Warframe Guide: How does one "Git gud?"

I've decided to do a new series on guides for certain games that have levels of meta-gaming so intricate, the Minotaur couldn't navigate them. And to begin, I'm starting with my favorite time-sink/abyss-that-makes-it-so-that-I-don't-have-a-life-anymore, Warframe!

To begin, the titular machines, the Warframes

Note: This guide requires at least some time in Warframe and at minimum a VERY basic understanding of the game's systems, such as movement, shooting, and melee attacks. If you are confused on any of these, you can check the wiki for further info. The most confused you will be is when you hear me refer to 'Bullet Jumping" and wall climbing and clinging. Also, there will be NO talk of any potential spoilers to the game's plot. You'll know what I mean if you get there. 

Firstly, context. Warframe has a system of customization that relies on the usage of items called mods. Your weapons, Warframes, and companions have a number of mod slots, limiting the number of mods you can gather. As you level the equipment by running missions, you gain mod capacity, which installing mods takes up. Certain mod slots have polarity, which halves a mod's capacity cost if the polarity matches. You can alter a mod slots polarity with Forma. There are also special "Aura" and "Exilus" and "Corrupted" mods, which I'll explain as we go on.

Strap yourselves in boys and girls, and get ready for Mr. Toads Wild Ride.

• Your warframe has three forms of health: Shields, Armor, and Health. 
• Shields, when you are damaged, get hit first. These can't soak too much damage, but regenerate after a 3 second interval. Your more fragile warframes will rely more on these than the tankier ones, as they shouldn't be taking too much damage too often, and have time to regen their shields. There are mods that increase this regen rate, but it's also important to know that your shields regenerate based on a percentage of their total. The more shields you have, the more each tick of recharging, well, recharges. Got that? Good. The next part should be easier. 
• Armor and Health work hand in hand. Health provides the actual number of points you have before you get turned into paste on the wall, whereas armor makes that health better, as so that you become dead less quickly. Effective health is difficult to calculate, but know that 300 armor will lead to you taking half damage. The exact calculation is on the wiki, so if you want, you can find it there. Tankier warframes rely on this stuff, so get it up quick.
• Next up, you need to know how your warframe's abilities. Certain warframes abilities will have certain purposes, such as making your warframe tankier, stunning or otherwise incapcitating foes, dealing raw damage, self buffing, and supporting squadmates. In order to make the most of these you need to understand four stats: Strength, Efficiency, Range, and Duration.
• Strength will increase the potency of your abilities. In essence, it will give bigger numbers. Those numbers include damage numbers, how powerful your buffs are, or how powerful you're debuffs are. Some abilities are not affected by Power Strength.
• Efficiency will make abilities cost less energy, and will affect every ability
• Range extends the range of your abilities. Some abilities, such as self buffs, are not affected by Range.
• Duration makes things last longer, and makes powers with constant energy drain drain less energy per second. Some abilities are not effected by Duration.
• The best way to up these four stats is Corrupted mods, which you can get from running vault runs, which requires a Orokin Derelict Key, which you get the blueprint of from the market. You will also need a Vault Key, of which there are four variants, and are obtainable from a clan Dojo. You can only equip one, and vaults require one of the variants, so you will need to work in a team, with each member having one variant. Also, each variant puts a debuff on you.
• Got all that?
• Good.
• Corrupted mods up one stat and reduce another. 
• Comparatively simple, no?
• That will form the base of your modding experience. There are two more details you need to know
• Aura mods can only be put in Aura mod slots. They provide team wide buffs
• Exilus mods give miscellaneous benefits, usually increasing mobility or giving you a radar or making you a better hacker. These can be put in any slot or an Exilus mod slot, which requires a Exilus adapter upgrade for your Warframe.

There. That's modding. But it isn't building. Building involves Forma, which, if you were paying attention earlier, alters mod polarity. In order to build your Warframe, you Forma appropriately to fit in the best mods for your build in the limited amount of mod capacity you have. 

And that's it. Now, if you'll excuse me, I'm going to go sleep until next year.
