If you've been assigned Killerwatts as your Slayer task, you're in for a zappy and unique experience. They are a great mid-level Slayer task. They're fast to kill, provide consistent XP, and have a predictable attack pattern that makes them ideal for safespotting or prayer flicking. Killerwatts are electric-themed monsters that offer solid Slayer XP and can be safely farmed with the right setup. In this guide, we'll cover everything you need to know--from requirements to gear, locations, and safespots.

To be assigned Killerwatts, you'll need:
Level 37 Slayer
Recommended:
Killerwatts are only found in one location:
Access this area via the portal on the top floor of Draynor Manor.

Once you complete "Ernest the Chicken," the portal becomes accessible. Entering the portal takes you to the killerwatt zone.


This is just an example gear set up, if you have better gear please don't be shy about using it, this is to give you a rough idea of what you need to carry and keep in mind that there will always be better options in terms of armor and weapons.
Ranged Setup

Melee Setup

Inventory

If using melee without prayers, consider wearing gear that provides high Magic defense.
Killerwatts can be safespotted using the holes in the Killerwatt Plane. These holes act as barriers that the monsters cannot cross, allowing you to attack from range or with spells while avoiding melee attacks.
However, note: they can still hit you with their magic-based ranged attacks, so safespotting doesn't make you completely immune unless you're using Protect from Missiles.

It is not possible to use a Dwarf Multicannon in the Killerwatt Plane.
Due to the isolated and instanced nature of this area, cannon placement is disabled entirely. All combat must be done manually using your chosen combat style.
