The helmet was constructed by a magical being of high potency. One of its powers seems to be that it can protect the wearer's body from all harm. For instance it has been written that one owner of the helmet was infected by parasitic Brain-eaters, a worm which burrows through its hosts flesh and bones on their way to the brain. Upon putting on the Helmet the Brain-eaters were driven from the wearer's body. As for other powers, these are not recorded, although many believe some power over water may be bestowed by the helmet.
