Go walking around a town, find a weaponsmith and he can upgrade your weapons.

My weapon has been broken every battle,i must repair it every time in town,can i fix it myself ?(like it was in Rus 13th century mod)

What weapon is it? Have you tried other weapons? Or same weapon of better quality?
Spears and lances break in battles, but you don't have to fix them.

i am talking about swards and axes,one or two battles and i must repair it,i think its too often,can i repair it myself,or somewhere else? can i turn off this option in some kind of menu?
