Killerwatts are Slayer monsters located through a portal on the top floor of Draynor Manor that require level 37 Slayer to kill. Players are suggested to wear insulated boots to enter the Killerwatt plane and to fight them; if you are not wearing insulated boots before you enter the portal, Professor Oddenstein will warn the player; giving them the option of whether or not to go in. If you put them on after you are inside, you will get hit for up to 14 hitpoints by the thunderclouds inside the area.
Warning: Killerwatts are much more dangerous than what their combat level may suggest; both their ranged and melee attacks will hit players every 1.2 seconds, much faster than the speed of an abyssal whip or scimitars, and their melee attacks are exceptionally accurate. Many players skip this task by taking another task in Burthope to avoid wasting time and food on Killerwatts. As usual, using the protect from melee prayer will prevent all melee damage. The protect from missiles prayer will prevent all ranged damage. Their ranged attack is magic based, and thus high magic defence armour such as dragonhide will provide the best defence against the ranged attack.
There is a way to prevent the killerwatts from using their ranged attack; effectively greatly reducing their damage rate, and allowing you to fight them in metal armours. They will not attack you with ranged attacks unless you strike first. Therefore, when using a melee weapon, you can click the killerwatt from a distance, and then click the ground to stop moving towards the killerwatt. Turning run off will make it much easier to stop yourself before you strike the killerwatt. This will make the killerwatt aggressive to you, and it will approach and attack you in melee, striking you first. With auto-retaliate on, you can retaliate without triggering their ranged attack. If you accidentally strike a killerwatt first, you can use protect from missiles and/or retreat through the portal. After returning through the portal, the killerwatt will no longer be aggressive towards you, but you also can not attack it without triggering it's ranged attacks until it reverts to its base form.
