Cannot be tamed.
Located in Mechagon. Gemicide appears in a cave directly west of The Outflow. This cave is normally open and empty, but on days when Drill Rig Construction Projects appear then occasionally the cave will be sealed and a drill rig appears outside. If you activate and defend the drill rig then the cave will open and Gemicide will spawn. Gemicide has azerite crystals on its head and is currently classed as an Elemental.
