Killerwatt

Killerwatts are monsters that require Lv 37 Slayer ( yes, members only ) to kill. In addition, you need to be wearing Insulated boots, bought from any Slayer Master. They look like a shiny silver star. The space that houses Killerwatts is known as Killerwatt Plateau, or some choose to call Torn Space Rift. Must Complete Ernest the Chicken to get there, though.
