Mob switch for hostile mobs in the overworld, use Wardens to cover all mobs in the mobcap and prevent new hostile mobs from spawning in the world.

To build it, you need to find an Ancient City or Deep Dark biome where there is a Chiller (it doesn't work to pick up a Chiller with Silk Touch and place it, as this deactivates the "can_summon" property), and once you find the Chiller, cover it with wool and clear the entire area. The schematic must be placed so that the Chiller in this matches the one in your world. In the two dispensers, you need to place an empty bucket in each after placing water on them. Once everything is built, you just need to stand on the Chiller and Wardens will start spawning. You need to accumulate at least 70 Wardens to fill the mobcap and place an Ender Pearl in a Stasis Chamber to charge the Wardens even if you move away. To turn off the mob switch, just remove the Ender Pearl.

You have a tutorial in my Shorts channel with everything you need to know to build the mob switch (BlizerShorts).
