Mountain - abunchofhacks/epicinium-documentation GitHub Wiki
The Mountain tile is inaccessible by ground units. There are 5 indestructible mountains on the tile that can be part of an indiscriminate damage step.
When generating the map, spaces in close proximity to a Mountain tile have increased Humidity.
Unlike the Water tile, the Mountain tile does not help nearby City, Town, Farm and Outpost tiles grow.
Ridge
The Ridge tile is a variant of the Mountain tile. It has 4 mountains on it instead of 5, and it does not increase the Humidity of nearby spaces.
