Meantime, I am implementing skills for the role-playing system. There are 26 skills in total. It was decided to divide the weapon into only 4 skills, since personally I was always embarrassed that a warrior who can handle an ax well, for example, picking up a sword or mace completely loses his skill.
The skills themselves, in addition to their numerical value, also have a skill rank: normal - strong - legendary - godlike. The skill itself can be raised at any time if the character has free skill points. But to raise the power of the skill, you need to look for the appropriate teachers. Increasing skill power often provides significant benefits. For example, possession of fast weapons (daggers, whips, cathars) at the legendary level allows you to use a dagger in your left hand.
Not every character can achieve the high power of every skill, it depends on the character class. For example, any magical class (Sorcerer, Sorcerer, etc.) can master Veles' cuneiform at the middle level, but to master it at the legendary / divine level, only the Magus / Wizard class (promoted from the Warlock / Witch) can.
