Groups, Kills, Prints Energy.
Credit to ninjase for making me aware how Manifold Bond works with mod order/ precept order. The game reads your mods First Line, left to right and then second line left to right, therefore to ensure [Manifold Bond] reduces [Cordon]'s cooldown, make sure to place [Cordon] above all other precepts. (previously I had [Primed Regen] above [Cordon] and I am unsure if that has an effect, but I am certain having Cordon be first in precept order works with Manifold Bond. I believe Primed Regen/[Regen] and [Vacuum] are Passive Precepts so the cooldown from [Manifold Bond] should ignore them, but to be safe I moved [Cordon] to first priority)

Primed Regen - We don't have room for defenses. good thing with PRegen and all the Bond's little buddy has a very short cooldown.
Primed Animal Instinct - I don't know how I used to play without this mod. So helpful to have a useful minimap. If you havent used it before, do yourself a favor and please try it, we always try to minmax numbers instead of Quality of Life adjustments, the game feels much better with a useful minimap, far better than your companion having a bit extra survivability!
Momentous Bond - Killing Eximus gives him more stasuses to spread around and increases his damage from Galvanized Aptitude on the Verglas
Manifold Bond - When he sucks, he squirts status all over the enemies. When you kill them, he sucks and squirts again. Say Goodbye to his refractory period.
Contagious Bond - Spread the love
Duplex Bond - Each of them are capable of killing 1-2 level 300 enemies a second. They literally just print energy orbs for your whole team. Funnily Enough This gets even stronger on your most energy hungry frames. As you are going through your cast rotations you will plop out [Nautilus] Clones and pretty much always have the OG who will Group and spread statuses, and 3 clones which will Prime Kill and Print Energy like nobody's business. It is so much Hilariously better than [Dethcube]'s signature [Energy Generator].
Do you happen to be doing Team buffs with the likes of Roar or Nourish subsumed? Well your little clone army benefits from that as well. Also as a 1000hr [Nekros] Main. I can attest that having other random minions for the enemies to shoot increases your survivability, your team's survivability and the objective's survivability where applicable.
Cordon - Free Grouping, and applies Viral Heat and Radiation Procs
Assault Mode - he shoots the verglas
Vacuum - he succ
Fired Up - You need to have pure Heat Damage on the verglas. not Blast, Not Radiation, Not Gas, just Heat. Free +100% Heat Damage for the weapon.
EDIT:
Update 34.0 (2023-10-18)
Fired Up has been both improved and simplified. Previously this would require that your Sentinel has been shooting continuously for some period of time, and then added a Heat damage multiplier. This has been changed so that the Sentinel gains a 5% bonus Heat damage on every weapon hit up to 100%. The bonus resets after 5 seconds if the Sentinel has not landed a hit during that time.
This Mod was difficult to understand and only worked if the Sentinel weapon already did some amount of Heat damage. The mechanics are now more intuitive and the bonus applies the same way adding a Mod would, so your Sentinel's weapon doesn't need to already do Heat damage to benefit.
EDIT 2:
People seem to be confused about how I mentioned to order the PRECEPTS (I- Polarity)
I have them like this because Overframe has the mod layout similar to a warframe, not the 2 rows of 5 like it is in game. As long as your PRECEPT order is [Cordon] first you should be good!
Also while I LOVED this little buddy, I feel like he got overshadowed by the Claws updates to pets. Nautilus will outdamage any other robot, but I have been using a Panzer Vulpaphyla for nearly a year now: https://overframe.gg/build/764579/
