In Dragon’s Dogma for the PS3 and Xbox 360, some of the items you come across in the game may lead you to believe that you can craft armor with them, but this is somewhat misleading.
You can’t craft armor from scratch in the game, but you can enhance your pieces of armor however.
If you visit an armor merchant in the game, you’ll see an option for armor enhancement.
There are three levels of enhancement. The first only requires gold, the second requires fairly common items and gold, and the third requires uncommon or rare items and gold.
Each level of enhancement will increase the stats of the armor, and lower the weight.
