This section will detail the item that is needed in order to complete the Ultimate Weapon quest.
1) - For starters, players will need to search Liberl for the volume series: Gambler Jack throughout Liberl.
2) - Once you've obtained all 14 -- Defeat the boss at the entrance and make your way to the 3rd floor of the Grancel guild. Talk to Baral and he will give you the Zemuria Ore. I know what your thinking... no, don't trade this item just yet. As you can also get a duplicate item on board the Liber Ark.
3) - Once you gain access to the Residential section, head to the western most building. Use the CPU and click on accept package, this will give you a Data Crystal Z. Then backtrack to the building where you got a Resurrect Jelly. When prompted, click on Data Crystal, this will give you a second Data Crystal.
4) - Once done, return to the Arseille and go to the Orbal factory room. Talk to Professor Russell, this will in turn give you the choice of two ultimate weapons. There's no right or wrong choice.
Note: When passing through the damaged Grancel castle town, be absolutely sure that you've obtained all 14. As when you pass through and defeat the enemy at the entrance and haven't obtained most of the Gambler Jack books -- the books up to this point will be unattainable.
