1. Knockdown immunity Mods - Primed Sure Footed or Sure Footed + Fortitude
2. Unairu’s Poise - active for 40 seconds.
3. Frames that have their own ways of providing knockdown immunity like Revenant.
4. Infuse Titania’s Spellbind. :::

2. Surviving

Just in case you haven’t noticed yet, you deal more damage alive than when you’re dead. Builds have to both be tanky enough and be able to regain health.
Generally, tankiness is provided through a combination of using Adaptation, (Umbral) Vitality, (Umbral) Fiber, Arcane Guardian, Arcane Tanker, Shield Pads, the Ancient Healer Specter’s aura, and frame abilities.
Healing is primarily done by Magus Elevate, Magus Repair, Vazarin’s Protective Sling node, Elite On Call Crew with “heal 500 health on kill” or Vazarin’s Squad Regen node. Some builds may instead rely on frame abilities or weapon interactions to heal.

3. Covering All Elements

If you aren’t able to cover all elements, you have to cycle the ones you don’t have, waiting for the 5-second cycle cooldown each time. If you only bring 7 elements to the fight, you spend more time waiting for the cycle cooldown than it takes for some people to finish the entire fight.
Any good build will cover at least 12 elements across the primary/secondary/melee weapons and frame buffs. For builds where this is not an option, covering the missing elements with Voidrig’s Exalted Weapon Arquebex, using your operator to cover electric with your amp and virtuos surge, or using an on call crewmate is a good alternative.

Since the 1999 update, Volt's Shock ability and its corresponding Shock Trooper augment can be infused onto any frame to cover all elements except for toxin on a standard setup.

To maximize damage, it is preferred for a weapon’s single stat element (Heat, Cold, Electricity, Toxin) to match the weapon’s Primed Elemental Mod, like Primed Cryo Rounds for primary weapons or Primed Heated Charge for secondary weapons. This is not possible with all builds (and Rivens), so not every build abides by these rules.

4. Increasing Damage for All Elements

If we cover all elements but barely deal any damage with them, we won’t get very far. For that reason, all builds use frame buffs like Chroma’s Vex Armor or Mirage’s Eclipse, the latter of which can be infused onto any frame and is a better option even on frames that have their own damage buffs.

On weapons, we never spend more Mods than necessary to make a specific element. The remaining Mod space is used to buff all elements: it’s better to quickly take out all elements that a weapon covers than it is to instantly take out one element but slowly take out the others.

5. Clearing Pylons

The Pylons have shield bubbles around them that normally prevent all shots fired outside of the bubble from entering the bubble and destroying the Pylon, forcing you to travel to each Pylon and destroy them once inside.

There are four (known) weapons that can pierce shield bubbles. Ogris, Kuva Ogris, Zenith, Fluctus. Fluctus is not practical and will not be considered.

Ogris and Kuva Ogris require you to enter Archwing to get a line of sight to the Pylons and shoot them without spending time on getting close. Ogris variants allow you to preshoot Pylons, more on that later in Pogris

Zenith, using its Alt-fire, additionally pierces terrain because it has infinite punch through. This means you can stay on the ground and fire at the Pylon waypoints through terrain and shield bubbles alike. Unfortunately, Zenith is not readily obtainable. You can only get it when you log in on days 100/300/500/700.

6. Clearing the Armor Phase

During the Armor Phase, you can only damage Profit-Taker with Archguns. The game does not consider Arquebex (Voidrig's 4th ability) to be an Archgun. Players can choose to either have their frame wield the Archgun with the Archgun Deployer or have their Necramech wield it. Both options come with up-and downsides:

When wielding the Archgun on your frame, your buffs are applied to the Arch-gun, making it easy to deal a lot of damage. However, deploying the Arch-gun takes about 3 seconds, during which you can easily die to your surroundings or lose enough health to die or force you to heal again. Additionally, when you put away your Arch-gun, you can’t instantly get it back. Based on the gun’s max ammo and the ammo you use, you have to wait up to 5 minutes to use the Arch-gun again.
This means that the build has to optimize the damage per bullet and the Player has to minimize the ammo spent during each Armor Phase. Make sure you don’t waste ammo firing at already broken legs. This is why Ammo Chain may be part of some builds.
Alternatively, the Player can try to find and kill the Arch-gun-carrying corpus enemies. They will drop Arch-gun ammo restore that removes the cooldown from your Arch-gun.

When wielding the Arch-gun on your Necramech, your buffs aren’t applied to the Arch-gun, making it difficult to deal a lot of damage. However, Necramechs deploy instantly (as host) and only have to worry about magazine size, instead of max ammo.
