Unlock any instrument recipe
  • Master of Harmonics (hidden challenge) — Unlock recipes from every single material set

show_notification: true added to all 126 shaped crafting recipes — you now get a recipe-book toast the moment a recipe unlocks, instead of it silently appearing.
