Blue Archive Gear Crafting Guide: What to Prioritize

Gear is the quiet half of a Blue Archive account. Levels and skills get all the attention, but a student sitting on T4 gear versus T7 gear is a different human being, and the gap only gets wider as you climb raid difficulties. The catch is that the systems feeding your gear are split across two places: a crafting chamber that mostly makes other stuff, and a blueprint farm that eats your AP one 10-point sweep at a time.

So here's the whole picture. How the crafting menu actually works, which tiers matter for raids, where to farm, who deserves the good stuff first, and the mistakes that torch your eligma.

How the Crafting Menu and Blueprint System Work

The Crafting Chamber

Crafting opens once you clear mission 3-2. You get two tabs, and they do very different jobs.

The first tab is Material Synthesis (the game calls the function "Generate" in some versions). You feed it Keystones and it rolls five random subnodes. You pick one, wait out a timer, and get a random item from that subnode's pool. Sometimes a subnode shows up gold. That one's holding something good: furniture from a guaranteed series, a superlative (purple, T4) material, student elephs, or credits.

There are three node slots you can open, and the price climbs fast:

| Node | What it costs to open | |---|---| | 1 | 1 Keystone, or 10 Keystone Pieces | | 2 | 2 Keystones, or 20 Keystone Pieces, or spare items/old furniture as filler | | 3 | 5 Eligma, or Keystones, or T3/T4 items and furniture as filler |

Node 2 is where the pool gets more specific. Instead of "some blu-ray disc" you can get a subnode tied to one school, like Trinity or Gehenna, which narrows results to that school's discs and notes. Node 3 goes further and can roll elephs, secret technical sheets, and raw credits.

The second tab is Tailor Made (Material Fusion). This one converts stuff you already own into raffle boxes and choice boxes, using credits plus Fusion Keystones from the Joint Firing Drill shop. Raffle boxes cost one material per box. Choice boxes cost two, and the choice box is the one that lets you pick the exact item, so it's the one that matters when you're one Gehenna tech note short of a skill-up. Trading ten off-school notes for five of the school you actually play is a fine deal when the leftovers were just going to sit there.

The part that trips people up

Here's the thing worth knowing before you dump Keystones anywhere: the crafting chamber does not make gear blueprints. Look at the node pools and you'll find growth materials, blu-ray discs, activity reports, OOParts, tech notes, weapon parts, gifts, cafe furniture, and elephs. No hat blueprints. No bag blueprints.

Gear comes from the blueprint system that lives on each student's equipment screen. Every student has three gear slots with fixed item types, and which types they get is preset, so one student's first slot is a hat and another's is gloves. Gear tiers run T1 through T10. You get the T1 base piece from a drop, then every tier after that costs blueprints of that tier plus credits. Each student needs their own set, so a bag given to Tsubaki is not a bag Hoshino can borrow.

One newer addition worth knowing: Universal Blueprints. These came to the Japanese server in April 2026 and Global in August 2026, and they substitute for any tier of the matching blueprint type. The exchange rate is steep at the top:

| Blueprint tier | Universal Blueprints needed | |---|---| | T1 | 1 | | T2 | 2 | | T3 | 3 | | T4 | 5 | | T5 | 7 | | T6 | 10 | | T7 | 15 | | T8 | 20 | | T9 | 30 | | T10 | 50 |

The game burns regular blueprints first, then choice tickets, then Universals, so you won't accidentally waste the rare ones on a T3.

Which Gear Tiers Matter for Total Assault and Grand Assault

Why raids are the measuring stick

Total Assault unlocks after clearing 4-1 and runs for a week every other week. One boss, one armor type, a ladder of difficulties from Normal up to Torment. Grand Assault (Elimination Raid) is the meaner cousin: the same boss shows up in three armor types, you get a separate ticket for each, and you hold up to seven tickets per type, earning one per day you log in during the season. Two of the three armor types go all the way to Torment and one stops at Insane.

The reason gear tiers matter so much here is that raid score is damage plus survival on a timer. A higher tier hat is a bigger attack number and more crit damage. A higher tier bag is a pile of flat HP that keeps your front line standing through a boss AoE. The coin payouts scale with difficulty too, and those coins buy elephs and secret tech notes in the raid shop. Insane pays 140 coins plus 40 rare coins per clear, Torment pays 160 plus 60.

