In wikia:
"You cannot craft items of a higher quality rating using smithing recipes higher than your skill value (sqrt(Strength*Smithing))."
I have STR 133 and smithing 25 and bronze of quality 42. I tried to craft some metal stuff, like hard metal cutlery and it for some reason have quality 29... Okay, i have skill less than quality of material so let it be (42+25)\2=33.5 but NOT a 29. Please explain me how this all s..tuff is calculated. Thanks.
