Prior to April 25, 2006, holding a bundle would cause computer controlled creatures to focus aggro on the holder due to how the AI worked. This allowed healers to focus healing on the so-called bundle tank while allowing the rest of the party to attack freely without fear of retribution. Almost any bundle or carried item caused this behavior. The most common bundle tanks used Master gears in Sorrow's Furnace and the Unholy Text in the Fissure of Woe.