The stat jumps worth aiming for

Not every tier is equal. Here's the attack slot at a glance, using the hat line since it's the biggest raw damage piece:

| Tier | Attack | Crit Damage | |---|---|---| | T4 | 20-25% | 400-800 | | T5 | 27-30% | 900-1200 | | T6 | 31-35% | 1250-1600 | | T7 | 36-40% | 1600-1800 | | T9 | 46-48% | 2000 | | T10 | 49-50% | 2000 |

Notice where the returns flatten. T9 to T10 on a hat is three-ish percent attack and zero extra crit damage. That last tier is a luxury. Meanwhile T4 to T7 is sixteen points of attack and a doubling of crit damage, which is why getting a student off T4 should be your first big push.

The HP slot tells a similar story with bags:

| Tier | Max HP | Defense | |---|---|---| | T4 | 1500-1875 | 500-1000 | | T6 | 3750-5500 | 1100-1200 | | T7 | 5700-7500 | 1200-1300 | | T9 | 10000-12000, plus 2-5% HP | 1400-1600 | | T10 | 12500-14000, plus 5% HP | 1600-1700 |

A T4-to-T9 bag is roughly seven times the flat HP. That's the difference between a tank eating a Binah laser and a tank getting deleted by it.

What a realistic target looks like

For difficulty context: Extreme and below is very forgiving, and a roster in T5-T6 gear with sensible levels clears it. Insane wants proper investment, usually T7 to T8 across the board on your main raid squad plus skills that are actually raised. Torment is where accounts in T9 and T10 gear live, often with high star levels and unique equipment on top. Clear videos for Insane and Torment runs almost always show T9 or T10 in all three slots, so don't beat yourself up if you're not there. Getting every student you actually use to T7 is a solid, reachable goal, and it carries you through Insane on most bosses.

One raid-specific note: crit stats are king in raids because boss fights are long enough for crits to average out. Watches (crit rate plus crit damage plus HP) and charms (crit rate plus crit resist lines) pull way more weight there than they do in story missions, where fights are short and enemies die to raw attack.

Crafting Materials and Where to Farm Them Efficiently

Keystones and Fusion Keystones

Keystones come from daily and weekly missions, plus a steady trickle from events. There's also a gacha conversion most people forget about: pulls that don't go toward a spark convert into Keystone Pieces at the end of a banner period. If you're pulling at all, you have more of these than you think. Check the total before you assume you're broke.

Fusion Keystones are different. Those come from the Joint Firing Drill shop, which only restocks when a new Drill runs, so buy them during the event instead of realizing later that you're empty.

For the crafting chamber itself, the community consensus is simple: open node 1, stop there. Node 2 can be worth it when you're chasing something specific like a school's tech notes or a furniture set for your cafe, since the pool narrows down. Node 3 costs eligma, and eligma has much better uses. More on that below.

Gear blueprints

Blueprints drop from Normal missions. Every run costs 10 AP, every stage drops a fixed set of gear types, and the item listed leftmost in a stage's drop list has the best rate. Two rules make the farm way less painful:

• Higher stages also drop lower tiers. A stage that lists a T6 bag will hand you T4 and T3 bags at reduced rates on the same runs. So farm the highest tier you need and let the lower ones come along for the ride.
• Farm stages that drop two or three things you actually want. Ten AP that feeds a hat and a glove at once is twice as efficient as ten AP feeding one piece.

A few classic stages people sweep on purpose: 10-4 is the go-to for T4 bag blueprints, which turns every tank that can wear one into an absolute unit. Around 13-1, 13-3, and 13-4 you're into T5 pieces with T3 and T2 riding shotgun. Later areas keep that pattern going all the way up the ladder, so the highest area you've cleared is usually where your AP belongs.

Hard stages are a different farm. Those cost 20 AP and mainly pay out student elephs, with gear drops tagging along. Don't sweep hards for blueprints when normals do it at half the cost.

Timing the farm

Double drop campaigns on Normal missions are the single best time to grind blueprints. Same AP, twice the drops, and it's when buying the daily enhancement stone and blueprint stock from the normal shop actually makes sense. Event shops deserve a look too, since many events sell gear-related stock directly for event currency, and event currency per AP usually beats raw mission sweeping.

The other half of timing is just not spending AP on commissions. Outside of double commission drops, the standard advice is to run the cheapest one for the daily and put everything else into missions or events.

