Normal Sanctuary Onslaught is good if you don’t have a rank 30 Warframe, but the overall exp and focus gains just aren’t quite there.

Every other room is just a random tile with the doors blocked off. (This also applies to the other options on this list, but in a less dramatic way, since kills are more easily shared.) You also can’t use gear items, meaning Necramechs and Archguns can’t be leveled up here either. The best way to maximize affinity gains is to have someone else do all the killing, while you clear up with your weapons. When you get kills with Warframe abilities, most of the affinity goes into your Warframe – great for Focus, bad for actual weapon leveling. There’s one downside though: if you’re getting the kills with Warframe abilities, then you won’t be leveling stuff up that fast. The entire point of the mode is to murder enemies as fast as possible, and that’s also the best way to level things up. High level enemies constantly spawning in, tiny rooms, no need to go anywhere… it’s an affinity heaven. The Slightly Less Obvious: Elite Sanctuary OnslaughtĮlite Sanctuary Onslaught is amazing when it comes to getting Affinity. Now though, all Corpus maps are absolutely HUGE! The only small Corpus map remaining is one of the Corpus Outpost maps on Venus (the one with the two buildings next to it), and you’ve only got a 1/3 chance of getting it. Both Io and the indoor Corpus Ship map used to be pretty damn good for getting Affinity, because they were also tiny maps. However, I used to be able to recommend Corpus maps. Speed and efficiency are the way to go, and these tiny Grineer maps have that in spades. This makes killing the Grineer quick and easy. The Grineer all spawn pretty damn close to the objective, and many Warframes can easily cover the whole map with their abilities. What makes these maps so good isn’t so much the fact that they have a lot of enemies.

So does Helene, with the small downside of the Grineer being a few levels lower. Between the faction, tiny map and the high enemy density, Hydron funnels affinity to you. There’s very little that can beat Hydron. The Obvious: Sedna’s Hydron and Saturn’s Helene Luckily, there are some hot spots where you can level things up more quickly. In fact, there’s over 800 items that can be leveled up! And after a while, you kinda get tired of leveling things up. And amps, Archwings, Necramechs… The list goes on. Not just the titular Warframes themselves, but guns and pets and swords as well. But most of this game is about leveling up new gear. Sure, there’s a small part of it that’s about skateboard grinding.
