Enigma is the rune word 'JahIthBer' for body armor in Diablo II: Lord of Destruction. One of the most popular body armor runewords; Enigma grants, among other things, +1 to Teleport no matter the class (not charges, but the actual Oskill). It provides other useful stats, but Teleport is the most valued bonus, which is very useful to many builds. Many other PvP classes also benefit greatly from Teleport. On the minus side, Enigma is a very expensive rune word to build.
