Enhanced armor items are some of the best armor sets in MU, but they can only be equipped by tier 4 character classes. Your character becomes a tier 4 character class after completing the 4th Class Upgrade quest. You'll want to start using these items as soon as you've become the 4th class. You can obtain excellent enhanced armor by hunting monsters, while ancient items are obtained from upgrading ancient Bloodangel items. NPC Priest James, in Elveland, sells Sealed Bloodangel armor items exchange for Ruud. The Sealed Bloodangel item can be upgraded several times to obtain enhanced items. Ruud is mostly obtained from mini-games, such as Maze of Dimensions, after becoming a tier 3 character class.
