Crafting in Blue Archive lets you turn excess resources into useful progression materials like Tech Notes, Gifts, Furniture, and even Elephs. It unlocks after clearing Campaign Stage 3-2 and becomes one of the most flexible systems for upgrading students and your Café.

This in-depth guide explains exactly how crafting works, when to use each node, what to avoid, and how to manage Crafting Boost Tickets and Keystones effectively.

Crafting Room Overview

The Crafting Room has two systems: Material Synthesis and Material Fusion. Both use different resources and timers, and both are essential for long-term account progression.

You can find the Crafting Room in the Base menu after unlocking it through the main story.

Material Synthesis

Material Synthesis uses Keystones to generate randomized crafting outcomes across three sub-node levels.

Node 1: Standard Synthesis

• Cost: 1 Keystone

• Access: Only first sub-node

• Result: Random pool of items like Gifts, Tech Notes, low-grade Furniture, or Credit Boxes

• Use When: You’re low on Keystones or just want a quick material

Node 2: Focused Synthesis

• Cost: 2 Keystones

• Access: Second sub-node unlocks

• Result: Smaller pool of more specific items (e.g., Furniture types, higher-grade materials)

• Use When: Targeting a resource pool like Furniture or school-specific Notes

Node 3: Eleph Synthesis

• Cost: 5 Elephs (of any student)

• Access: Third sub-node unlocks

• Result: Includes a chance to receive random Student Elephs

• Use When: Almost never. This node is inefficient and consumes rare currency.

Important: You can only select one sub-node per roll. The list resets with every use.

Crafting Time: Each roll takes time to complete (typically 1–2 hours).
Boost Tickets: You can skip the timer with a Crafting Boost Ticket. Costs increase depending on which node you used.

Where to Get Keystones

• Daily and Weekly Missions

• Story Events

• Unused Gacha Pulls (converted after banners end)

• Certain login bonuses and bundles

Material Fusion

Fusion lets you convert unwanted items into better ones. You’ll need Fusion Keystones, which are not the same as regular Keystones.

Fusion Basics

• Cost: Fusion Keystone specific materials

• Ratio: 2:1 conversion (10 items make 5 higher-grade items)

• Examples:

  • 10 Gehenna Notes → 5 Gehenna Note Choice Boxes

  • 10 gifts → 5 Gift Boxes (selectable)

  • Mixed Furniture → specific piece

Fusion is the only way to transform Tech Notes and Gifts into choice boxes, which let you target exact schools or item types.

Where to Get Fusion Keystones

• Joint Firing Drill rewards

• Purchased from Shop (limited stock)

• Event milestones or bundles

Crafting Time

Just like Synthesis, Fusion also has wait times. More items = longer queues. You can use Crafting Boost Tickets to skip these as well.

Crafting Boost Ticket Strategy

Boost tickets are best saved for:

• Fusion of Tech Note Choice Boxes (for Unique Equipment grinding)

• Furniture rushes during early Café setup

• Urgent Gift crafting (for Bond levels and skill unlocks)

You get these from:

• Stage drops

• Event shops

• Raid shops

• Weekly missions

Do not spend Pyroxene or Total Assault currency on them.

What To Craft First

Early Game

• Furniture: Boosts AP and Credit passively from the Café

• Gifts: Increases Bond level → unlocks Unique Equipment use

• Low-cost Fusion: Turn spare Notes into your school’s choice box

Mid Game

• Tech Notes: Prioritize schools like Trinity, Gehenna, Millennium

• Gift Boxes: Choose gifts for meta students

• Fusion into choice boxes: More efficient than raw farming

Late Game

• Unique Equipment push: Fusion for massive amounts of Tech Notes

• Spare Keystones: Synthesize Gifts or Credits during downtime

• Craft to prep for events: Make Gift reserves before seasonal Bond walls

Optimization Tips

• Log in every day: Crafting timers run even while you’re offline

• Don’t hoard Fusion Keystones: They’re limited, but meant to be used

• Always check sub-nodes: Sometimes node 1 gives what you need

• Save Elephs: Never use node 3 unless you're at extreme overflow

• Auto-complete Fusion only when high-priority — like for daily tasks

Final Blurb

Blue Archive’s Crafting system is easy to ignore at first, but critical once you hit gear and Bond bottlenecks. Synthesis is best for rolling extras, while Fusion converts junk into precision. If used wisely, you’ll skip weeks of stage farming just by managing Keystones and boost tickets.

FAQ

How do I unlock crafting?

Clear Main Story 3-2 to access the Crafting Room.

Is node 3 worth using for Elephs?

No. It costs too much and gives random results. Save your Elephs for shop unlocks.

How do I get more Crafting Boost Tickets?

Stage drops, events, Total Assault exchange, and login rewards. Don’t buy them with premium currency.

What should I craft early on?

Focus on Furniture and Gifts. Both improve progression and unlock student power boosts.

Is Fusion better than farming?

Yes, when you're converting unused materials into specific targets like school choice boxes.
