It can use make snakes run away when they closed the area which that Keris Naga Runting stab in it ground... It can use too for killing supernatural beings and spell for love attraction (but I never use it the last ones, because I am never interest with love because cast). The spirit guardian of Naga Runting was a black Snake with red eyes and don\'t have tail.. So they look like only a half body without tail ( I have met the Guardian once, when he intoroduce his self to me as his new master)
