40d:Stone

Stone or rock is a naturally occuring solid aggregate of minerals. It sometimes leaves behind boulders after being mined (the drop rate is dependant on the skill of the miner). Other types of minable tiles include soil and sand.

Stone is divided into three key categories:

• Metal ore: stone that produces metal bars when smelted
• Economic stone: coal and stone that is used as a flux, or has other desirable features
• Other stone: stone that is only used for items and structures and has no special features other than color, value, and weight

Other Stone found in layers

All other stones have value 1, except obsidian, which has a value of 3.
