MWZ Dark Aether Rifts Boost

To access the Dark Aether Rifts, complete Act 4's 'Bad Signal' Story Mission. Upon entering the portal, break 4 seals and defeat the main boss, Gorm'gant. You'll receive the Locked Diary as loot, one of the 4 items required for permanent access to the portal at any time.

After that, you'll need to acquire a security camera by killing a harvester orb with the Dead Wire mode equipped on your gun. It will turn gold, and after you kill it, you will get a purple surveillance camera. Following this, you need to find an orange ether tear and fly through it while having that purple security camera in your inventory. After completing those steps, a purple bounty contract will spawn. Eliminate a special Elite enemy to collect the golden Surveillance Camera as loot.

To acquire the next artifact, equip the Brain Rot mode. While progressing through the ether nest, shoot the cyst once to turn it green. Collect the purple pill bottle, then locate another ether tear and glide through the green rift. This action will spawn another purple bounty contract. Eliminate another Elite enemy to obtain the golden version of the Pill Bottle as loot.

The Dog Collar is the final item required. Head to any dog house in the environment and deposit 1 piece of Flesh and 1 Molotov. This action will spawn the enemy dog. Eliminate it to loot the purple Dog Collar. Locate the red ether tear in the air, which will also spawn a purple bounty contract. Fulfill the contract to collect the golden version of the Dog Collar as loot.

You can now proceed to place all 4 legendary artifacts onto their pedestals. Upon doing so, a massive Dark Ether rift will appear, housing a Mega Abomination that must be defeated. After its defeat, a reward rift will spawn containing 1 Sigil. Use the Sigil as a key to open the portal.
