Controlled Fracture

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

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:

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