Complete Guide to Finding Red Bolete in Arknights Endfield
Learn where to find Red Bolete in Arknights Endfield, including unlock requirements, farming locations, and how to use this material for character progression
To push your Operators past the level 40 threshold in Arknights: Endfield, you’ll need to track down Red Bolete. This rare fungi only becomes available once you venture into the more hazardous regions beyond the starting zones. If you’re ready to strengthen your squad and break through that mid-game level cap, understanding where this mushroom sprouts is essential for your progression.

Unlocking Access to Red Bolete
Before you can even think about collecting Red Bolete, there are two gates you need to pass through. First, you need to hit Authority Level 25. Second, you have to advance far enough in the main storyline to receive the “Down the Hill” mission. This quest takes you out of Originium Science Park and into a new region called Origin Lodespring, where Red Bolete actually grows.
The region itself sits northeast of Originium Science Park, past an area called Cliffside Trail. But here’s the thing—even if you wander over there early, the zone stays locked until that story mission opens it up. So hitting level 25 and following the main quest isn’t optional; it’s the only way forward.

Where to Find Red Bolete in Origin Lodespring
Once you’re inside Origin Lodespring, look for icons on your map that resemble a dome with bunny ears. These markers point to rare gathering spots. One set of icons will lead you to Red Bolete, while another batch shows Chrysodendra locations—another material you’ll need later for skill upgrades.
After you’ve picked up your first Red Bolete, you can make future farming runs easier by opening your inventory, selecting the item, and choosing “Rare Gathering Sites” from the tracking menu. This highlights all the spawn points on your map so you don’t have to wander around aimlessly.

Growing Your Own Supply
Here’s a smart move: once you collect Red Bolete in the field, you can extract seeds from it and plant them back at your base using the Dijiang Production system, specifically the Growth Chamber. This lets you farm the material without constantly running back to Origin Lodespring.
There’s a catch, though. The Growth Chamber only becomes available after you upgrade your Control Nexus, which happens through a quest called “Dijiang Upgrade and Maintenance I.” This mission unlocks at Authority Level 24, so if you’ve already hit 25 to access Origin Lodespring, you should be good to go. If you need help with other base expansions, our guide on expanding Core AIC area and increasing power output will walk you through those systems.

What Red Bolete Actually Does
Red Bolete serves one specific purpose: taking your level 40 Operators and promoting them to break through to level 60. This is the game’s second major promotion tier, sometimes called Promotion II or the second ascension phase. Before this, you used Pink Bolete to push characters from level 20 to 40.
When you promote an Operator to level 60, several important upgrades unlock:
- The level cap increases from 40 to 60, giving you room to make your characters significantly stronger
- Access to Outfitting II opens up, which means your Operators can equip purple-rarity gear instead of being stuck with lower-tier equipment
- Skill rank limits increase from 3 to 6, letting you further enhance abilities with materials like Chrysodendra
The promotion itself costs 25 Protodisks, 5 Red Bolete, and 6,500 T-Creds. Make sure you’ve stocked up on all three before attempting the upgrade. For insight into building specific characters after promotion, take a look at our guides for Last Rite builds and Laevatain builds.
Understanding character stats and elemental reactions becomes even more important once you start pushing into higher promotion tiers, so familiarize yourself with those systems as you progress.
Frequently Asked Questions
What Authority Level do I need to farm Red Bolete?
You need to reach Authority Level 25 and complete the main quest “Down the Hill” to unlock Origin Lodespring, where Red Bolete spawns naturally.
Can I grow Red Bolete at my base instead of farming it in the wild?
Yes, after collecting Red Bolete in Origin Lodespring, you can extract seeds and plant them in the Dijiang Production Growth Chamber. You’ll need to upgrade your Control Nexus first through the “Dijiang Upgrade and Maintenance I” quest, which unlocks at level 24.
How much Red Bolete do I need for a single character promotion?
Promoting an Operator from level 40 to 60 requires 5 Red Bolete, along with 25 Protodisks and 6,500 T-Creds. Plan accordingly if you’re upgrading multiple characters.
What’s the difference between Pink Bolete and Red Bolete?
Pink Bolete is used for the first promotion (level 20 to 40), while Red Bolete is needed for the second promotion (level 40 to 60). Red Bolete unlocks later in the game and comes from a different region.
