How to Farm Necramech Repair in Warframe – Deimos Jugulus Rex Guide

Many unique Necramech mods, like Necramech Rage, from Orphix Venom are now available to farm in Warframe. If you know where and when to look.

The Necramech Repair Warframe mod is a useful tool when you’re out and about in your big stompy robot. Sadly, it’s also tricky to uncover. Necramech Repair, Necramech Rage, Necramech Augur, and several other useful mech mods were once only available as part of the Operation: Orphix Venom event. As such supplies are limited and Platinum prices tend toward the high side. Thankfully, alongside the Sisters of Parvos update, there’s a new way to farm Necramech Repair and its cousins: the Deimos Jugulus Rex.

I put the emphasis on Necramech Repair here because, of all the Orphix Venom mods, you cannot simply transmute it. That’s where you combine four random mods together to roll them into a new one — including the very useful Necramech Augur and the like. Necramech Repair is also damned useful. Whereas the Bonewidow Necramech can heal itself with abilities, this is the only guaranteed way to heal a Voidrig without external aid.

Oh, sure. Protea can generate health orbs. That makes her a great support ‘frame alongside Wisp during missions like the Profit-Taker boss fight and other content. But what do you do when that’s not an option? What do you do when you’re playing Orphix Railjack missions? Popping into a Warframe is rarely possible during that very lucrative activity (which is great for farming Arcanes). So you need something more self-sufficient.

Necramech Repair does exactly what it says on the tin: it heals your Necramech. Specifically, it repairs the robot’s health once every 15 seconds when those red hit points drop below 20 percent. That’s not much, but it’s a useful buffer. Particularly when you combine it with Necramech Rage. That mod produces energy for all health damage you take. The Voidrig mostly relies on energy to stay alive — using its Storm Shroud ability to create a damaging buffer of hit points. Using both mods together effectively provides infinite health and energy for longer self-sustainability.

The best use case for this combo is during Orphix hunts. This survival variant tasks you with killing Sentient monster spawners under anti-Warframe fields. Within these bubbles, you can only use a Necramech and/or your Operator form to fight, putting a greater emphasis on vehicle maintenance.

Now the question is: How do you get these mods? The good news is that Rage and Repair are found in the same place. The bad news is that they’re quite a pain to farm. The once Orphix Venom exclusive Necramech mods only drop from the Deimos Jugulus Rex. You can probably guess that this beast is found on Deimos, the Infested open world. Though it only appears in one specific area during one specific mission type… at one specific time of day. Yeah. It’s a lot of restrictions.

If you already have a Necramech, you might already know about Isolation Vault bounties. These special missions from Mother — the head of the Entrati family — take you beneath the surface of Deimos to fight rogue Necramechs and open secret caches. Isolation Vaults are also split into three tiers. Tier 1 vaults are marked by a three-star difficulty rating. They’re also the first step in unlocking your own Necramech with the Necraloid syndicate. This is where you want to start.

To begin farming, start a Tier 1 Isolation Vault bounty. Then just follow the objectives: collect residue marked on the map, defend the generator, throw bait at the “monster door,” and kill Infested. After which you’ll finally enter the vault. This is the part where you usually kill a hostile Necramech. And you should still do exactly that! The next part can be taxing enough without worrying about the evil robot. Once it’s dead, though, you’re looking for a specific part of the vault.

This monster mouth, or “Sarlacc pit,” is technically referred to as the Cenote Tile. It’s a huge, round funnel of meat leading down into the floor with an Infested mass hanging over it — ending in a stalactite of gristle and Orokin technology. It’s pretty hard to miss… if it spawns. The Cenote room is called a “tile” because it’s one of several landmarks that can occur in the procedurally generated level design of Warframe. Several other puzzle rooms can spawn instead. You just need to be patient. Very patient.

However, after testing different tiers of Isolation Vault dozens of times over multiple days, the pit puzzle does not seem entirely random. Instead it spawns according to the “day/night cycle” of Deimos: Fass and Vome. In much the same way Eidolons only appear on Earth at night, the Cenote room cycles along with the time of day. There’s the orange, glowing “sun” worm of the area that lasts for 100 minutes each cycle. He’s eventually replaced by the blue worm, Vome, for 50 minutes. If the wannabe Sarlacc appears during one of these cycles, it appears to do so for the rest of that remaining time period. After which the rooms may randomly cycle again. You just need to check the timer on your map or inside your Orbiter starship.

The real test of endurance isn’t even waiting. It’s running the Cenote puzzle over and over again. Sadly, leaving and reentering the vault (e.g. if you start an Arcana Bounty) does not reset the monster pit. You must return to the Necralisk to get a new Isolation Vault bounty from Mother. Then redo the entire bait, door, and Necramech process. Every. Single. Time. It’s annoying, but there are some ways to speed things up.

I specified the Tier 1 bounties earlier for a reason. These are the fastest way to farm Necramech Repair and hunt the Jugulus Rex. Since you can skip the rewarding (but laborious) Necraloid escort mission at the end of every vault, the biggest obstacles are waiting for timers and killing Necramechs at the start. Tier 1 bounties have weaker enemies overall and just one Necramech apiece. That shaves precious seconds off the opening tedium between attempts.

Finally we have the puzzle and the mini-boss themselves. Neither is particularly complex. Though they can get a little hairy for newcomers. Just shoot the Orokin gunk on the stalactite to start. A tanky Warframe with crowd control — such as Nidus, Inaros, or Rhino — will be a big help here. The reason being that the pit will counter by spawning explosive, toxic canisters into the room around you. These explode after a short delay and inflict the Toxin status effect if you’re too close when they blow.

You need to get close, however, in order to pick up the makeshift grenades. Lob one back into the enormous mouth pit (just like the bait grenade used to open the Infested vault doors).You’ll know you succeeded when the pit roars and the stalactite develops glowing boils (marked with red objective icons). Shoot these to drop some debris into the pit. The canisters will respawn and you can repeat the process two more times. After three cycles a huge, golden gear will careen into the pit and open the hole at its bottom.

That’s your cue to jump. Head into the hole and you’ll find a small arena with a unique monster inside: the Deimos Jugulus Rex. This is just a less aggressive version of the Jugulus you can fight on the surface of Deimos. It doesn’t do the underground spike attack or burrow away. Instead, it has tremendously fast health regeneration. But that’s not a problem! Just shoot out the yellow “eyes” along its narrow neck to halt the healing.

Once the creature finally falls it has a roughly 75 percent chance of dropping a unique Necramech mod. It also has a 25 percent chance of dropping a truly useless amount of Endo, which I personally find very funny. Or incredibly frustrating. Depends on the day.

Necramech Repair has only a 4.42 percent drop chance. Odds are you’ll need to hunt the creature multiple times. But that’s a lot less frustrating once you know the spawn conditions during Fass and Vome!

Now let’s close out on a few more general notes and tips:

  • Falling into the mouth before finishing the puzzle will “reset” you like any bottomless pit
  • Doing so will remove any equipped canister; you’ll need to pick one up again
  • The toxic canisters are denoted with yellow objective markers
  • The yellow markers only appear onscreen when you’re close, but appear on your mini-map at much greater distances
  • Joining public groups sometimes spares you from the first one or two steps of each vault
  • Necramech Repair commands a high Platinum prices among traders since it’s untransmutable and fairly rare
  • Vaults typically include just two “Orokin rooms” to check, surrounded by various Infested corridors

That should be all you need to know to get hunting! Best of luck with the potential arduous process, Tenno.
