Update - Update 34 /pet rework.

ALL companions are affected by Oberon's passive - https://warframe.fandom.com/wiki/[[Oberon]](/items/arsenal/43/oberon/)#Abilities

A build for the solo player. Great for every mission, every boss, every Eidolon, every Orb, every Lich and Sister, and every Archon. The mod body is solid, so auras/arcanes/shards can be changed.

Helminth - I prefer using "[Xata]'s Whisper", as it's an excellent utility power. Love the damage boost, strips away a Sentient's resistances for a time, and it's one of two powers ( Roar is the other ) that punch through the "Damage Attenuation" mechanic.

Aura - I would suggest using an aura forma, so you can switch out auras freely. Until then, " Corrosive Projection " will help as you level.

Mods - You can switch out the primed continuity and Primed Flow for their normal versions.

Arcanes - I use Arcane Guardian and Molt Augmented for the armor and strength boosts. Until you unlock the New War, Veilbreaker, and Zariman, you can use Nullifier or any arcane you choose in place of Molt Augmented .

Shards - I'm using 2 Amber Archon Shards for casting speed, and 3 Azure Archon Shards for armor.

BE THE HERO / HEROINE THAT WARFRAME NEEDS !
