The Matriarch Reactor is a legendary, recyclable material. It is not a weapon or consumable; its purpose is to be broken down into high‑value crafting components or sold for credits. You only obtain it by defeating the Matriarch, a limited‑time world boss.

How to get the Matriarch Reactor (Matriarch event)
The Matriarch is a roaming ARC war machine that appears only when its map event is active. It can spawn on any ARC Raiders map while the event is live. The encounter was introduced with the North Line update; an early spawn issue was addressed, and the boss now appears normally whenever the event condition is active.
| Encounter aspect | Details |
|---|---|
| Availability | Limited-time event; appears when the Matriarch condition is active on a map |
| Maps | Can occur on any map while the event is live |
| Threat profile | Heavily armored; fires explosive rockets and area gas grenades |
| Weak point | Central core; coordinate to draw aggro and create clean angles on the core |
| Reinforcements | Summons additional ARC units; aggro management is key |
| Loot behavior | Armor pieces can drop loot mid-fight; the main chassis yields the best rewards on kill |
Notable items in the Matriarch’s loot pool include the Reactor itself and a range of ARC crafting materials.

Recycling vs salvaging the Matriarch Reactor
The Reactor is designed to be broken down. You have two options: recycle it for a full component set or salvage it for a partial return.
| Action | Yield per 1 Matriarch Reactor |
|---|---|
| Recycle | 1× Power Rod, 1× Magnetic Accelerator |
| Salvage | 1× Power Rod |
Recycling produces both a Power Rod and a Magnetic Accelerator, making it the higher-yield option when you need late‑game components. Salvaging returns only the Power Rod and can be used if you do not require a Magnetic Accelerator.

Carry weight and economy considerations
With a weight of 10.0 and a stack size of 1, the Reactor is bulky and occupies its own slot. Plan your inventory around the event if you expect multiple drops. If you are short on materials, recycling is the value play thanks to the extra Magnetic Accelerator. If you are flush with components and need currency, the flat 13,000 Raider Credits sell price is a simple conversion.
In short: use recycle when you need both components; use salvage only if you want a Power Rod without the extra part; sell when credits matter more than materials.
