What Is Ruby Bolete and Why It’s Critical?

Ruby Bolete is a rare 4-star upgrade material that controls your mid-to-late game progression in Arknights Endfield. Once your operators reach level 60, they cannot advance further without this precious resource. Even with full EXP bars, the level cap remains locked until you gather enough Ruby Bolete for promotion.

The lore describes Ruby Bolete as a dangerous fungus – “Every year, many frontier settlers would suffer multiple organ failure caused by ruby bolete poisoning.” This explains its rarity and why it’s only found in specific, dangerous areas of the game world.

Prerequisites Before Hunting Ruby Bolete

Before you can start collecting Ruby Bolete, you must meet these requirements:

Complete Valley Forest Story Progress
- Finish the main story up to Valley 4
- This unlocks the transition to new areas
Unlock Wuling Map
- Automatically unlocked after completing Valley 4
- New region with different resources and challenges
Have Level 60 Operators
- At least one operator must reach level 60
- This triggers the need for Ruby Bolete

Without meeting these conditions, Ruby Bolete won’t appear anywhere in the game world.

Ruby Bolete Location: Jingyu Valley in Wuling Map

Ruby Bolete exclusively spawns in Jingyu Valley, the first region of the Wuling Map. Here’s exactly where to find them:

Location Details

Primary Spawn Points:

Spot 1: Near the teleport node before Wielding City
Spot 2: Across the small river from Spot 1
Both are marked as “Rare Growth Nodes” on your map

Visual Identification:

Large red mushroom with glowing properties
Distinct from smaller plants and regular mushrooms
Easy to spot once you know what to look for

Collection Strategy

First Visit (Best Yield):

Spot 1: 10 Ruby Bolete
Spot 2: 10 Ruby Bolete
Total: 20 Ruby Bolete immediately

Daily Farming:

Each spot respawns 1 Ruby Bolete per day
Maximum yield increases with Exploration Level
Consistent daily farming is crucial for progression

Advanced Farming Techniques

1. Mark Your Map

Place custom markers on both spawn locations
Create efficient farming routes
Save time on daily collection runs

2. Optimize Daily Routine

Collect immediately after daily reset (server time)
Combine with other Wuling Map activities
Plan your route to minimize travel time

3. Exploration Level Benefits

Higher Exploration Level increases maximum yield
Focus on exploring Jingyu Valley thoroughly
Complete side quests and discover hidden areas

Alternative Acquisition: Growth Chamber Cultivation

For players who prefer passive income, Ruby Bolete can be cultivated:

Requirements

Cabin Level 3 minimum
Access to OMV Dijiang facility
Ruby Bolete Mycelia formula (unlocks at Cabin Lv.3)

Cultivation Process

Navigate to OMV Dijiang
Access the Growth Chamber
Select Ruby Bolete Mycelia cultivation
Wait for growth cycle completion

Common Mistakes to Avoid

1. Early Game Searching

Ruby Bolete doesn’t spawn in Valley Forest or early game areas. Don’t waste time searching there before unlocking Wuling Map.

2. Ignoring Daily Resets

Missing daily respawns significantly slows progression. Set reminders for collection times.

3. Poor Resource Management

Using Ruby Bolete on low-priority operators can halt your main team’s progression.

4. Neglecting Exploration Level

Higher exploration levels increase yields, making farming more efficient.

FAQ’s

How many Ruby Bolete do I need per operator?

You need exactly 5 Ruby Bolete to promote each operator from level 60 to level 80. This is a fixed requirement that doesn’t change based on operator rarity or type.

What time do Ruby Bolete respawn?

Ruby Bolete respawns once per day at the server’s daily reset time. The exact time varies by region, so check your server’s reset schedule in the game settings.

Can I get Ruby Bolete before reaching Wuling Map?

No, Ruby Bolete only spawns in Jingyu Valley within the Wuling Map. You must complete Valley 4 in the main story to unlock this area.

Is there a faster way to get Ruby Bolete than daily farming?

The Growth Chamber cultivation method at OMV Dijiang provides passive Ruby Bolete generation, but it requires Cabin Level 3 and is generally slower than active farming.

Do Ruby Bolete locations change?

The two primary spawn points in Jingyu Valley are fixed and don’t change. However, future game updates might add new locations in other regions.

What happens if I miss a day of farming?

You only lose that day’s respawn (2 Ruby Bolete total). The spots don’t accumulate missed days, so consistent daily collection is important for optimal progression.

Can I trade Ruby Bolete with other players?

No, Ruby Bolete and other promotion materials are not tradable between players. Each account must farm their own supply.

Does exploration level affect Ruby Bolete respawn rate?

Exploration level doesn’t affect the respawn rate (always daily), but it can increase the maximum yield per spot, making each collection more valuable.

Are there events that give bonus Ruby Bolete?

Special events occasionally offer Ruby Bolete as rewards. Follow the official Twitter and Discord for announcements about such events.

Should I save Ruby Bolete or use them immediately?

Use Ruby Bolete immediately on your main team to progress faster. However, keep a small buffer (10-15) for new operators you might acquire.

Conclusion

Ruby Bolete stands as one of the most crucial materials for advancing in Arknights Endfield. By following this comprehensive guide, you’ll efficiently locate, farm, and utilize Ruby Bolete to push your operators to their full potential.

Remember these key points:

Unlock Wuling Map first (complete Valley 4)
Visit both Jingyu Valley spots immediately for 20 Ruby Bolete
Farm daily for consistent progression
Consider Growth Chamber cultivation for passive income
Prioritize your main team for promotion

With proper planning and consistent effort, you’ll overcome the level 60 barrier and continue your journey through Arknights Endfield.
