Mineral

This article is a work in progress! Heck, it's the draft of a draft, as you can see.
Minerals are a type of resource that can be found in the overworld (the farm, backhills, and second homeland) but that are most abundant in the Mines. They can only be obtained by breaking the corresponding Node with a hammer of appropriate level. Each mineral node also has a chance of dropping a gemstone whose type is determined by the type of node.
Nodes come in small, medium and large sizes. It's more energy-efficient to break a large one, even if it takes several hits (always fully charge your tools, the PE used doesn't change but the damage does) than a small one. On average, a small node drops x ore and y stone, a medium one drops x and y, and a large one drops x and y.

** Mining comissions where this ore is a possible reward. Even if several commissions offer a particular ore as a reward, it doesn't mean the chances are the same. For more information on commissions, see the Commissions page. Once it exists.
