The Best Endo Farms in Warframe
In Warframe, everyone needs Endo. Endo is a magical ball of energy that you use to level up mods. The gold-trimmed fodder for mods drop all over the place, but often not in huge amounts. You might pick up 5-80 endo in a mission, but farming like that will take you forever, especially with gold and Primed mods.
Luckily, we have some great ways to farm for Endo!
Kill Kela’s Cronies in Arena Mode
Arena Mode in Warframe is kinda weird. The maps are clearly made with the Conclave in mind. However, Arena Mode is actually set against NPCs. It’s a lot like the Index except for the fact you’re only there to kill. That’s it. You kill Grineer mini-bosses. First team to hit 25 kills wins, and it’s rarely the Grineer. The Grineer in these missions aren’t that tough, but they spread out a lot so you have to search for them. A Nidus or a Speed Nova can fix this though. As for their strength, I’ve done arena mode on a level 22 Nekros, using only a Vectis. It’s not that bad.
The downside here is that you need a very particular build to farm on Arena Modes. The most common features a Nidus and a bunch of Nekros-es, maybe a Hydroid or Khora as well. But the thing you really need is the Mod Drop Chance Booster, available from Sorties. The drops in Arena mode are actually Endo and are considered the same as mods internally, so you can get plenty of Endo.
Arbitrations
Funnily enough, Arbitrations are a very good way to get ammo. Many of Arbitration’s rewards are either Endo or Ayatan Sculptures, which can be turned into Endo with ease. It’s worth considering what game mode you are playing on though, as not all Arbitrations are equal. Infested are somewhat easy but a single Toxic Ancient can fuck you up. Grineer in comparison are harder to kill but also unlikely to proc anything nasty on you. Corpus are tricky, especially with a lot of Nullifiers around.
The big problem with Arbitrations though isn’t the difficulty or the inability to revive yourself. Oh no, not at all. To gain access to Arbitrations, you have to complete every single node on the star chart. A gargantuan task, even for older players.
If you don’t want to play Arbitrations, both Sorties and the Steel Path will help you get some extra Endo.
Railjack
The best farm for Endo is actually a very passive farm. When you play Railjack, you’re not thinking of endo. But all those pieces off scrap you pick up can be turned into tasty, tasty endo. It’s actually pretty surprising when you think about it. At the same time, you can also earn a lot of credits, so you can grind for multiple things at once. The majority of ship scrap is generally duplicates anyway, and you can scrap level 1 and 2 items with ease.
And don’t worry if you don’t have a Railjack. As long as you have Archwing, then you can have a go at Railjack. Don’t forget to at least try to help your captain though. Even if you don’t have a ship of your own, you should be making yourself useful, like firing the guns or using your Omni tool to fix holes.
Your Old, Unwanted Mods
Railjack is very good at a lot of things. But the highest supply of Endo might be in your orbiter, right now! Go look at your mods, then arrange them by Duplicates/Quantity. The last time I did this, I had 300 Vitality mods, about 50 Serration mods and, somehow, 1000 Redirection Mods. All those mods (aside from ones you are leveling up) can be safely converted into Endo. It may not be as long-term as actually farming Endo, but checking your mod collection occasionally will give you a nice boost.
All that being said, the Endo farm is incredibly drawn out. There are a lot of useful mods that need to be maxed out to get the most out of them. Mods like Hornet Strike, Vitality, Steel Fiber and Serration are must-have mods for a LOT of weapons and Warframes. The credit cost is pretty high as well.
Luckily, unless you have a desire to max out every single mod in Warframe, if you keep playing, you’ll get all the endo you need.
