# Maximum slope

## Buildings

Wall plans for houses can only be built in flat land (0 slope), regardless of skill.

## Walls and fences

To calculate the **maximum slope** you can build on, based on your carpentry or masonry skill, use the following formula submitted by Ketza:

*Max slope = (3 ** √*skill) + 10*

Skill | Max Slope |
---|---|

6 | 17 |

8 | 18 |

9 | 19 |

12 | 20 |

14 | 21 |

16 | 22 |

19 | 23 |

22 | 24 |

25 | 25 |

29 | 26 |

33 | 27 |

36 | 28 |

41 | 29 |

45 | 30 |

49 | 31 |

54 | 32 |

59 | 33 |

64 | 34 |

70 | 35 |

75 | 36 |

81 | 37 |

88 | 38 |

94 | 39 |

**Note:** Maximum slope is rounded *down*

Alternatively, to find the skill required for a given slope, use this formula:

*Skill = (slope - 10)^2 / 9*

This answer gets rounded *up* instead.

**Note:** These skill limits do not apply when building small stone walls at cave entrances.

Two corners going into 1 corner can result in a "hidden edge" being steeper than 40 making it unable for animal driven carts to walk up.

## Farming

The sum of the north-south and east-west slope must not exceed 8 dirts.

For example if a tile has a slope of 6 dirts from north to south, the maximum slope from east to west is 2 dirts.

Another example, the north to south and east to west slopes may be 4 dirts steep each.

## Tunneling

When tunneling to create a new mine entrance, the maximum slope of the rock tile you are tunneling into is 270.

## Digging

The maximum slope you can dig on is 3 x [your digging skill]. E.g. A skill of 50.25 in digging means you can dig on, or adjacent to, a slope of up to 151 dirt.

## Surface Mining

On PVE servers, the maximum slope you can mine on the surface is 3 x [your mining skill]. E.g. A skill of 50.25 in mining means you can surface-mine on, or adjacent to, a slope of up to 151 dirt.

On PvP servers, the maximum slope you can mine on the surface is 1 x [your mining skill].
