The world of Endfield may not be true open world, but it's certainly expansive and full of places to explore. Some of the materials needed to upgrade your Operators are scattered about, and while often times you can guide yourself to the closest gathering point, you'll still want to plan ahead which locations are farmed at different times, given that these spawn points get refreshed at a pretty slow rates. Here is a full list of all the Rare Growth and Rare Ore locations across the Valley IV and what is available of Wuling.
All Endfield Mushroom Locations
It's your job as the Endministrator of Endfield industries to keep your Operators well fed... even if this diet contains mushrooms only. The category of fungi is used for raising the levels of your Operators. Depending on which levels they're used for, some are available in multiple spots, while others only have a single farming spot in the game as of now.
All Pink Bolete Locations
Pink Bolete Fungus is a material you will need to Promote all your Operators from level 20 to the next patch, or E1 them. It's available in the starter hub and certain side areas.




- The first Pink Bolete location is easily accessible north of the Originium Byproduct Processing Center teleport point in Valley IV Hub.
- The second Pink Bolete location is likewise easy to reach, southwest of the Hub Base Power Plant teleport point in Valley IV Hub.
- The third Pink Bolete location is also in the Valley IV Hub, but this section of the map isn't accessible to you until you've come across the side quest about the restoration of Logistics Platform. This will require you to advance the Main Story.

The fourth Pink Bolete location is found in Valley IV's Aburrey Quarry, though it could be tedious to reach. In order to access it at all for the first time, you need to complete the Aburrey Quarry questline and obtain the Repair Logic of the area.
It requires some platforming, but once you get there, you can make it more accessible by dropping a nearby rope all the way down to the starting point of the Quarry and reach it from the teleport in future visits.

The fifth Pink Bolete location is found in the Arsenal of the Valley Pass, and it's readily accessible as soon as you're through with the quest of the Valley Transfer and on your way to the Valley Fort. The map speaks for itself, and the gap is easy to jump over. You can access the nearby rope for simplifying future pickups.

The sixth Pink Bolete location is found in a side pocket of the Cliffside Trail on your way out of the Originium Science Park. You will need industrial grade explosives in your quickbar in order to clear the Aether contamination and access this area.

The seventh Pink Bolete location is found in the Originium Science Park, in an area called The Depression. It's easily accessible, though you'll have to fight the guardian Originium monster in order to be able to pick up the goods.
All Red Bolete Locations
The next tier of fungi to E2 your Operators is the Red Bolete, available at four different spots in total across the Originium Lodespring and Power Plateau. You will need the carryable explosives on you at all times while exploring these maps.





- The first Red Bolete location is found in the Logisitics Area of the Originium Lodespring, easily accessible from the Mines Cable Car Station Teleport point once you clear the corruption.
- In order to access the second Red Bolete location, you will need to obtain the Repair Logic tiles and complete several puzzles to open the road across the torn highway. A zipline could shorten this trip for you once you're successfully across.
- The third Red Bolete location of the Originium Lodespring is hidden just out of sight on the Mountain Passage. Look over the ledge to collect this rare growth.
- The fourth Red Bolete location on the Power Plateau is accessible from above. If you follow the ramp just around the corner of where you can first see them through the wall, you'll find access from above and a rope that can hoist you out of the hole once you pick them up.
All Ruby Bolete Locations



The next tier of Bolete mushrooms requires you to reach Wuling, and both locations there are found near the Ecological Research Station in Jingyu Valley. They are easily accessible from either the Ecological Research Station teleport point, or the one found just south of the Threadway.
All Bloodcap Locations

The single Bloodcap location currently available is the one on the Chenshan Way, north of Wuling City. It's readily accessible in an alcove just through the pillar gate and to the left.
All Cosmagaric Locations

The only Cosmagaric growth as of now can be found on top of the Sanku Ridge, south of Wuling city. It's easy to reach from the Guhou Marsh teleport point, just make sure to follow the approach a little bit from the west so that you can climb the ridge from the slope.
All Endfield Flower Locations
Rare Growths of flowers and plants are used to provide resources for leveling the Skills of your Operators, and each bracket of leveling them will require its appropriate tier of materials.
All Kalkodendra Locations
Kalkodendra is needed to level your Operators' skills from their base to level 3 in Arknights Endfield.







- Potentially the very first Rare Growth of anything you will run into in the game, this Kalkodendra location is just a short hike away from the Core AIC Area.
- The second Kalkodendra growth is also found nearby in the Valley IV Hub, right next to the Southern Meadows teleport point.
- The Rockhill Passage unlock also gives access to a Kalkodendra growth, available after you clear the Hub main quest.
- Fourth Kalkodendra collection spot awaits in a tiny cave in the west part of the Aburrey Quarry, but you will require the Quarry Repair Logic to be able to approach it. Instead of being on top of the rocks, it's hidden in the mid levels.
- The fifth Kalkodendra location is also found in the Aburrey Quarry, and the easiest way to it is from the starting Quarry teleport point. All you have to do is drop down a few obscured ledges.
- The Originium Science Park Kalkodendra location is locked away behind an (un)powered gate, and you will need to bring electricity to it in order to access the mini compound on a ledge near the Kohl Park. The gated area contains little of interest, but when you climb on top of some crates you can jump out and beyond to this Kalkodendra growth.
All Chrysodendra Locations
The tier 2 Chrysodendra is found in the Originium Lodespring and on the Power Plateau.





