Restrictions to be imposed for prospecting skills, Mody?
In fact there are two limitations. The first is as described above you can only search for a basis for ore. This means that, like silver, gold, precious metals such as real silver ore (any kind of “green” grade ore) are not be used for mineral exploration. The skills can not be used in a special metal ores on, such as black iron ore, sub-quarry, and so the blood. Second, your jewelry processing skills must meet the general mining professionals the ability to mine such ore grades (for example, need 175 points, dense silver ore, iron ore, need 300 points, magic, Caine steel ore required 350 points).
