What is a Sentinel Firing Core?

Sentinel Firing Core

The Sentinel Firing Core is a rare drop from a specific ARC enemy type called the Sentinel. These upgraded turret-like machines are deadly, firing powerful single shots that can drain your shield instantly. You’ll mainly use this item to upgrade your Gunsmith Station to Level 3, but you can also recycle it for valuable crafting materials:

2 ARC Alloys
3 Mechanical Components

Where Sentinels Spawn (Reliable Locations)

Sentinels don’t appear everywhere. They’re fixed to structures or guard specific points of interest. The two best places to find them include:

Dam Battlegrounds – Research & Administration Building: Check the top of the blue staircase along the main building. This is the most reliable spawn area.
Blue Gate – Pilgrim’s Peak and Headhouse: Sometimes spawn on top of the main structure or within the Headhouse near the Outer Gates.

How to Fight and Loot Sentinels Safely

Sentinels pack a punch. If you want to survive their sniper-like attacks, keep these strategies in mind:

Use cover to dodge their heavy shots and return fire safely.
Maintain distance or high ground for better visibility and protection.
If you shoot from an elevated spot, their loot might fall down — move carefully to avoid fall damage.
Act fast when looting; destroyed Sentinels can despawn or be looted by others.

Other Ways to Get Sentinel Firing Cores

Besides farming Sentinels directly, you can also find Sentinel Firing Cores through these methods:

Loot Arc Husks: Destroyed Arc Husks and Arc Courier Husks sometimes drop Sentinel Firing Cores. Look around Dam Battlegrounds — especially the Swamp Outpost and nearby Baron Husks.
Check Destroyed Sentinels: Even if another Raider takes one out, you can still search the husk for drops.
Buy Sentinel Firing Cores at BuyMMOG: You can also purchase Sentinel Firing Cores safely from BuyMMOG. Make sure to verify seller reputation and review terms before purchasing to avoid any issues.
