What to know
- Purple gear is the Cryston (T3) tier; only items that craft as purple will count.
- Gear uses four slots: Armor, Gloves, and two Kit pieces; crafting one per slot is the cleanest way to hit 4/4.
- Purple gear often bottlenecks on Cryston Components, so a stable production line matters more than menu navigation.
- If purple recipes are missing, it’s typically a progression/unlock issue (often tied to Authority Level).
In Arknights Endfield, this objective is best treated as a short factory sprint: make sure Cryston-tier inputs are flowing, then craft four purple outputs and finalize them through Gear Assembly so the tracker updates.

Quick reference
| Goal | What to do | Safe choice |
|---|---|---|
| Get 4/4 progress | Craft four purple (Cryston/T3) gear pieces | Armor + Gloves + Kit + Kit |
| Avoid wasted materials | Verify output rarity before crafting | Only queue recipes that show purple output |
| Prevent stalling | Ensure intermediate components are mass-produced | Keep a dedicated component line running |
Slot planning
| Slot | Craft target | Why it’s recommended |
|---|---|---|
| Armor | 1 purple Armor | Guarantees one slot is covered |
| Gloves | 1 purple Gloves | Fast to verify rarity and progress |
| Kit #1 | 1 purple Kit | Kits often craft quicker; good for “progress test” |
| Kit #2 | 1 purple Kit | Completes the four-slot count cleanly |
How the game counts “4 pieces” (and what qualifies)
A purple “piece of gear” means a crafted gear item whose rarity color is purple at completion. If a recipe outputs blue gear, it won’t count even if higher-tier materials were used somewhere in the chain.
There are four total gear slots in a standard loadout: Armor, Gloves, and two Kit pieces. The easiest way to avoid confusion is to craft exactly one purple item for each slot—this naturally equals four unique pieces and usually matches how quest tracking expects the objective to be met.
What to do if purple recipes or crafting are blocked
Two problems show up most often:
- Purple recipes don’t appear in Gear Assembly: This is usually a recipe unlock/progression gate. The fix is pushing progression until purple recipes become available, then returning to craft.
- Purple crafts stall mid-queue: This is almost always a parts throughput issue (intermediate components not produced fast enough). The fix is dedicating lines to the specific missing component(s), then resuming.
A quick way to confirm the system is working is to craft a single cheap purple Kit first. If the tracker increments, the pipeline and quest registration are fine—then it’s safe to commit to the other three crafts.
How to assemble 4 purple pieces (step-by-step)
Step 1

Open Gear Assembly and locate purple (Cryston/T3) recipes. Confirm the preview/output rarity color is purple before crafting anything.
Step 2

Choose four crafts that map to the four slots: 1 Armor, 1 Gloves, 2 Kits. Any set/non-set mix works as long as all four outputs are purple.
Step 3

Check required materials for those four recipes and identify the single biggest shortage (commonly Cryston Components). Set production to cover the shortage first, then let it run until the buffer is comfortable.
Step 4

Craft one purple Kit first as a “progress test,” then verify the objective increments to 1/4. If it does, proceed; if it doesn’t, stop and troubleshoot tier/collection/finalization.
Step 5

Queue the remaining three purple pieces (the second Kit, Gloves, then Armor). Craft order isn’t mandatory, but finishing cheaper pieces first reduces wasted time if something is wrong.
Step 6

Collect the completed pieces and finalize/assemble them in the gear interface until the tracker reaches 4/4.
“Not counting” troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Tracker stays at 0/4 | Crafted blue by mistake | Re-check the output rarity before crafting |
| Tracker doesn’t update after crafting | Items not finalized/collected | Collect finished crafts and finalize in Gear Assembly |
| No purple options in the list | Recipes not unlocked | Progress until purple recipes appear |
| Queue stops due to missing parts | Component production too slow | Build/dedicate a component line; avoid manual one-off batches |
Rewards and Progression Notes
This objective’s main payoff is questline progression plus having four usable purple pieces available for gearing Operators. In many Endfield objectives like this, the “reward” is more about unlocking the next tasks and enabling stronger loadouts than receiving a big one-time loot drop. Because reward packages can vary by quest step, region/build, and quest chain context, it’s safest to treat the guaranteed reward as: completion credit + four crafted purple items remaining in inventory/equipment options.
| Reward type | Guaranteed from completing this objective | Notes |
|---|---|---|
| Quest progression | Yes | Clears the objective and advances the related quest chain |
| Purple gear pieces | Yes (indirect) | The four crafted items remain available for equipping |
| Materials/currency bundle | Not reliably consistent | May vary by quest step/build; don’t assume a fixed payout |
| Access to stronger builds | Yes (practical reward) | Purple gear stats/bonuses improve combat performance |

Getting 4/4 without wasting time
The fastest, least error-prone method is crafting a full set of purple slots—Armor, Gloves, Kit, Kit—after confirming the output rarity is purple and the component pipeline won’t stall. If progress doesn’t register, the issue is almost always one of three things: wrong tier crafted, recipes not unlocked yet, or items not properly collected/finalized in the gear interface.
