The Laconium Sword is a gimmick in the Quest which you can access to pick up. There will only be one Laconium Sword to start off, but four more will appear at the final phase. After putting down the Laconium Sword, it'll take about 10seconds until it reappears.
Certain areas will occasionally glow blue on the Dragon. Equipping the Laconium sword, will grant access to the Buster Divide PA. Unleashing this attack, fully charged, will break open a weakpoint on the glowing areas.
