Other Builds: Mech, Companion, Crewmate
Mech Setup
Mech build doesn’t matter as you shouldn’t spend much time in it. A basic health Mod should be enough if you have problems.
Corvas Build (non-Prime)

- For use on Necramech, this build can twoshot limbs if you fully charge it.
- Corvas has a lot of viable riven variety.
- Fire rate is low, so using Heavy Weapon may be faster.
- The build uses Primed Rubedo-Lined Barrel even if you’re using vex armor because Necramech doesn’t get Warframe buffs.
- Is affected by hitbox bug
Charged Velocitus Build

- For use on Necramech, this build will oneshot limbs if the weapon is fully charged.
- If you have damage bless, replace Venomous Clip with Shell Rush.
- Velocitus shots are either fully charged or not charged, so you need to fully charge it.
WARNING
Charged Velocitus often has hitbox problems, so you will likely have to go under Profit-Taker to hit the back legs.
Arquebex build (Used to clear Toxin Shield)

- This is one of the best ways to clear Toxin for frames that can’t do it themselves. Manually cycling Toxin works, but this saves a fair few seconds.
- Any frame with an Exalted Weapon won’t need this. They can put Toxin on the Exalted Weapon.
- Volt and Saryn don’t need this due to Volt shield and Toxic Lash, respectively.
- If the last element in a shield is Toxin, you can go straight from clearing the shield with Arquebex to breaking legs with Corvas.
- Arquebex doesn’t do any damage to Profit-Taker’s legs or body.
On-Call Crew
As the crewmate (more on this later) only needs to cover toxin (or electricity with Saryn), basically any weapon works as long as it:
- Has decent critical stats and good damage.
- Has a good enough fire rate.
- Ideally, has some sort of crowd control, i.e. chaining beams or explosions.
An example of a usable weapon is the Opticor Vandal, modded for toxin:

- Crewmates don't use rivens or conditional arcanes.
- An elite crewmate with the proper crit chance effect can increase your dps.
- Other usable weapons are found in On Call Strats
Companion Builds
Beast Build (Adarza Kavat)

- Essential mods are: Prosperous Retriever (credit doubling), Synth Fiber (passive reload), Tek Enhance (with Cat's Eye), Tenacious Bond, Reinforced Bond, Fetch, and Calculated Redirection (for Reinforced Bond). Others are flex.
- The given build is an Adarza Kavat build, which can't make use of Reinforced Bond without the use of Shield Restores, while other beasts can. If you don't care about the Adarza crit buff, you can use something like a Panzer Vulpaphyla instead.
- Make sure Cat's Eye is in the same mod slot as the build shown here (first slot) due to companions using Precepts.
- This build should work on all Beasts, with Cat's Eye replaced as appropriate.
- as for the Claw builds:
- Bite is required to make Tenacious Bond work
- Elusive Posture makes your Companion not run around, avoiding unecessary deaths on its part. May or may not be desirable because it stops it from killing enemies, too
Wyrm Prime

- If not using Verglas, Warrior/Assault Mode is flex.
- Enhanced Vitality is flex.
- Wyrm Prime is the only sentinel other than Nautilus Prime with enough base shields to rely on Reinforced Bond.
- Negate allows you to drop other forms of knockdown resistance with a bit of skill.
Weapons:
Vulklok Build

- Full build is far from necessary. You can just use Point Strike to proc Tenacious Bond and be done.
- The Vulklok’s high base critical chance allows it to easily hit the 50% critical chance required for Tenacious Bond.
- For Tenacious Bond, only Critical Delay or Point Strike matter.
Verglas Build

- The Verglas can do a decent job clearing adds when helped by Total Eclipse, however its damage against shields is paltry.
