All the crafting guides say to drag metal/leather scraps over the armour and it boosts the armour rating. This does not work I have 4 crafting and 5 blacksmithing, I have a hammer, I drag drop and nothing...
If you have 4 craft and 5 blacksmith, you are at least level 7 - what do you want to do with cloth armour???? But if you think cloth armour = robes, it does not work with robes. And as youcan see here: http://www.larian.com/forums/ubbthreads.php?ubb=showflat&Number=526585 metal scraps on any armour need crafting 5.
