Disclaimer:
This Guide is for those who intend to use [Cyte-09] as their main Warframe. All weapons and Companions are listed below for the optimal synergies, requiring a total of 25 formats.

Archon Shards:
2 Violet Taoforged: Primary Electricity
2 Crimson Taoforged: Ability Strength
1 Amber Taoforged: Starting Energy
(Who needs armor strip if you one-shot them anyway? Toaforged is not necessary, but gives bigger numbers. Additionally, one Violet shard can be switched for Crimson, yielding similar results with slightly lower damage numbers.)

Arcanes:

• Molt Augmented
  At full stacks, you will reach 500M damage red crits
• Arcane Crepuscular
  Gives you that extra big number dopamine while invisible.

Play Style:

• In this build, the primary goal is to deal massive amounts of damage while remaining invisible throughout the entire mission, regardless of the mission type.
• Use the Maduri focus school for best results, Zenurik also works.
• The Amber shard will provide you with enough starting energy to cast Evade. Then Neutralize and start clicking heads.
• As you use Energy [Dethcube] and [Verglas], they will begin to freeze all nearby enemies and drop energy orbs. This makes cyte 09 viable against infection, murmur, and techrot.
• You will also gain energy from the Violet shards, which will give electricity to the neutralizer and activate Archon Stretch. I have never seen my Cyte-09 drop below 400 energy.
• In the scarce case where you run out of energy, use the Vesper77 for easy headshots to maintain invisibility until the Neutralizer can be used again.
• The primary purpose of the Reconifex in this loadout is to support the Acolyte.
• The two [Neutralizer] builds are Energy and Electricity (Listed below). Use energy for the aforementioned shard configuration. Use Electricity if you are hesitant to commit Violet shards.

Possible replacements:
Umbral Intensify -> Precision Intensify

• This still deals massive damage and will one-shot everything, but overall, the damage is capped at 40 million in my testing.
