• Alternative to the Kuva Hekk would be something like the Felarx with Devastating Attrition, make sure you do not mod for Crit if you use this weapon, and only use the base form not its Incarnon
• Use your closest equivalent mods if there is something you're missing, I might have galvanized savvy on in the video, but that mod doesn't contribute at all to damage done when you're going for a one shot, replace it with anything you think is helpful/QOL. Hell's Chamber is also slightly better than the galvanized equivalent at 0 stacks. Just make sure you have Radiation to deal with the boss.
• Beam weapons/Shotgun pistols shouldn't have any trouble replacing the Catchmoon, punch through weapons should work fine too
• Redeemer/Vastilok are also pretty useful for breaking Aerolyst Canisters but the Stropha is the easiest to use.
• Use your favourite invisibility warframe, they all work the same for avoiding enemies.

• Kuva Hekk for its alt fire and moded for radiation, and Silent Battery if using Ivara to presever invisiblity.
• Catchmoon or any weapon with infinite body punch through for dealing with Aerolysts. Containers must be destroyed to make them vulnerable. Suppress to keep Ivara invisble. Not modded for Radiation because enemies shooting at each other tend to get a little annoying when you're already trying to avoid everything.
• Heavy attack Stropha, an alternative to the Catchmoon.
• Madurai for Void Strike so that you can 1 shot an Archon before Damage Attenuation kicks in (DA resets if the Archon has not taken damage for a brief period of time, if you notice you are hitting low, stop attacking for a a bit 5-10s and you should be back to doing full damage.
• Companion does not matter.
• Ivara build mostly does not matter, Rolling Guard is convenient for surviving Heat/Electric DOT but is not mandatory. Energy, Efficiency and Duration are what you want to prioritize.

0:24 First Phase

• Get close to Boreal, swap to Operator and activate your operators first ability with 1 (Don't know console equivalents)
• Switch back to Ivara and use the Kuva Hekk's alt-fire to one shot this phase then travel to the marked objective

0:32 Deacons

• After making it to this point in the mission, two Deacons will be marked on the map. Kill the enemies tethered to them to make the Deacon Vulnerable, and bring back the dropped item to one of the Statues.

1:00 Repeat the previous steps for the second Deacon and then make your way to the boss after placing the second Veil into the other statue

1:19 Second Boss encounter

• This part of the recording might be a little disorientating, some weird bug where my Operator and Warframe are facing different directions when using Transference, but at least this part of the recording showcases abilities that the boss can use if you need to deal with them when you go through this mission.

• If you are fast enough you can 1 shot this boss in the same way as Phase 1 1:24 If Boreal makes a large Blue Orb, you must damage this with your Amp to make him vulnerable (Similar to how Void Angels work)

1:45 Aerolyst Invulnerability Ability

• Boreal Spawns Aerolysts which must be killed before he becomes vulnerable again
• Use either the Catchmoon or Strohpa to break the Canisters around the Aerolysts, and then you will be able to kill them. Use your Amp to reset their damage resistances if necessary.

2:55 Pyramid Invulnerability Ability

• Shoot the corners of the Pyramid that have a Orb on the corners. Amp isn't required, any weapon works for this

3:25 Killing the Archon

• Same as phase 1, change to operator and press 1 for Void Strike and then use the Kuva Hekk's alt-fire to damage the Archon
• If you don't 1 shot the Archon, shoot it again and judge if you want to chip away at it's Hp until it's dead or wait for Damage Attenuation to reset.
• Collect the Archon Shard from the Archon once it's dead and extract.
