Tough As Nails: A Curios Expansion

Tough as Nails: A Curios Expansion Forge — Minecraft 1.20.1 — v3.1.1

What's new since 1.2.1

A long list of fixes plus the multi-loader rework that brought a Fabric/Quilt build alongside the Forge one.

Bug fixes   • Universal Thermal Insulation curio works when equipped (was a     silent no-op in 1.2.1 — onEquip was calling disableModifierForPlayer     instead of enableModifierForPlayer).   • Universal Thermal Insulation tooltip now matches actual behaviour     (HOT -> WARM, ICY -> COLD; previously overclaimed "completely     inhibits all forms of temperature damage").   • Temperature modifiers register exactly once at mod init instead of     re-registering on every player login (could stack N-fold on     long-running servers).   • Per-player UUID maps clean up on logout (slow memory leak on     long-running servers).   • Firoze brewing recipe now uses Regulation Crystal as catalyst     (previously expected a Glass Bottle, which never matched).   • Regulation Crystal is no longer enchantable (a stray     getEnchantmentValue override was returning 32).   • mods.toml dependency cleanup: removed a duplicate toughasnails block     and a dead curios_api block; pinned minimum versions for TaN ([9.2,))     and Curios ([5.14,)) so version mismatches give a clear error     instead of a runtime crash.   • Curios tag JSON files now use a proper boolean for "replace".   • 3.1.1 hotfix: resolved a startup crash from CuriosIntegration     registering on both event buses (3.1.0-only regression).

New features   • Choose your slot system: Curios OR Accessories. The mod auto-detects     at startup and registers items into whichever is installed.     Accessories takes priority when both are installed, so you can't     accidentally equip the same insulation twice.   • Items decoupled from Curios: a Forge user with only Accessories     installed (no Curios) loads cleanly. The slot-system code is a     soft dependency.   • Existing crafting chain unchanged: Regulation Circuit Shard ->     Regulation Circuit -> Regulation Crystal -> Thermal Insulation     curios. Firoze fluid still placeable; brewing-stand recipe still     works (potion + Regulation Crystal -> Firoze Bucket).

Required dependencies

• Minecraft 1.20.1   • Forge          47.x (>= 47.4)   • Tough as Nails >= 9.2   • Glitchcore     >= 0.0.1.1 (Tough as Nails depends on this directly)

Optional — install ONE for the curio slot

• Accessories  >= 1.0.0-beta48+1.20.1   (preferred when both installed)     OR   • Curios API   >= 5.14.1+1.20.1

If neither is installed, the items register but can't be equipped into any slot — they sit in your inventory.

Java 17 required.
