This guide focuses on Final Fantasy XIV (FFXIV) Patch 7.41 and the Cosmic Exploration planet Ois. You’ll learn how crafter relic tool upgrades work on Ois, how to prioritize Data Set 6, and which mission types give the best time-to-reward so you can finish upgrades efficiently without wasting cycles (or materials).

How Ois Crafter Relic Progression Works (Cosmic Exploration Basics)

On Ois, crafter relic tools are upgraded by completing Stellar Missions and collecting “data” in numbered sets. The key change for this planet is the addition of Data Set 6, which is tied to higher-tier mission difficulty on Ois and is required in sizable amounts for the newest upgrades.

• You progress by doing missions and receiving data sets as rewards.
• Data Set 6 is the bottleneck for many players because it’s restricted to Ois missions of sufficient rank.
• Most efficiency decisions come down to choosing mission types that keep your data set totals balanced while emphasizing Set 6 when you need it.

Because mission rewards are fairly generous and spread across options, the “right” plan is less about hunting a single outlier mission and more about sticking to high-throughput choices consistently.

Fastest Overall Strategy: Farm A-Class Missions (Macro-Friendly)

For the majority of crafters, the fastest and least stressful approach is simple: focus on A-class Stellar Missions that reward the data sets you currently need (especially Data Set 6), and keep your loop steady instead of constantly rerolling or cycling mission lists.

Why A-class missions are the default best choice

• High consistency: Most A-class crafts are very manageable with modern endgame crafting gear.
• Macro viability: Nearly all A-class missions can be completed via macros, which stabilizes clear times and reduces mistakes.
• Good data density: Rewards are balanced enough that you can keep your sets aligned with minimal micromanagement.

In practical terms, this means you should pick A-class missions that match your current data needs and just keep crafting. The time you lose “optimizing” by constantly swapping missions often outweighs any tiny gain from perfect selection.

Data Set 6 Priority: How to Avoid the Common Progress Wall

Because Data Set 6 is new on Ois and required in large quantities, it’s the set most likely to stall your relic upgrades if you don’t watch it. A clean way to manage this is to treat Set 6 as your anchor and let other sets fill in naturally while you farm A-class missions.

• Check your research totals regularly (between batches of crafts, not after every single turn-in).
• When Set 6 is behind, choose A-class missions that award it until it’s back in line.
• When Set 6 is ahead, switch to A-class missions awarding whatever set is lagging.

This “keep it balanced” approach works well on Ois because there aren’t many extreme reward outliers for crafters. The goal is steady throughput, not a perfect spreadsheet.

The One Catch: Non-Macro A-class Missions (When to Avoid Them)

On each crafting job, there is typically one regular mission that doesn’t macro cleanly. If you’re not comfortable with expert-style decision crafting, skipping these is usually the correct call.

• If you rely on macros, avoid the non-macro mission and pick another A-class option that awards the same data set.
• If you enjoy expert crafting, these aren’t necessarily “hard,” but they do demand attention and can slow your average clear time if you’re not consistent.

Efficiency is about your average completion pace. A mission that’s theoretically better on paper can still be worse if it causes frequent reworks, failed crafts, or long deliberation.

Weather-Restricted Missions on Ois: Clear Skies and Clouds

Like other Cosmic Exploration zones, Ois has weather windows that unlock additional missions for a limited time. On Ois, the relevant conditions are Clear Skies and Clouds.

These weather-restricted missions are typically not macro-friendly, but they also aren’t tuned like the most punishing expert crafts seen in other zones. That makes them a realistic farming option for players who are comfortable crafting without a macro.

When weather missions are worth doing

• You can craft them reliably without failures (consistency matters more than peak speed).
• Your current data set needs align with the weather mission rewards (especially if it helps your Set 6 plan).
• You want Ois tokens alongside your data, making the session feel more rewarding overall.

How they compare to A-class mission farming

In terms of pure data-per-minute, weather missions tend to land in the same neighborhood as strong A-rank choices when executed cleanly. The big difference is that weather crafts often add token value on top of your data gains, which can matter if you’re also chasing collectibles or other Ois-related rewards.

