Staff weapon

From The Stargate Omnipedia

Staffweapon.jpg

A weapon of Goa'uld design. Several feet in length, its head divides into four parts when activated, releasing powerful bolts of plasma energy. The weapon is powered by a small, green container of liquid naquadah. It is generally considered to be a weapon of terror, since its ability to accurately target a moving object, let alone a motionless one, is less reliable than some human weapons that have pin-point accuracy.

The staff weapon is, before the zat'ni'katel, the weapon of choice for Jaffa, who train to be proficient with both aiming and firing the weapon, and with using it in hand-to-hand combat. Young warriors are taught personal combat techniques with a wooden training staff, shaped to resemble a staff weapon.
