Easy LASO Method and Mythic Progress Loop

Build a strong personal-modifier preset, complete one LASO mission, save and exit at the next level, then disable the preset and trigger a Pillar of Autumn checkpoint so progress registers. Repeat the loop for all 13 missions while the method remains unpatched.

Before you start

  • Unlock all Skulls so the LASO playlist appears.
  • This method relies on behavior described as a glitch and may stop working after a patch.
