This weapon consists of a small metal tube hidden within a sleeve; the tube holds a short, spring-loaded bamboo shaft.

Benefit: The wielder gains a +2 bonus on Sleight of Hand skill checks made to conceal an arrow tube shooter on his body. Releasing the fastener allows the spring to force the arrow out. Once a shaft is fired, the tube must be reloaded before it can be used again. Reloading a tube is a full-round action, or a standard action if the wielder has the Rapid Reload feat.
