If Totenreich has started to feel a bit too routine, the Agarthan Device is a smart way to shake things up without turning every match into a punishment. Unlike the harsher relics that crank enemy damage or mess with your build, this one changes the zombie type each round, so the pace stays fresh and you've still got room to play your own way. That's a big part of why people chase it, and if you're already looking for ways to buy BO7 Bot Lobbies or speed up the grind elsewhere, this relic has a similar appeal: less boredom, more variety. The best part is how early you can unlock it on Cursed Mode Tier 2. Round 15 is miles better than dragging yourself all the way to Round 60, especially if you just want a more interesting run and not a full-night commitment.



Finding the first two items
Your first job is collecting three key items, and two of them come from the same annoying little gamble. Head to Tyr's Head and start using the exit tubes. Sometimes they'll throw you into a Liberty Falls hotel room, where Mr. Peeks is tucked under the bed. Other times, you'll land in the room with dead Requiem soldiers. That's where the Soldier Helmet is sitting in a box on the lower shelf near the Point Turret. It's not hard, but it can be slow. You only get two teleport chances per round, so don't force it. A lot of players waste time getting tilted here when really it's just a patience check. Keep moving, keep a crawler if needed, and grab both items as the map finally gives you the rooms you need.



Getting the Walkie-Talkie
The third item takes more work. In the Core Foundry warehouse, use an ARC-XD to blow open the vent so you can reach the Group 935 Genetic Lab near Fishery Island. From there, you're dealing with one of those classic Zombies puzzles that looks messy until it clicks. Check the radiation-marked numbers, convert them into letters, then collect the correct jarred heads. Those heads are used to make a Necrospike, and that tool lets you open the locked cell with the Walkie-Talkie sitting under a bench. It sounds like a lot on paper, and yeah, the first attempt can feel clunky. After one or two runs though, the route starts to make sense, and it stops feeling like random lab nonsense.



Starting the side quest
Once the items are sorted, make sure one player is running Richtofen and has Melee Macchiato ready. Go to the Mystery Box area in the Core Foundry and punch the barrel to get his medal. After that, follow the side easter egg steps until Von List shows up. Place Mr. Peeks on the throne and the trial will open at the Dry Dock. This is the part where people get caught off guard, because zombies only take damage while they're indoors. If you try to fight too wide or too far out in the open, you'll just waste time and ammo. A Tier 4 Jotunn Star helps a ton, and Toxic Growth makes the whole thing way more manageable. It's not a fancy setup, but it works.



Best way to survive the trial
The easiest play is to move straight to the second floor of the Lighthouse and hold that choke point. Enemies funnel in cleanly, Toxic Growth slows the rush, and melee attacks become much safer than they look at first glance. That matters most on Waves 3 and 6 when the HVTs show up and the pressure jumps fast. If your timing is decent, you can keep the fight under control instead of getting dragged into chaos outside.
