Warning: Users with photosensitive epilepsy should not attempt to go in the portal where these monsters reside, due to the flashing lights and strobes inside. Professor Oddenstein will mention this warning prior to entering the killerwatt plane.
Killerwatts are Slayer monsters located through a portal on the top floor of Draynor Manor that require level 37 Slayer to kill as well as completing Ernest the Chicken. 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 1-14 Hitpoints by the thunderclouds inside the area.
Note: 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, although Prayer flicking is still possible despite their attack speed. Using Ranged or Magic from across clouds will limit them to their Ranged attack, allowing players with prayer to safely complete this Slayer task. As usual, using the Protect from Melee prayer will prevent all Melee damage if a player has brought high Ranged Defence gear. 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 its Ranged attacks until it reverts to its base form.
Since killerwatts are a bit hard to kill, players often skip this task due to the killerwatt's attack since their attack is much dangerous.
