In Diablo II, the Enigma runeword is made by inserting Jah, Ith, and Ber runes into a three-socket body armor.
Runewords are item recipes that activate when specified runes are placed in the correct order inside a socketed item. Enigma became famous because it grants the Teleport skill to characters that normally cannot use it, dramatically changing movement and class-building strategies.
The recipe requires the runes Jah, Ith, and Ber, in that order, and the base armor must have exactly three sockets. A common mistake is to confuse Enigma with other high-level runewords such as Infinity, which uses Ber, Mal, Ber, and Ist in a four-socket polearm. The base item and socket count matter as much as the rune sequence.
Enigma’s power made it one of Diablo II’s most recognizable endgame items. Its expensive runes and mobility bonus also influenced trading, player-versus-player builds, and the way many classes approached late-game farming.
