Treachery is the rune word 'ShaelThulLem' for body armor in Diablo II: Lord of Destruction.

Although Treachery is intended for the Assassin class, any class can benefit from the chance to cast Fade or the massive Increased Attack Speed, making this a nice armor to keep in the stash when lacking resists or damage reduction.

It is commonly used for the pre-buff effect: putting it on and standing in a fire until Fade procs for the resist boost (60% resist all) for almost 5 minutes (288 seconds), then swapping back to preferred armor.

Despite its inexpensive cost, when made in an ethereal elite armor, this Rune Word is one of the best hireling armors in the game since the increased attack speed greatly increases the hireling's damage output.
