In Diablo II, the Jah-Ith-Ber rune sequence creates the Enigma runeword.
Enigma is made by inserting Jah, Ith, and Ber into a three-socket body armor in that order. Runewords require the correct item type, number of sockets, and rune order; placing the same runes in the wrong sequence does not create the intended item. Enigma became especially famous because it grants the Teleport skill to characters that normally cannot use it.
That mobility dramatically changed high-level character builds and multiplayer play. It allowed classes such as Paladins, Barbarians, and Necromancers to move quickly across the map without relying on a Sorceress. Enigma also provides strength, life, and enhanced defense-related benefits, making it valuable beyond its teleportation effect.
Players sometimes confuse Enigma with other popular armor runewords, including Chains of Honor. The distinguishing clue is the Jah-Ith-Ber sequence and the cross-class Teleport ability. The runeword is associated with Diablo II’s item-combination system rather than with a separate quest reward.
