Legendary Blueprints in ARC Raiders unlock some of the most powerful weapons, attachments, and unique items in the game. These blueprints are often tied to specific maps, weather modifiers, elite enemies, or hidden puzzles, making them highly sought after by experienced players. Below is a complete breakdown of every Legendary Blueprint, where to find them, and the best strategies to obtain each one efficiently.

Kinetic Converter Blueprint

The Kinetic Converter is a Legendary weapon attachment that increases your weapon’s rate of fire by 15%, significantly improving time-to-kill in PvP. The trade-off is increased vertical and horizontal recoil, but in skilled hands, it’s one of the strongest attachments available.

You can find the Kinetic Converter most consistently on the Dam Battlegrounds map. Your chances improve during Cold Snap, Night Raid, or Electromagnetic Storm conditions. Head to the Control Tower, take the zipline to the top, breach the roof door, and locate the hidden ladder section. Carefully drop onto the side platform near the ladder where one or two breachable crates can spawn. These crates have a chance to contain the blueprint.

Anvil Splitter Blueprint

The Anvil Splitter is a Legendary attachment exclusive to the Anvil Revolver, transforming it from a single-shot weapon into a four-pellet burst similar to a mini shotgun. This makes it devastating at close range but weaker at long distances.

This blueprint is commonly found in the Pharmacy Building on the Buried City map. To maximize drop rates, load into raids during Cold Snap or Night Raid conditions. Loot every drawer inside the pharmacy, as this building has one of the highest attachment spawn rates in the game.

Snap Hook Blueprint

The Snap Hook allows players to grapple onto ledges or latch onto nearby ARC units, providing unmatched mobility and traversal options.

The best place to find the Snap Hook blueprint is Dam Battlegrounds, particularly during Electromagnetic Storm conditions. Search the Research and Administration Building, focusing on desk drawers on the top floor. While it can also appear on Bluegate, Dam Battlegrounds offers more consistent results. Additionally, a fully built Snap Hook (not a blueprint) can occasionally spawn in the Buried City pharmacy during Cold Snap events.

Aphelion Legendary Weapon Blueprint

The Aphelion is a Legendary burst-fire weapon that excels against enemy raiders and performs best in PvP scenarios.

There are two ways to obtain this blueprint. The first is defeating the Matriarch during a Matriarch event as a solo player and looting her core immediately after death. This method is highly competitive and risky. The recommended method is looting Cella Montis, preferably during a Night Raid. The blueprint can spawn in drawers, trash cans, and containers throughout high-value loot areas such as the loading bay and atrium.

Equalizer & Jupiter Blueprints

The Equalizer is a powerful Legendary minigun ideal for stripping armor from massive ARC enemies like the Queen and Matriarch. The Jupiter is a charge-up sniper rifle, offering high damage but slower pacing.

Both blueprints are obtained by completing the Harvester Event, which appears on maps with the Harvester condition. Enter the Harvester, locate three power cells, insert them into the central column, and destroy all yellow control nodes to complete the puzzle. Upon completion, loot containers emerge from the center, which may contain either blueprint. Be prepared to avoid fire bursts and electric shock attacks during the event.

Queen & Matriarch Reactors (Crafting Materials)

While not blueprints, Queen Reactors and Matriarch Reactors are essential crafting components for Legendary weapons like the Equalizer, Jupiter, and Aphelion.

To obtain them, damage the Queen or Matriarch until their armor plates break off. Looting these plates gives a high chance of receiving a reactor. Using smoke grenades allows you to safely loot armor plates even while the boss is still alive, though this is extremely risky.

Guitar Legendary Item (Secret Blueprint Reward)

The Guitar is a unique Legendary cosmetic item unlocked by completing a hidden puzzle on the Buried City map. Players must locate and press 15 hidden buttons across the map in the correct order. Pressing a button out of order resets the entire puzzle.

Once all buttons are activated correctly, a hidden loot room unlocks, allowing you to claim the Guitar and other bonus items. This is one of the most time-consuming but rewarding Legendary unlocks in ARC Raiders.

Final Tips for Legendary Blueprint Farming

Legendary Blueprint farming in ARC Raiders heavily depends on map conditions, loot locations, and event knowledge. Prioritize Night Raids, Cold Snap events, and Electromagnetic Storm modifiers, and always fully loot high-value buildings. Mastering these strategies will dramatically increase your chances of securing every Legendary Blueprint in the game.
