Resistance by damage type
At 100% resistance that method does nothing, no matter how long you keep at it.
| Grade | Explosive | Fire | Bullet | Slash | Blunt | Stab | Arrow |
|---|---|---|---|---|---|---|---|
| Twig | 0% | 50% | 80% | 80% | 80% | 80% | 80% |
| Wood | 10% | 90% | 97% | 80% | 98% | 90% | Immune |
| Stone | 50% | Immune | 99% | 98% | 98% | 95% | Immune |
| Sheet metal | 50% | Immune | 100% | 99% | 99% | 98% | Immune |
| Armored | 50% | Immune | 100% | 99% | 99% | 98% | Immune |
What that means
- Arrows are 100% resisted from wood upward. A bow will never break a building.
- Fire is 100% resisted from stone upward. Incendiary rockets and molotovs only work on wood.
- Bullets are 100% resisted by sheet metal and armored. Shooting walls only works on wood and stone, and even there the 99% resist means hundreds of rounds.
- Tools like hatchets and pickaxes do slash and blunt damage — fine on a wood wall, 98% resisted from stone up.
For walls, floors and stairs. Doors and boxes have their own health and are not here.
Satchels, beancans and explosive ammo are left out — the published numbers disagree.
