New skill: Assay mining: requires mining
Enables the player to find new iron ore mines, sort of like dowsing, but insteadof a dowsing rod the tool might be the regular pick, or a tool might not be needed. New mine site spots to be invisible to anyone without the assay mining skill. As well as iron mine sites the skill would enable the character to located deposits of other minerals.
Assay miner could locate either deposits of ores or locations where a mine could be opened: copper, tin, lead, silver, zinc which can be mined for ore and in addition to that gems and sulphur.
Copper and tin in the crucible makes bronze. Copper and zinc in the crucible make brass. Tin and lead make pewter. They all take a lot less time than the steel does.
Gemcutting skill enables the player to cut gems out of the raw form of gems, uncut gems. A percentage chance randomly determines if the gem is garnet (common), diamond, emerald or ruby.
Silver maybe used to craft jewelry items, with or without the addition of a cut gemstone. These can be worn like the bear claw necklace and might carry a minor charisma bonus.
Sulpher can be used as a fertilizer to increase the seed yield of fields, in the making of matches and possibly in the making of explosives.
Fields that are fertilized with intestines, cow eggs (or a related by product of cows), sulphur, plant fibre or straw have an increased chance of producing more seeds.
To make saltpeter cow eggs or the related by-product of cows must be collected and stored. Ten units stored for a certen length of time turn into 9 units of fertilizer and one unit of saltpeter.
To make explosives sulpher must be combined with saltpeter and charcoal to make gunpowder and then put in a keg or barrel. There should be a risk of explosion with hp damage whenever explosives are manufactured. Since this is primitive explosives the result is not hugely strong but several gunpowder bombs can begin to damage a pallisade or wall. More importantly a bomb set of in a mine shatters a section of the wall into ore.
