The bandos godsword is an unobtainable weapon that appears during the Misthalin Mystery quest. It is modeled after the Bandos godsword, but unlike the regular version of the item, the one during the quest only serves as an unobtainable decoration. It was added in case players were ever able to obtain the godsword using glitches.
During the quest, the sword is first seen in the kitchen with Mandy, where it is placed on a table. At the end of the quest, Mandy uses the sword to slay Abigale after she is revealed to be the Killer.
