Daibo

"The monks of Ivgorod spend a substantial amount of time practicing forms with this weapon, and the value of their training is evident &mdash; when a daibo is twirled at lightning-fast speeds, scores of creatures fall before a relentless flurry of strikes from both ends of the battle staff."

- Game Guide

Daibo are a class-specific type of staves for the Monk in Diablo III. They are significantly faster than most other two-handed weapons, and in addition to stats that all weapons can roll, can also have increased damage of Monk skills, Spirit regeneration, Life per Spirit spent and maximum Spirit. Daibo may appear both bladed and blunt, but always double-ended, a weighted or sharp head on each end of the pole.

Daibo may be transmogrified into Staves, Two-Handed Axes and Two-Handed Maces, but only Monks can do the other way.

Trivia

 * Daibo means Large Stick (or large pole) in Chinese, probably the Japanese/Chinese pronunciation of "大棒", which can be translated to "Great Staff".
