About this project

What does Controlled Fracture add?

Controlled Fracture (Forge 1.20.1)

A precision vein-mining system focused on control, durability management, and progression.
This is not a generic vein miner: it is opt-in, tool-restricted, and enchantment-driven.

Core Rules

Must be sneaking to activate
Pickaxes only (other tools never activate)
Unenchanted pickaxes behave like vanilla
Hard caps prevent lag
The tool is never allowed to break (mining stops before it would)

Enchantments

Andesite Breaker I–III ("controlledfracture:vein")
Break connected andesite while sneaking.

Levels: I, II, III
Only works on andesite
Search radius and hard cap are limited for performance
Higher levels increase block cap and efficiency

Durability behavior:

Mining stops early if the tool would become unsafe
Shows an on-screen warning when durability is too low

Obsidian Shatterer ("controlledfracture:obsidian_cutter")
Controlled multi-block obsidian mining.

Level: I
Only works on diamond and netherite pickaxes
Sneak to activate
Hard cap prevents lag
Can coexist with Andesite Breaker (Breaker tier increases the obsidian cap, but an absolute hard limit always applies)

Loot and Progression

Andesite Breaker I
Chest loot:

Dungeon spawner chests
Mineshaft chests
Ruined portal chests
Trades:
Librarian (mid tier)
Wandering trader (extremely rare and overpriced)

Andesite Breaker II
Chest loot:

Bastion chests
Ancient City chests
Stronghold corridor + crossing chests
Trades:
High level librarian only (expensive, low chance)

Andesite Breaker III
Chest loot:

Ancient City (rare)
Bastion treasure (rare)
End City (rare)
Trades:
None

Obsidian Shatterer
Chest loot:

Stronghold library (main source)
End City (secondary source)
Trades:
None

Anvil Rules
Book merging:

Breaker I + Breaker I → Breaker II
Breaker II + Breaker II → Breaker III

XP costs:

Book I → II: 10 levels
Book II → III: 20 levels
Tool I + Book I → II tool: 12 levels
Tool II + Book II → III tool: 24 levels

Hard restrictions:

Only pickaxes can receive these enchantments
Obsidian Shatterer only applies to diamond/netherite pickaxes

Compatibility

Minecraft: 1.20.1
Loader: Forge 47.x
No other mods required

Notes
Creative mode can bypass normal restrictions. Survival behavior is enforced through the enchanting/anvil systems and loot progression.
