Alows the enchantment of weapons, magestaffs, necklaces, rings, helmets (not hoods) and torso armor (Cloth and up, but not any other clothing). Some enchantments can only be made on certain kind of objects.
Go to the Enchanting ring in major cities, put in 5 of each ingredient needed for a recipy and a Catalyst (Nith, Ichor, Numen), after marking the correct object in the list or dropping it in the box. Click Enchant, and if you have the correct recipy, and 100 Gold in your bag for the use of the ring, it will become enchanted. (Remember to put ingredients for Transmute recipies in the right row when enchanting weapons and staffs.)
