Fieldron Sample 2023 Guide


“This destroyed Fieldron could further research into super-heated containment fields”


Fieldron Sample is a resource that is needed to research a multitude of Corpus weapons as well as with the creation of Fieldron which is used to craft them.

Players may wonder what to do with Fieldron Samples and can figure later out that the blueprint for Fieldron may be purchased at the dojo in the Tenno Research Lab.

In the argument of Fieldron vs Fieldron Sample, Fieldron may be farmed from invasions and other events, while Fieldron Samples may be farmed in order to craft Fieldron.

Obtaining both Fieldron from invasions and Fieldron Samples from missions to craft even more Fieldron is ideal to have a good stock later on for blueprints that you may acquire.

In order to create Fieldron, players will need 10 Fieldron Sample and the blueprint for each crafting of the resource.

Where to farm Fieldron Sample? 

Fieldron Sample is farmable on Venus, Mars, Europa, Neptune and Pluto but most players will farm this resource on either Mars, Venus or Neptune.

Mars and Neptune are the best places to farm Fieldron Sample, whereas Mars is good for early Fieldron Sample farming and Neptune is the best location for late game Fieldron Sample farming.

Endless missions are suggested as you will require a lot of enemies due to the slightly low Fieldron Sample drop rate since more enemies means a better chance to get the drops.

Kelashin (Neptune)

Kelashin (Neptune)

Though not amongst the first of the resources, Fieldron Samples remain to have a good chance of dropping on Neptune, especially the Kelashin Dark Sector Survival.

With the 30% resource drop rate boost from the dark sector mission, you are guaranteed to get a good amount of Fieldron Samples when farming here.

Players will have a good advantage over the infested as they are short on range, weak against multiple damage types such as heat, slash and gas.

It is ideal to bring a Warframe that can force loot from the enemies such as Nekros for wandering and a Hydroid for camping, while a combination of both will do very well, especially with a squad.

Wahiba (Mars)

Wahiba (Mars)

Wahiba is practically a good place to get Fieldron Sample early game, since Mars is accessible early on as players start out in the game.

Since this is also a dark sector mission, there is an increase in drop rate but only by 20% unlike with Kelashin on Neptune.

This is a mission for those who can’t handle the high-level enemies on Neptune and can be done instead for farming Fieldron Samples at lower levels.

The map has a good number of spots where players may camp or do rounds when farming and a lot of loot spread out in containers for those who want to roam first.

Kadesh (Mars)

Kadesh (Mars)

Those who do not wish to do survival missions and would rather settle for a Dark Sector defense can set their eyes on Kadesh.

This mission can be handled by newer players as well as experienced ones for a good chance at Fieldron Sample drops as well as other rewards from being a defense mission.

The map is quite small, and players can easily keep track of the enemies and defend themselves, while stronger players may wipe the area easily with mid to high tier builds.

Kadesh may have an equal Dark Sector bonus to Wahiba, but it is certain that its survival counterpart can offer more due to the spawning of enemies.


  • It is no question that Fieldron Sample drops are low, and players are encouraged to use Warframes that can force loot out such as Nekros or Hydroid.
  • Fieldron can be obtained through invasions but having a good supply of Fieldron Samples can allow you to continuously craft it for later.
  • A Nekros is a good Warframe to have in your squad as they can last long during endless missions and their Desecrate ability has good range.
  • Fieldron may be purchased for 10 Platinum, meaning Fieldron Sample costs 1 Platinum each and it would be easier to just craft it instead of spending Platinum.


Fieldron Sample can be quite a pain to harvest if you do not have a farming Warframe and this is due to the low drop rate, but you are still guaranteed to get the drops from time to time.

A lot of research requires Fieldron Sample and several weapons require Fieldron, making it necessary to have an abundant supply if you want to craft Corpus weapons.

Farming Fieldron Samples in a group is pretty much the best way to go when farming this resource but in the event that you are solo, roaming with a Nekros or camping with Hydroid are your best bets.

    Fieldron Sample doesn’t exist on this planet. The guide is not valid.

      Since an update changed the resources in Jupiter causing Fieldron Samples to be replaced with Hexanon, Neptune and Mars have proven to be the best places to farm Fieldron Samples. We have replaced our old content with the new farming places.

      Fielderon samples DO NOT DROP from infested. DO NOT do the recommended mission.
      They drop from corpus.

        Apparently you are incorrect. The thing is, Neptune is controlled by the Corpus, and Fieldron Samples are part of the planet’s drop table. This means that the infested on the planet will drop Fieldron Samples. As of 4:25 PM 30/01/2020 we have entered the mission and can confirm that Fieldron Samples indeed do spawn in them. Perhaps bringing a Warframe that is suitable for farming or staying for more than one minute will help you get more than you are expecting to get but it is confirmed that Fieldron Samples do drop there. Next time make sure your claim is correct before saying such things. Thank you have a nice day. Do check out this link for more
