Arknights Endfield: How to Assemble 4 Pieces of Blue Quality Gear

Hey, Endfield trailblazers! Stuck on that nagging Operational Manual Node 08 challenge: “Assemble 4 pieces of blue quality gear”? This mid-game hurdle rewards you with Cast Die x6 and Operational EXP x180 (plus node completion goodies like Oroberyl and more). Blue gear (Tier 2 rarity, typically Level 36) is your ticket to powering up Operators with solid stat boosts like defense, primary/secondary attributes, and potential set bonuses. No need for a full set—just craft any four pieces (armor, gloves, and kit piece x2) via your AIC factory. Here’s your no-fluff guide to smash it.

Quick Prerequisites

Before diving in, tick these off:

• Story Progress: Reach Originium Science Park in Act 1 (unlocks prime Ferrium Ore farming spots).
• Authority Level: Hit level 39 to unlock blue gear recipes (rewards from progression).
• AIC Unlocks:
• Mining III node for Electric Mining Rig Mk. II (essential for Ferrium; craft initial ones manually if needed).
• Outfitting I for Operators to equip Level 36 gear (optional for this task).
• Power Grid: Expand with power relays for miner power draw (Mk. II uses +5 power).

Pro Tip: Manually mine initial Ferrium Ore to bootstrap your first Mk. II rig: 1 Portable Originium Rig (5 Origiocrusts) + 10 Ferrium Parts.

Required Materials (Per Gear Piece, Approx.)

Crafting one blue piece needs Ferrium Components and Decryption Crystals. Stockpile for 4x!

Step-by-Step Guide to Assembly

Step 1: Farm Ferrium Ore Access

• Head to Originium Science Park (story unlocked): Prime nodes at entrance road, west of Transport Nexus, south of Research Center, and north of Mountain Path Slope.
• Early spot: East of Core AIC in Valley IV (small field for bootstrapping).
• Deploy Electric Mining Rig Mk. II on nodes (route belts to storage). Power up your grid first!

Step 2: Build the Production Chain

Enter AIC Mode > Factory layout:

1. Mine → Ferrium Ore to storage.
2. Refine → Ferrium Ore → Ferrium (Refinement Unit).
3. Gear → Ferrium + Origiocrust → Ferrium Components (Gearing Unit).

• Factory ticks every 2 s—optimize belts to avoid jams!

Step 3: Stockpile Decryption Crystals

• Farm via combat: Defeat enemies anywhere (prioritize story/dailies). You’ll need ~100+ for 4 pieces.

Step 4: Craft in Gear Assembly

• AIC > Gear Assembly tab (lower-right).
• Select the unlocked blue recipe (e.g., Armor, Gloves, Kit).
• Input: Ferrium Components + Decryption Crystals.
• Craft 4 pieces (any combo). Boom—task complete! No equipping required.

Step 5: (Optional) Equip & Bonus Hunt

• Assign to operators for stats/set effects (3-piece bonus activates).
• Artifice later: Sacrifice same-rarity gear and catalysts for stat upgrades (risky, but powerful).

Killer Factory Blueprints (Import Codes)

Skip manual building—import these for blue gear pipelines (server-region match required, e.g., NA/US):

• Self-Sufficient Early-Mid (up to Ferrium/Blue): EFO019A61iO6UaeU5uI2
• High-Crystal (Efficient Blue+): Check community sites like endfieldtools.dev for more.
• AIC > Blueprint > Import Code.

Common Pitfalls & Tips

• No Components? Pipeline bottleneck—reroute belts, add more miners/refiners.
• Power Shortage? Build Generators/Relays.
• Recipes Missing? Grind Authority Level via missions.
• Slow Farm? Auto-miners are better than manual; focus on the Science Park cluster.
• Visual Aid: YouTube “Endfield blue gear factory” for layouts (e.g., GuidingLight vids).
• Save the blueprint before tweaks—resets are free.

Nailed it in 20-30 mins with a good setup. Blue gear bridges you to purple—keep pushing those factories! What’s your go-to blueprint? Share below.
