Base.HammerStone

A stone hammer is a construction tool and weapon that can be made through foraging. It is strictly worse than a hammer as both a weapon and construction tool.

Usage

Construction

Main article: Carpentry

A stone hammer, in combination with wooden planks and nails, can be used as a replacement to a conventional hammer for most carpentry recipes. It can also be used for barricading doors and windows.

A stone hammer will lose durability during construction, whereas a regular hammer will not.

Weapon

A stone hammer can be used as a low tier weapon. Compared to a regular hammer, it is heavier, less damaging, has slightly shorter range, and has a much lower durability.

Breaking doors

The stone hammer is capable of breaking down doors dealing 2 damage per swing. For comparison, an axe deals 35 damage.

Condition

The stone hammer has a maximum condition of 5. Its rate of degradation is influenced by the short blunt and maintenance skills. The chance of losing durability can be simplified to the following formula: 1 in (5 + maintenanceMod × 2). Where "maintenanceMod" is calculated using the short blunt and maintenance skills.
Below is an example of the chance of losing durability at varying levels of the maintenance and short blunt skills.

For how this is calculated, see: Condition
Maintenance level Short blunt level Condition lower chance Average condition
0 0 1/5 (20%) 25
0 4 1/7 (14%) 35
0 8 1/9 (11%) 45
4 0 1/9 (11%) 45
8 0 1/13 (8%) 65
4 4 1/11 (9%) 55
4 8 1/13 (8%) 65
8 8 1/17 (6%) 85
10 10 1/19 (5%) 95

Repairing

A stone hammer cannot be repaired. However it can be crafted from raw materials.

Crafting

Stone hammers are made up of items which are scavenged via foraging.Tree branches, stones and ripped sheets (or twine) are required.
