Blue Archive’s crafting system lets players convert surplus resources into progression materials like Tech Notes, Gifts, and Furniture. Unlocked after completing Campaign Stage 3-2, it’s vital for upgrading students and enhancing your Café’s efficiency.

Crafting Room Explained

Two main functions define the Crafting Room:

• Material Synthesis: Uses Keystones for randomized rewards
• Material Fusion: Converts unwanted items into targeted resources

Accessible via the Base menu post-unlock, this system is essential for long-term progression.

Material Synthesis Breakdown

Three sub-nodes offer varying outcomes:

Standard Synthesis (Node 1)

• Cost: 1 Keystone
• Results: Random items like Credits, low-tier Furniture, or Tech Notes
• Best For: Quick resource grabs or when Keystones are scarce

Focused Synthesis (Node 2)

• Cost: 2 Keystones
• Results: Higher-grade materials or school-specific Tech Notes
• Best For: Targeting specific Furniture sets or school upgrades

Eleph Synthesis (Node 3)

• Cost: 5 Elephs (any student)
• Results: Chance for random Elephs
• Verdict: Avoid unless drowning in excess Elephs

Key Notes:

• One sub-node per roll
• Rolls reset after each use
• Processing time: 1–2 hours (acceleratable via Boost Tickets)

Keystone Sources

• Daily/Weekly missions
• Limited-time events
• Expired gacha pull conversions

Material Fusion Essentials

Transforms unused items into choice boxes using Fusion Keystones (distinct from regular Keystones).

Fusion Keystone Sources

• Joint Firing Drill rewards
• Shop purchases (limited quantities)
• Event milestones

Fusion timers mirror Synthesis—use Boost Tickets strategically to skip waiting periods.

Boost Ticket Management

Prioritize using tickets for:

• Tech Note Fusion (Unique Equipment farming)
• Rushing Café Furniture setups
• Critical Gift crafting for Bond progression

Ticket Sources

• Stage drops
• Event/raid shops
• Weekly missions

Warning: Never use Pyroxene or Total Assault currency for tickets.
