About Studded LeatherEdit
The first defensive line for leather armor, being only slightly better than the common class cloth defensive lines, even their defenses and armor are extremely low, but they may at the beginning of your adventure give you a little resistance may in order to withstand the attacks of slightly more advanced monsters and even survive the one campaign in extreme mode.
And because they are of common class, they fall randomly, therefore it is not necessary to create this armor.
