Bundle tank

Prior to an update, holding a bundle would cause computer controlled monsters to focus aggro on the holder due to the implementation of the AI. 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 enemy attack or interrupts. Almost any Bundle or carried item caused this behavior. The most frequent bundle tankings involved the Unholy Text dropped by the Priest of Menzies in the Fissure of Woe and cogs in Sorrow's Furnace.

It is theorized that this was changed to keep from putting inappropriate stress on Ritualists, who have item spells that would focus aggro.
