Strengthening

Strengthening uses

A first cast grants five Strengthening uses. Recasting adds another five up to STRENGTHENING_CAP. The item tooltip shows Strengthened while uses remain.

While uses remain, the item has Minecraft's Unbreakable property. A Strengthening use absorbs durability loss.

A strengthened melee weapon spends a use for its damage bonus. Each worn armor piece spends one when its wearer is hit. Other items spend one when used to break a block.

When the last use is spent, Strengthening is removed. An item that was already Unbreakable before the first cast retains that property afterward; other items return to their ordinary durability behavior.

Combat effects

A melee attack with a strengthened item in the main hand adds 4 damage. An attack can spend two uses: one for the damage bonus and one for the weapon's normal durability loss. The bonus does not apply to arrows.

A strengthened armor piece can spend two uses when its wearer is hit: one for the hit and one for normal durability loss.

Mining effects

An item in the main hand receives +3 block breaking speed while strengthened. Tools also harvest as though they were one material tier stronger: wood advances to stone, stone to copper, copper to iron, iron to diamond, and diamond or netherite stays at netherite capability.

Any strengthened item can harvest blocks that a wooden pickaxe could harvest. Doing so with an item that is not a tool spends one Strengthening use.

Blacklist

STRENGTHENING_ITEM_BLACKLIST defines items excluded from Strengthening. The list accepts item registry IDs. A STRENGTHENING_CAP of 0 disables Strengthening entirely. Rejected attempts do not consume mana or the scroll.

Progression uses

Strengthening is also a preparation state used by several special acquisition paths, including Clarent, Emrys, Replica, Nobu, and William and R'lyeh. Follow each item's page for its additional material, location, or action requirements. Creating a Projection copy removes Strengthening from that copy.
