- Obtain the Aetherium HeartUse Julien's recipe path to obtain the Aetherium Heart, a large sword. The evidence does not establish a complete ingredient list, so this page does not invent one.
- Return to the glass prisonThe target is the trapped NPC's glass prison in Technology Area 2 / the Treasury Halls route. Use the landmark and the cell rather than a guessed room coordinate.
- Strike with the named weaponEquip the Aetherium Heart and attack the glass. Ordinary weapons are specifically reported as ineffective for this prison; no generic sword substitution is asserted.
- Check the release feedbackThe barrier visibly breaks and Masa is no longer trapped. The linked video describes Masa and the Combat Rod as the reward route.
