Step-by-Step

Step 1 — Understand Your Crafting Queue Limits

When you first unlock crafting, you might not realize that your crafting queue is limited. Here’s how it works:

1. Default weapons queue: 3 slots open immediately.
2. Additional slots: Buy expansion packs from the Campus Life Division Shop for 500 gems each (up to 10 total slots).
3. Equipment queue: Separate from weapons — 2 slots default, expandable to 6 with gem purchases.
4. Prioritize your queues: Don’t waste slots on weapons you won’t use. Always craft what you need for your main teams.

Pro tip: Keep at least one slot reserved for event-exclusive weapons. They often have time-limited bonuses.

Step 2 — Gather Materials Efficiently

This is the bread and butter of crafting. Here’s the best order to farm:

Priority	Activity	Materials Earned	Notes
🥇	Daily Quests	All basic ores, leather, cloth	Do ALL dailies — they add up fast
🥈	Scrap Collection Missions	Iron Ore, Steel, Gold	3 stages available, clear all
🥉	Campus Defense (CD)	Weapon fragments, mats	Best source for weapon-specific mats
4	Challenge Quests	Rare materials, tokens	Requires higher power — unlock early
5	Event Stages	Event-specific materials	Time-limited — farm hard while active
6	Friend Material Gifts	Mixed materials	Add active players as friends

The 6.0 Patch Update: Patch 6.0 added new challenge quest routes that grant 50% more weapon fragments for Platinum-tier weapons. Make sure you’re using the new routes — they’re labeled with a ★6.0 badge in the mission select screen. Additionally, Erika’s debut celebration has introduced a special limited-time coupon that doubles material drop rates in scrap collection for 7 days. Keep an eye on the in-game notices!

Step 3 — Craft Your Weapons in the Right Order

Don’t just craft whatever’s in your queue. Follow this priority system:

Phase 1 — Foundation (New Players)

1. Craft a solid sub DPS weapon for your main team’s second slot
2. Craft a sturdy tank weapon for your front line
3. Save your rare materials — don’t waste them on low-tier gear

Phase 2 — Mid Game (Friend Rank 5+)

1. Upgrade weapons with Weapon Fragments for stat increases
2. Start investing in Mastery Tokens on your top 3 weapons
3. Craft a support/utility weapon for harder content

Phase 3 — Endgame (Max Friends, Event Grinded)

1. Target specific meta weapons — check the latest tier lists
2. Push Mastery to Lv. 10 on every main DPS
3. Craft gear sets for set bonuses that synergize with your teams

---

Step 4 — Upgrade Skills Smartly

Skill enhancement can drain your credits fast. Here’s how to spend them wisely:

• Do NOT max all skills at once. Pick 3–4 main characters and invest fully.

• Priority order for skill upgrades:

  1. Ultimate skill damage boost
  2. Skill cooldown reduction
  3. Passive stat bonuses
  4. Support/heal skill enhancements

• Skill Upgrade Materials drop from the dedicated skill stage — make this your daily farming target before touching other systems.

• Event 6.0 Note: The new Erika-themed skill stages grant bonus Purple Crystal Shards, which can be exchanged for skill upgrade materials at the event shop. If Erika is in your rotation, this is free money.

---

Step 5 — Use the Exchange Shop

You WILL accumulate duplicate weapons and equipment. Here’s how to handle it:

1. Go to Shop > Exchange

2. Convert duplicates into Crystals, Weapon Fragments, or Skill Materials

3. Recommended conversion targets:

   • Low-rarity duplicates → Crystals (save for gacha)
   • Duplicate SSR weapons → Weapon Fragments (always valuable)
   • Duplicate equip sets → Gem coupons or event tickets

4. The exchange also offers Mastery Token packs — buy these when they appear in rotation!

Step 6 — Master Memory Cube Combining

Memory cubes are how you unlock additional skill memory slots, which is essential for swapping builds on the fly.

• Collect Memory Cubes from the dedicated stage (drops ~20/day with consistent play)
• Combine 3 common cubes → 1 rare cube
• Combine 3 rare cubes → 1 epic cube
• Use epic cubes to unlock +1 memory slot (costs 10 epic cubes per slot)
• Maximum extra slots: 5 (total 6 including the base)

Budget your cubes! Don’t unlock all slots at once — pace it so you can keep up with meta shifts.

---

Step 7 — Take Advantage of Event Crafters

Every major event introduces special crafting recipes not available outside the event window. These often include exclusive weapon skins, bonus stat modifiers, and limited-time materials. Here’s how to prepare:

1. Check event shop rotation before the event starts
2. Stockpile event coins during the first week when demand is low
3. Craft priority items first — event-exclusive weapons usually outperform regular ones
4. Save tickets for high-rarity recipes rather than spending them early

The Erika event (2026) is no exception. New recipes include the Crimson Blossom Blade weapon and Memory Crystal gear sets that provide massive burst damage bonuses. Farm those event coins aggressively.