- The first Chrysodendra spot is found all the way down on the edge of a low area near the Meteorogical station in the Originium Lodespring.
- The second Chrysodendra spot is hidden in plain sight inside of Originium Lodespring, but requires you to repair and activate a mechanism for moving containers nearby, which will in turn require you to have the corresponding Repair Logic. The container hiding this entrance is already lifted halfway and you can see an unreachable Aurylene hiding right below it.
- The third Chrysodendra location is easily accessible, and found just under a road near the Planned Construction Area Sub-PAC.
All Vitrodendra Locations
Vitrodendra will allow you to level your Operators' skills through levels 7 to 9. Both growths are found in Wuling, as is the case with all tier 3 materials.



- The first Vitrodendra farming point is found near the spot where you make it out of the Stragglers Grove in Jingyu Valley. It's easier to access it walking from the Sky King Flats Sub-PAC.
- The second Vitrodendra spot is found in the Wuling City area, and it's very easily accessible via the Guhou Marsh teleport point.
All Blighted Jadeleaf Locations

The only currently available Blighted Jadeleaf location is found in the Tianjing Courtyard, in the Wuling City area. There is a teleport point in a little bit southward into the Courtyard for ease of access.
All False Aggela Locations

The False Aggela location in front of Wuling City is not in fact accessible from the west, as it stands on the ledge and there's no way to climb without a zipline. Instead, the teleport point in the Maintenance Zone provides the quickest access to it. Bear in mind you probably can't avoid fighting the Bonekrushers on your way up.
All Endfield Mineral Ore Locations
The Rare Ores are not to be confused with the regular ores you can mine with the automatic rigs. They are not, in fact, used on the Factory lines at all. You will have to collect them manually from their growth spots or grow them on OMV Dijiang. They are used for weapon tuning, and you won't be able to uncap your weapons' potentials without them.
All Kalkonyx Locations
Kalkonyx is the base tier material used to tune Operators' weapons from level 20 to 40.







- The first Kalkonyx location is also the easiest to access, you can simply walk up to it from the Originium Byproduct Processing Center teleport point in the Valley IV Hub anytime.
- The Woodland Fringes in the Valley IV Hub hide another Kalkonyx node, and though it can't be accessed directly from the north since the Bonekrusher have taken camp (permanently), it can be walked up to from the south side, from a slope in the small clearing filled with blue flowers. You can also secure a future access from below via a rope nearby.
- The third Kalkonyx location is not accessible right from the bat, and you will need to complete the Valley IV Hub main story in order to unlock the Rockhill Passage slope. Once you do, it's a short trek from the Passage teleport point. The node is hidden in the side of the mountain.
- The fourth Kalkonyx spot is unlocked in the Aburrey Quarry, and is very easily accessible a hop and a skip over the ledge from the Stockpile Area teleport point.
- The fifth Kalkonyx location is found in the Originium Science Park, all the way behind the main building of the Research Center, best accessed from the Mountain Slope teleport point.
- The sixth Kalkonyx collection location point is found inside the cave system of the Valley Pass, under the settlement. It is only accessible after you start a rescue quest featuring Arclight. The quest's progression will naturally take you to this node. Afterwards, it's accessed from the Refugee Camp sub-PAC.
All Auronyx Locations
The Rare Ore Auronyx is needed to tune your Operators' weapons from level 40 to level 60. These ores found in the Originium Lodespring and on the Power Plateau.

The first Auronyx location will require you to use craftable industrial explosives on the obstacle in order to reach the deeper corridors of the cave. The closest access point is the Mines Cable Car Station teleport point.

The second Auronyx location is accessed similarly to the first, though you should instead take the jump across the fence straight from the teleport point and jump across the abyss with the jump pad eastward. The ore growth is found inside of the cave a little bit more to the south. You will need to clear out two corruption cores in order to be able to take this path.

The only Auronyx node found on the Power Plateau can be confusing to find. You will need to take the torn highway access southward to the Bonekrusher Warcamp from the Plateau Trunkway teleport point and hug the wall to the right to find the underground entrance to the room containing this Rare Ore. Make sure to have industrial explosives on hand in order to be able to blow the obstacle out.
All Umbronyx Locations
Umbronyx is the tier 3 material needed to tune weapons from level 60 to level 80. It's found at a total of two locations for now, both of which are in Wuling.

The first Umbronyx location is easily accessible from the Jingyu Valley Treasure Grotto teleport point in Arknights Endfield.

The second one requires a bit of a hike the first time you visit, from the Sky King Flats all the way south towards the Zhailing Islet. Make sure to bring 20 Ferrium bottles with fluid in order to be able to repair the bridge and access the islet section of the map.
If you're lucky and this connection is available in your world, you might be able to zipline straight from the Straggler's Grove teleport point. We still recommend making this connection yourself if it doesn't load in from multiplayer.
All Igneosite Locations

The only Igneosite location is easily accessible from the Guhou Marsh teleport point. In order to access it from the Field Logistics Depot teleport, you will have to clear out the Aether corruption in the narrow passage first. Watch out for slugs!
All Wulingstone Locations

The Wulingstone location is a tricky one, it looks like it can be accessed from the Chenshan Way but that's not actually the case. Instead, head to the Wuling AIC area and look southwest towards the cliffs; a rope is already set up for you to use and this is the only way to access Wulingstone for the first time. If you wish, you can set up ziplines for future visits, though the AIC teleport is quite convenient itself..
FAQ
A: No, none of these materials are used in the Factory and are only used to upgrade your Operators, their weapons and their skills.
A: No, the AIC gameplay is not connected to any of these materials.
A: If you want a higher output of rare growths and ores, you best employ your Growth Chamber on the OMV Dijiang. Make sure you have at least some of these materials at hand so that you can make the seed out of which to cultivate them in multiple copies!
