Anti-gravity belt

From Halopedia, the Halo wiki

Template:Ratings The Antigrav Belt is a device worn by lesser Prophets of the Covenant. Less advanced and less ornate than the High Prophets' Gravity Thrones, Antigrav Belts are worn around the waist of the Prophet. They serve to keep the Prophet levitating for two reasons; One, so that they do not need to walk and two so that they can look down upon their lesser commanders, even the Elites. This is another way they display their power in the Covenant.

These belts do not have very much power of raising its ocupant vertically. When Prophets need to travel up great distances, such as ascending up the Dreadnought in High Charity, they must link arms and use the combined power of many antigravity belts to boost themselves up.
