Magnetic/Radiation/Corrosive/Cold Tenet Arca Plasmor. Highest general utility without micro management. LONG

This is a variation of the Magnetic/Radiation/Viral/Electricity Boomstick found here: https://overframe.gg/build/389428/tenet-arca-plasmor/magnetic-radiation-viral-electricity-boom-stick-tenet-arca-plasmor-general-use-steel-path-no-micro/.

It swaps Viral for Corrosive and Electricity for Cold, but otherwise remains the same. It's a good variation if you don't use [Saryn] (who procs Corrosive on everything) and are getting Viral from your pet, etc.

Do you want a shotgun that will blow up entire rooms of enemies in steel path and nuke single targets without worrying about enemy type?

Do you [Hate] swapping out mods before each mission and find you forget more than you remember?

This is the build for you.

A lot of morons recommend the kuva element toxin from a progenitor warframe like [Saryn] for [Tenet Arca Plasmor]. Let me assure you, these people are window licking knuckle draggers.

Yes, toxin allows you to get viral + radiation by just adding a cold mod, but then you are painted into a corner with [Galvanized Savvy]'s damage boost. Your choices are to add a second element mod that will just add more viral + radiation damage (and not a third element), or to add a different element mod that will combine with cold and remove viral, giving you toxin + something not viral + radiation.

You want MAGNETIC as your kuva element, not toxin. This gives you a base of radiation + magnetic with flexibility for your third and yes, FOURTH elements. Magnetic also wipes out enemy shields, making your third element more flexible if it focuses on health (like Viral).

The result is a triple-double + single element boom stick that's got diversified damage types, nukes shields, shreds health, and confuses enemies if they somehow survive and are not one-shot.

But how do I get a magnetic Tenet Arca Plasmor, you ask?

Do this:
1) equip Harrow/[Harrow Prime] or one of the other magnetic progenitor warframes
2) equip [Xoris], go into "solo" mode
3) Go to Hydra on Pluto, and enter the golden hand using a [Zenith] Granum Crown
4) Use the Xoris's throw + heavy attack to blow up specters
5) Kill the sister of parvos, but don't X her, look at her first - it will show you what weapon she has equipped
6) If it's Tenet Arca Plasmor, use X to subdue her, if not, leave and repeat the mission until you get Tenet Arca Plasmor - making sure to kill the annoying guy to get your token back.
7) After subduing her, go back to "public mode", do all the star chart missions, figure out her requiems, and vanquish her to get your shiny new magnetic [Tenet Arca Plasmor].

You want [Galvanized Savvy] over Hunter Munitions unless you are doing level cap runs. The 35% chance for slash procs is outclassed by the extra condition overload-like damage of [Galvanized Savvy]. Slash procs take too much time to kill enemies, and your goal is to blow up rooms fast, not DOT them while you sip coffee and write a doctoral thesis on navel gazing.

For arcanes, you want primary merciless level 5. This not only causes your damage to grow as you blow up rooms in steel path, it gives you a 30% reload speed boost, allowing you to [Shred] enemies without downtime.

This build absolutely shreds on steel path and has a fun factor of 11.
