Keys in ARC Raiders vary widely in value. Some open average loot spots, while others unlock locations that can completely change the outcome of a raid. The Stella Montis Archives Key clearly falls into the second category. If you manage to obtain this key, it’s definitely worth using — as long as you’re prepared to fight your way out with the rewards.


The locked door is found on the far northeastern side of the Cultural Archives in Stella Montis. It’s hard to miss once you know where to look. The entrance is a large supply bay door, and opening it creates a loud metallic noise that can easily attract nearby players.
Because the Cultural Archives is already considered a high-tier loot zone, expect heavy activity. Other raiders often patrol the area hoping to intercept players carrying keys or valuable loot. In addition to player threats, the Archives is also guarded by roaming Shredders. While these enemies can be dangerous, experienced players usually consider them less risky than running into a fully geared PvP squad.
Once the Stella Montis Archives Key unlocks the door, you’ll gain access to a room packed with valuable loot opportunities. Inside you can find:
Six high-value table drawers that have a chance to drop rare or even endgame blueprints
A blue valuables suitcase often filled with numerous collectible items
Multiple breachable crates containing crafting materials
A lootable computer terminal that can provide electronic components
Loose medical and mechanical supplies scattered around the room
Because of the number of containers packed into a relatively small space, this room can quickly fill your inventory with valuable gear.
Many players consider the Stella Montis Archives Key one of the most profitable keys currently available in the game. Some successful runs have rewarded players with rare gear such as the Aphelion weapon and even purple defensive battle augments, along with a large amount of valuables and crafting resources.
In fact, several raiders report leaving the room with more items than they could carry, even when equipped with high-tier looting augments.
If you happen to find the Stella Montis Archives Key during a raid in ARC Raiders, it’s usually worth the risk of heading to the Cultural Archives. The loot potential is extremely high, but remember that the location is also a hotspot for PvP encounters.
