The Lost Ark passcode in Stellar Blade is commonly transcribed as 0ukaEr or Oukaer. The game’s clue, “Turn Xion, turn clockwise!”, tells you to order the six symbols you find at terminals around Xion clockwise. Since guide typography for the symbols varies, use the glyphs shown in your game if the typed code does not match what you see.

How to unlock the Lost Ark quest

Travel to the Great Desert, then return to Xion and speak with Mann in the Presence Chamber. This makes the Lost Ark side quest available. Follow the missing-person lead behind the empty shops in northeast Xion: examine the body and documents there to find the clue and locate the locked Ark entrance.

Where to find the six terminals

Each blue terminal provides one symbol for the Ark keypad. The terminals are spread across Xion; walkthroughs place them in these areas:

  • The northeast alley.
  • The stairs near Gwen’s Hair Salon.
  • The alley by the Bulletin Board.
  • The first street on the left when entering Xion.
  • The steps beside Sisters’ Junk.
  • The central plaza café.

What is the Lost Ark passcode?

The in-game document says, “Turn Xion, turn clockwise!” Arrange the six terminal symbols clockwise, following the clue and the map. Walkthroughs transcribe the resulting code as 0ukaEr or Oukaer; some render the glyphs as Greek-like characters such as θμκαεγ. These are text representations of the symbols, so match the actual keypad symbols revealed in your game rather than relying only on letter shapes.
