Maximum slope

Main / Misc / Maximum slope

Buildings

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

Walls and fences

To calculate the maximum slope you can build a fence, stone wall, or tall stone wall on, based on your carpentry or masonry skill, use the following formula (submitted by ketza):

Max slope = (3 * √skill) + 10

(3 times the square root of your skill, then add 10)

Note: The answer 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: To start planning minimum of 5 skill required, even for totally flat tiles. *as of 12/22/12 (or some time before)

Skill	Maximum Slope		Skill	Maximum Slope		Skill	Maximum Slope
1	13		16	22		49	31
2	14		19	23		54	32
3	15		22	24		59	33
4	16		25	25		64	34
6	17		29	26		70	35
8	18		33	27		76	36
9	19		36	28		81	37
12	20		41	29		88	38
14	21		45	30		94	39

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 20 making it unable for animal driven carts to walk up. To find out if this hidden edge is steeper than 20 you need to use the Pythagoras Theorem by taking the two slope numbers and filling in the formulae. You can use this calculator.

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.

Mining

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