Hidden Treasures: Argus

Progress through the Argus campaign to unlock the Vindicaar Matrix Core, located in the basement of the Vindicaar. You must select an ability by clicking on the Matrix Core, then access it via the General tab in your spellbook — abilities like Light's Judgment and Lightforged Warframe do not appear as extra buttons automatically.

For treasures blocked by rocks that require Light's Judgment or Lightforged Warframe, you can bypass them by using one of these cushion toys in front of the rocks and sitting on it: Fuzzy Green Lounge Cushion, Pineapple Lounge Cushion, Safari Lounge Cushion, Zhevra Lounge Cushion, Cold Cushion, or Cushion of Time Travel — you will phase inside the rocks and click Exit Vehicle to enter the cave; use another cushion to exit. Alternatively, the Jump Attack ability from the "Blooming Rose" Contender's Costume can also push you through. Note that this bypass method does NOT work for treasures requiring Shroud of Arcane Echoes.
