Know which Emperor item you're looking for

The Emperor Modulator is one of those ARC Raiders Items you need to identify before committing to a long loot run. It's required for Gunsmith IV, and the route described here takes you inside the fallen Emperor on Pendola Pass. Don't confuse it with the Emperor Gateway Conduit. That opens the entrance. Amplification Modules are separate rewards, too. The important catch is that there's no established numerical drop rate for the Modulator. Those location tables showing 0% don't mean it never appears; they contain no useful player voting data. You're looking at an uncertain reward, not a task you can finish after a guaranteed number of attempts. Plan around that before spending your entry materials.

The preparation starts at a relay

During Redirection, look for an active Damaged Emperor Relay. Relays begin activating at around 25 minutes remaining, so you've got time to gather supplies before moving toward one. Watch for the red beam and the countdown on its map icon. Search the relay, collect an Emperor Beacon, then deploy it somewhere open. Get under cover afterward. The falling debris damages health and shields, and the beam advertises your position to everyone nearby. Once the payload lands, search the large upright section for ARC Conductive, Insulated, and Plated Couplers, plus a possible Emperor Gateway Conduit Blueprint. The smaller wreckage supplies ARC parts instead. Don't spend the whole remaining raid searching the wrong pieces while another squad approaches.

Bring the ingredients home before opening anything

You'll need one of each coupler and the learned blueprint to craft an Emperor Gateway Conduit at Workbench I. You can't make it during the raid, and teammates can't pool their couplers for that crafting step. Extract first. The Sizing Things Up quest offers another route to a Conductive Coupler through the Buried Harvester Payload near the Emperor entrance, but that's only one ingredient. With a crafted conduit ready, enter another Pendola Pass match and find the socket beside the round hatch at the Emperor's base. Using the conduit opens the interior. Climbing the exterior leg is a different trip entirely; reaching the top doesn't replace this entrance requirement or establish a way to collect the Modulator.

Inside, survival comes before searching

Bring equipment for both electrical obstacles and ARC enemies. The described setup uses an Anvil, a Hullcracker, a Snap Hook, healing supplies, shield chargers, and Stims. Shoot electrical nodes before crossing affected surfaces, then move while they're discharged. The rooms between the entrance and loot area can appear in different orders, so memorizing one run won't cover every layout. Gas drains stamina. Moving walls need patience. Long drops can end your attempt before you reach anything worth carrying. Look for the sealed doors with two white lights to continue; yellow-light doors lead back or outside. Search breachable round panels along the ascent when it's safe, but don't let a container distract you from a Hydra or an exposed crossing.

Leave yourself enough time to get out

In the last hangar, shoot three electrical nodes on each side, six altogether, to release the wall canisters. That also brings more ARC activity into the room, including a Vaporizer. Use cover and wait for it to leave before searching. Orange canisters are bombs, and anything flashing deserves some distance. Check the available loot before taking either exit, since leaving the structure doesn't complete extraction. Secure the Modulator in a Safe Pocket where possible, then call a Ballistic Gondola. The nearby Reckless Transceiver is convenient but exposed. If you choose to buy ARC Raiders Materials for preparation, keep that separate from your expectations about the interior rewards. Entry supplies aren't a promise that the Modulator will appear.
