what depends on how good i can repair armor/weapon?
Arms lore and BS or just arms lore?
anyone knows where can i see information with weapon/armor at what skill i can repair?
and does it takes lot of ingots to repair at all?

i dont think it takes ingots and u need bs mostly for repairs but as far as i know arms lore will come most handy too....

u dont need a set skill level to reapir certain things, but a higher bs lvl and armslore will allow u to repair with less chance of failing.
