Used to craft items on the **SMASH** workbench.

Hammers have a **Base Break Chance**, **Current Break Chance** and **Crafting Bonus**. It seems like every hammer starts with a Current Break Chance of 0% then begins to increase with each use risking it **shattering** during a crafting operation.

The formula for the break chance increase may be something like:\

**Current Break Chance** += **Base Break Chance** + **Recipe Break Chance**

Maybe there’s even some randomness thrown in too?

12/27/25: It looks like **Current Break Chance** resets to 0% at Universal Basic Cheese daily reset, but after using the hammer it continues to accrue wear at the pre-reset **Break Chance**.

| Hammer | Base Break Chance | Crafting Bonus |

| <!bronze_hammer> | 5% | +5% |

| <!mithril_hammer> | 10% | +20% |

| <!adamantine_hammer> | 2% | +35% |

| <!diamond_hammer> | 1% | +90% |
