The Circles of Slaughter are a great way to farm adventure, money, and weapons in Borderlands 3. There are three in total, spread throughout the game, and you’ll have to track them down before you can take part.
The Circle of Slaughter happens over five waves, and survive and your task will be to kill all enemies. Each wave, the enemies get a little harder, and the possible rewards get much better.
The Cistern of Slaughter
The Cistern of Slaughter can be found on Promethea, on the Meridian Metroplex. You will have to go to the middle of the map, then fall down into the very bottom. You will notice a underground ramp leading downwards. Follow it and keep to the right, and you will arrive at the load point for the Cistern of Slaughter.
The Slaughter Shaft
For the Slaughter Shaft, you need to get to the Hold of Konrad on Pandora. This won’t be accessible until near the end of the effort. You can observe the loading point for the Slaughter Shaft shown on the map below.
Slaugterstar 3000
Make your way to Desolation’s Edge on Nekrotafeyo, and you’ll find a pursuit giving near the place shown on the map below. It won’t pop up until you are close to the area. This exploration will send you back to Sanctuary, and Slaugtherstar 3000 will now be a destination you’ll be able to head to using a drop pod.
