FFXV Gravity Well UpgradeThis upgrade to the Gravity Well requires you to have a hydraulic cylinder. If it’s already in your inventory, head over to Cid Sophiar’s location and hand him the item. It’s worth mentioning, however, that hydraulic cylinders are hard to come by. Even worse, it’s easy to assume that it’s a worthless piece of garbage that is only good for some petty gil. Either way, if you’re having problems with locating hydraulic cylinders, check out our Hydraulic Cylinder Locations guide.
Either way, once you’ve gotten hold of the hydraulic cylinder, make your way back to Cid Sophiar as soon as it’s convenient. Once there, unequip the Gravity Well in case you’re carrying it. Then, give both the weapon and the cylinder to Cid. He’ll start working on building your new weapon, but it might take him some time. To pass the time until it’s finished, you can roam about and finish up some side quests or hunting jobs. Check back in with Cid after a while and he’ll present you with your new and improved Gravity Well, with better stats and higher damage output. You’ll also get a small amount of EXP for completing the quest.
