Bandos' head diviner, Davosi, was in charge of the weapon's construction; Davosi stated that the weapon would "help Bandos become ruler of the gods". The Scarecrow was powered by divine energy, which Bandos and Davosi collected by sending out caravans to sites throughout Asgarnia and Misthalin. At the sites, the caravans utilised the skill of Divination to siphon energy wisps, creatures created from the Anima Mundi that were created as a result of Guthix's death.
