Bastet

Bast is Mariah's  stand, it has a simplistic form resembling an outlet that can be placed anywhere. This sparks the curiosity of a person and upon touching the outlet Bast's ability activates causing the person to become irradiated with a strong magnetic force that attracts nearby metallic objects towards the victim, more than one person can be placed under the same 'magnetic curse'. Slowly the objects will either overwhelm the person or simply impale them.