Prioritizing Gear for Your Strikers vs Your Support Team

Strikers first, almost always

Your front six take the field and do the fighting, so your front six get the blueprints. The attack slot comes first for damage dealers, and here's how the three options break down:

• Hats give the most attack and add crit damage from T4 on. This is the damage dealer piece.
• Gloves give about 5% less attack than hats across most tiers but add crit rate and accuracy, catching up by T10. Better for students who crit-fish or who need to actually land hits.
• Shoes give the least attack but tack on HP. Fine for bruisers, wrong for your carry.

Back row Specials matter too, they just need different things. A tank or off-tank in the special slot wants bags (flat HP plus defense) or badges, which give the biggest HP lines in the game plus healing-received and evasion. A healer wants the necklace line, since that's the piece with healing power and CC strengthening on it. Watches and charms sit in the third slot and round out crit stats or crit resistance depending on the student.

Who gets the eligma

Eligma is the rare currency you get from gacha dupes and a few other places, and you spend it in the shop on character elephs to raise star levels, or on unique equipment. The standard order, and one the community argues about less than you'd expect: main damage dealers first, then tanks and healers, then supports last if ever.

The logic is straightforward. Star levels pump attack and crit into the students whose whole job is dealing damage, and raid score is damage. A dealer going from 3-star to 5-star with UE investment is often a bigger jump than a whole gear tier. Supports like Ako do get value from stars, but it's smaller and she works fine without it. And an important rule from the eligma shop: only buy elephs for students who are limited or unfarmable. If a hard node already drops their elephs, you're paying premium currency for something AP gives you for free.

A decent working order for a full build-out on one student: attack slot to your current max tier, then the HP slot, then the third slot, with skills raised alongside rather than after. Skills first is honestly the right call for a dealer you just pulled, since EX skill levels are cheap relative to their payoff. Gear pulls ahead once the skills you actually use are capped for your level.

One last thing that saves a ton of resources: club borrowers. You can borrow students from clubmates for raids, and they show up with whatever gear their owner gave them. Borrowing a maxed dealer for a Binah week costs you nothing but club membership, which you unlock by clearing 3-4. Visit the club daily for 10 free AP while you're at it.

Common Crafting Mistakes That Waste Eligma and AP

Opening the third crafting node

Five eligma for a chance at random elephs from a pool you don't control. Eligma buys specific elephs in the shop for a known price, and it buys star levels for students you've chosen on purpose. Don't hand it to a slot machine. Even node 2 is a "sometimes" purchase, and node 1 alone is what most long-term players run every single time.

Buying elephs for farmable students

Covered above but it deserves a second mention because it's the most expensive version of this mistake. Check whether a student has a hard node or a shop that sells their elephs before you touch eligma. Limited banner students are the real candidates, plus anyone you need for a specific raid team and can't wait on.

Farming low stages for low tiers

If you need T4 blueprints, run a stage that drops T5 or T6. The lower tiers come as bonus drops. Newer players end up short on T2 and T3 precisely because they skip ahead, and the fix is the same: sweep the highest stage you can, since those older tiers fall out of it anyway. Going back to an early area to farm T2 directly is the slow way around.

Spreading blueprints across the whole roster

Twenty students at T4 lose to six students at T7, every time, in every mode that matters. Raids only field six at once plus your specials, and story content is clearable with a focused core. Pick your main raid squad, push them, and let the bench sit in whatever dropped for free. The urge to click upgrade on everyone is strong and the game will absolutely let you do it.

Ignoring double drops and events

Blueprint farming during a dry patch is fine. Blueprint farming during a Normal mission double drop event is twice as good, and it happens often enough that patient players save their pyroxene AP refills for it. Same logic for events: an event shop selling what you need usually beats the mission list for value per AP.

Buying booster tickets from the raid shop

The crafting timer is real but harmless. Come back in a few hours, the item's still there. Raid coins are for elephs, secret tech notes, and skill materials for students you're about to use in the next raid, and the folks who've done the math all land on the same answer: the tickets are a trap.

Skipping the cafe loop

It's not a crafting mistake exactly, but it starves the whole system. More cafe furniture means a better cafe rank, and a better rank means more passive AP per day. More AP, more sweeps. Crafting furniture early on is legitimately one of the best uses of the chamber, and clearing missions 2-1, 3-5, 6-5, 9-5, 12-5, 15-5, and 18-5 hands you the cafe upgrade cores. Gift crafting comes right after, since bond levels gate each student's unique equipment.

If you take one ordering rule away: skills and levels on your main six, then gear tiers on that same six, then widen the circle. The blueprints will keep dropping. The eligma is the part you can't get back.
