Killerwatt

Killerwatts are Slayer monsters that require level 37 Slayer to kill. Players must wear insulated boots to fight them, otherwise they will get damaged by the thunderclouds inside the area. Note that as soon as you select it as an attack target, it will run towards you and attack you as if it was aggressive, sometimes attacking you first.

Location
Killerwatts can be found through a portal on the top floor of Draynor Manor, by Professor Oddenstein.

The Killerwatt plane is filled with flashing lights, so it is advised that anyone with eye problems or is epileptic either not go there or plays in low detail.

Strengths and weaknesses
Killerwatts use both ranged and melee, and can hit very rapidly. On distance they will always attack with ranged so if you can, use the Protect from missiles prayer and pack several vials of Prayer Potions. The ranged attack also seems to be magic-based (though it is blocked with protect from range), so wearing dragonhide armour can help resist some of the attacks. They are also considered by some players to be very difficult for their level.
