- "You expect the Arms Tournament to be exciting, and it is."
- —Man regarding the Lacuer Tournament of Arms.
The tournament is used to test warriors from around the world in a one on one contest, sometimes resulting in death (though this is hardly encouraged). Each contestant is forbidden to use their own weapons, items and armor, and instead must select a sponsor to supply these things for them for use in the matches.
It is not clear how many matches are set up, but it is speculated that it all depends on how many contestants there are. Between each match, contestants are granted permission to watch the other fights from the stadium seats.

The first match of the semi-final round took place between rookie Claude Kenni and the skilled fighter Jose Duran, though Claude managed to scratch by victoriously.
The second and final match of the Semi-Finals took place between Dias Flac and strong-armed swordsman, Grondo Rawlos. Dias easily continued onto the Find Round.

The Final Round spawned a tough fight between Claude and Dias, though ultimately the champion resulted in the skilled Dias Flac with Claude taking second place.
The tournament in the Star Ocean: The Second Story manga is similar to the game version, with Claude and Dias fighting in the final round, but with different battles and participants. Ashton also participated in the contest, managing to reach the quarterfinals.
