AutoSwitch Enchant

Automatic tool switching based on enchantment rules for Minecraft 1.21.10 (Fabric).

Features

• Automatic Switching — the mod automatically selects the right tool when you start mining a block
• Enchantment Rules — configure which enchanted tool to use for each block
  • Efficiency 1–10 (supports mods with levels above the vanilla maximum)
  • Silk Touch
  • Fortune 1–3
• Smart Haste Awareness — rules with the considerHaste flag only activate when the Haste effect is active, saving tool durability
• Tool Type — choose which tool the rule applies to: pickaxe, shovel, axe, hoe, sword, shears, or any
• Instant-Mine — the mod calculates mining speed accounting for Efficiency, Haste, and Mining Fatigue, and picks the tool with the minimum level sufficient for instant mining
• Rule Priority — Silk Touch > Fortune > Efficiency
• Tool Return — optionally switch back to the previous hotbar slot after mining
• Configuration Profiles — create and switch between multiple config profiles
• Base64 Import/Export — share your settings with other players via a Base64 string
• Minecraft Keybind Settings — two reassignable keys in the "AutoSwitch" category:
  • B — open the config menu
  • H — toggle the mod on/off
• ModMenu Integration — access settings through the ModMenu mod list
• 12 Languages — EN, RU, UK, DE, FR, ES, IT, PL, PT-BR, KO, JA, ZH-CN

How It Works

1. You create rules like: "For Stone — Pickaxe with Efficiency 5 + Haste"
2. When you start breaking a block, the mod checks:
   • Do you have the Haste effect?
   • Is the Efficiency level high enough for instant mining?
   • Which tool in your inventory is the best match?
3. The mod automatically switches your hotbar slot to the optimal tool
4. If tool return is enabled — it switches back to the previous tool after mining

Example: Haste + Efficiency 5

Stone (hardness 1.5) requires a mining speed ≥ 45 for instant mining.

Situation	Pickaxe	Speed	Instant?
No Haste	Eff 5 Diamond	~45	Barely
Haste II	Eff 5 Diamond	~63	Yes
No Haste	Eff 10 Diamond	~126	Yes

The mod will choose Eff 5 if you have Haste (saving durability!), and Eff 10 if you don't have Haste.
