Locks Reforged

[1.7.3]

A major lock-picking rebalance replacing random pick breakage with a predictable durability system.

Lock Picks Now Use Durability

Lock picks no longer randomly disappear after a bad guess.

Instead, every wrong pin damages the pick, and it only breaks when its durability reaches zero.

Default durability:

• Wood — 32
• Gold — 40
• Copper — 48
• Iron — 96
• Steel — 192
• Diamond — 384
• Netherite — 768

The durability bar now shows exactly how worn the pick is.

Stronger Locks Damage Picks More

Each lock tier now has its own Pick Wear value:

• Wood — 1
• Iron — 3
• Steel — 6
• Diamond — 12
• Netherite — 24

This means stronger locks wear picks down much faster.

A pick used against a lock of roughly the same tier is generally balanced around 32 wrong pins before breaking.

Near-miss guesses cost less durability than completely wrong guesses.

Pick Strength Has Been Simplified

Lockpick Strength no longer affects durability.

It now only determines whether a pick is strong enough to attempt a lock through the existing Complexity system.

Pick durability is configured separately.

Enchantments Updated

Lock-picking enchantments have been adjusted for the new system.

• Sturdy — increases durability damage caused by wrong guesses.
• Finesse — reduces durability damage by 15% per level by default.
• Last Catch — has a chance to completely prevent durability loss from a wrong guess.
• Shocking — now triggers on actual pick breakage much less often.

Enable:

Shocking Triggers On Wrong Pin

if you prefer Shocking to activate more frequently.

A wrong guess always costs at least 1 durability unless Last Catch activates.

Mending & Unbreaking Support

Lock picks now behave like normal Minecraft tools.

• Mending works on all pick tiers.
• Unbreaking reduces durability loss normally.
• Netherite picks can still be repaired with their material at an anvil.

Pack authors can also define a pick with:

"durability": 0

to make it permanently unbreakable.

Lock Picks No Longer Stack

Damageable lock picks now have a maximum stack size of 1.

As a result:

• Copper, gold, iron, steel, and diamond pick recipes now craft 1 pick instead of 2.
• Villager and Wandering Trader trades now give 1 pick instead of 2 for the same price.
• Loot tables are unchanged, but multiple generated picks appear as separate items.

Existing stacks from older saves remain safe, but will reduce to one as Minecraft moves them through inventories.

Unbreakable picks with durability = 0 can still stack.

Configuration

Added new customization options.

Lock Stats

Each lock can now define:

pick_wear

This can be configured through:

• [Lock Stats] in locks-common.toml
• Lock JSON definitions
• Datapack lock-stat overrides

Lock Pick Definitions

Lock pick JSON files now support:

durability

Pick durability must be configured in:

config/locks/lockpick_types/<name>.json

because durability is determined when the item is registered.

Enchantments

Added:

• Sturdy Wear Per Level
• Finesse Wear Reduction Per Level
• Near Miss Wear Multiplier

The old Finesse Strength Per Level option is no longer used.

Third-Party Lock Picks

Items added to the locks:lock_picks tag that do not support durability are treated as unbreakable instead of being consumed.

Multiplayer

The network protocol remains at 3.

1.7.2 and 1.7.3 are technically protocol-compatible, but clients and servers should still be updated together because lock-picking behavior has changed.

Reliability

• Durability calculations now correctly respect Unbreaking and Creative Mode.
• Removed unnecessary NBT writes when reading pick strength, improving stacking behavior for compatible items.
• Added additional automated tests for lock-pick durability and wear calculations.
