The fastest way to finish Greasing Her Palms is to stop treating it like a loot run. Celeste's three-map assignment is really a map-reading test: one locked room, one exposed landmark, and one upper-floor proximity check. Bring only what helps you reach the destination, keep the supplied key protected, and remember that ARC Raiders Items are far more useful when you extract with the quest progress already secured. The reward is a Lure Grenade Blueprint plus Speaker Components and Electrical Components, but the real payoff is learning routes you'll revisit.

Start With the Dam Key

Dam Battlegrounds should be your first stop because Water Treatment Control is the only objective with an item requirement. Celeste provides the Dam Surveillance Key after A Better Use, so place it in your safe pocket before deploying. Enter Water Treatment Control from the south, take the right-side interior corridor, then follow the next right turn toward the locked door near the security camera. Open it, cross fully into the room, and wait for the update. Don't just touch the doorway and sprint away; Arc Raiders location checks can feel slow when you're already thinking about the next fight.

What I'd Do Before Leaving Water Treatment Control

The room is worth checking if the building sounds quiet, but don't turn a completed quest stop into an extended sorting session. Water Treatment Control can pull players in because a key room feels like it must contain a jackpot. Sometimes it does. Sometimes the better call is taking the completion and leaving while nearby doors are still closed.

1. Put the Dam Surveillance Key in the safe pocket before deployment.
2. Confirm the quest update while standing inside the room.
3. Loot quickly only if the area has stayed calm.
4. Leave through the route with the fewest fresh signs of player traffic.

The Spaceport Objective Is Pure Positioning

At Spaceport, head southwest from Rocket Assembly toward the rocket sections facing Control Tower A6. You want the rear side of the southwestern thruster, not the most obvious spot beside the rocket. There is no panel to press and no item to collect. Stay behind the thruster for a few seconds until the objective registers. From what I've seen, players lose time here because they search every rocket component instead of recognizing that the trigger is simply a small patch of exposed ground.

Do This, Not That, Around Rocket Assembly

Approach through cover, pause before crossing the open final stretch, then leave immediately after confirmation. Don't stand there admiring the landmark or begin a long loot sweep with no cover nearby. The blueprint reward makes the quest worthwhile, and players planning crafting options can compare ARC Raiders buy BluePrints while keeping the actual run focused on survival rather than a greedy detour.

Buried City Rewards Patience

Space Travel in Buried City is where players most often overcomplicate the job. Reach floor six, turn right along the main hall, continue past the large wall sign, then take the second right toward the meeting-room area and its barricaded section. Stairs are usually the safer read when the building feels quiet; a rooftop entry can shorten the climb but may expose your movement. Check floor markings as you go. Guessing at the right hallway wastes more time than climbing one extra level.

A Better Completion Mindset

The quest has no fixed map order, yet the practical order is Dam Battlegrounds, Buried City, then Spaceport: remove the key dependency, handle the dense interior, and finish with the exposed thruster check using a light loadout. Each stop teaches a different Arc Raiders habit-protect mission items, identify proximity zones, and know when to extract instead of chasing one more container. That discipline matters more than min-max DPS here. Finish the check, verify it, then decide whether the current match is still worth risking.