Use the path that matches your crafting comfort and your tolerance for manual play. Both routes can complete Ois crafter relic upgrades quickly when you stay focused on Set 6 and avoid excessive mission cycling.

Path A: Macro-first (most players)

• Step 1: Identify which data set you’re currently short on (often Set 6).
• Step 2: Select an A-class mission that awards that set and is macroable for your job.
• Step 3: Craft in batches (for example, 5–10 turn-ins), then re-check your research totals.
• Step 4: Swap only when a different data set becomes the new bottleneck.

This is also the most predictable approach for budgeting materials. Predictability matters because crafting sessions can quietly consume a lot of resources, and replacing them through the Market Board can get expensive during patch spikes. Keeping a reserve of FFXIV gil helps you stay on-task when prices fluctuate.

Path B: Expert-first (weather windows + A-class filler)

• Step 1: Watch for Clear Skies or Clouds and pick the weather-restricted mission if its rewards match your needs.
• Step 2: Farm the weather mission while the window is up, prioritizing consistency over risky optimization.
• Step 3: When weather ends, return to macroable A-class missions to keep progress steady.

If you’re already comfortable with manual crafting, this path can feel smoother because you’re earning data and tokens in the same loop. Just be honest about your fail rate—one failed craft can erase the time advantage you were chasing.

Time Efficiency Tips That Actually Matter on Ois

Ois crafting is balanced enough that the biggest gains come from reducing downtime rather than hunting a secret “best” mission.

• Batch your crafts: craft multiple turn-ins before checking totals or swapping missions.
• Don’t over-refresh missions: cycling options repeatedly is usually wasted time unless you truly can’t craft what’s offered.
• Keep materials organized: empty inventory space and a clean retainer setup reduce friction.
• Plan for consumables: food, syrup/medicine, and repairs add up; many raiders and crafters keep a buffer for FFXIV gil for raid consumables and crafting sessions so they don’t have to stop mid-grind.

Cost Awareness: Materials, Repairs, and Market Board Spikes

Even if your mission clear speed is great, your overall progress can stall if you’re constantly stopping to restock. Ois relic crafting tends to coincide with higher demand for common crafting materials, which can push Market Board prices up.

• Repairs are a hidden drain during long sessions; expect durability and gear condition costs.
• Materia and meld adjustments can become relevant if you’re right on the edge of reliable clears.
• Market Board volatility is normal after patch content drops; consider stocking essentials ahead of time.

If you’re trying to minimize grind time rather than maximize it, some players look into options like how to get extra FFXIV gil without endless grinding so they can focus on crafting and progression instead of constant gathering loops.

• Over-optimizing mission selection instead of crafting consistently.
• Ignoring Data Set 6 until it becomes a hard stop.
• Forcing weather missions even when you can’t clear them reliably.
• Trying to “save gil” by under-prepping and then losing time to repeated restocks and repairs.

Ois is designed so that steady play wins. Pick a lane—macro or expert—and keep your loop clean.

Frequently Asked Questions

Do I have to do weather-restricted missions to finish Ois crafter relic tools?

No. Weather missions are optional. Macroable A-class missions are enough to complete upgrades efficiently; weather crafts are mainly a bonus route if you want tokens and can craft manually.

What’s the fastest way to get Data Set 6 on Ois?

Prioritize Ois A-class missions that award Data Set 6 and run them in batches. Don’t waste time cycling missions unless you can’t craft the offered options.

How much gil should I expect to spend while grinding these relic tools?

It depends on whether you self-supply. Costs usually come from materials, food/medicine, and repairs. Many players keep a cushion of Final Fantasy XIV gil so Market Board spikes don’t interrupt their crafting sessions.

Many A-class missions are achievable with solid mid-to-high end sets, especially with good macros and proper consumables. If you’re barely missing thresholds, small gear upgrades or better food can stabilize clears.

Is it worth buying materials instead of gathering everything myself?

If your goal is time efficiency, buying some inputs can be worth it—especially during short play sessions. This is often part of how to balance FFXIV gil spending between gear, glamour, and progression without burning out on farming.
