How to Beat Adamantoise – Preparation and Pertinent Information
The Adamantoise is a side boss in Final Fantasy XV which you’re required to beat if you want the Platinum Trophy or all 1,000 Gamerscore Points on offer. Defeating it will earn you the Tortoise Toppler Trophy/Achivement, but it’s no small task. This overgrown tortoise happens to be the size of a mountain, and you’ll have to beat the game first before you have a chance to fight it.
The Adamantoise is the target of a hunt titled “Lonely Rumblings in Longwythe” that you can obtain in Hammerhead by talking to Takka in the restaurant. In order to unlock that hunt, you must first beat the main story, then talk to Cindy in Hammerhead to begin the quest “Let Sleeping Mountains Lie,” which tasks you with investigating some earthquakes. When you head to the given location, you’ll awaken the Adamantoise, which unlocks the hunt.
Before setting out for the hunt, there’s a few things you should do to prepare. First off, you’re going to want to level up quite a bit. This is a level 99 boss with 5 Million HP, and it is absolutely monstrous, capable of dealing insane damage to you and your teammates. You don’t need to be level 99, though, thanks to the slow nature of this boss and its relatively simple attack pattern. Just try to be at least around level 70 to give yourself a better chance.
Another important piece of information is that there are no checkpoints during the fight, so if you die, you will have to start over from the very beginning. This may not sound like a big deal, but when you realize that this fight can easily take over an hour depending on your skill level, then it becomes a worry. On top of the restart issue, you can’t get auto-revived on easy. You must win the fight without dying.
There is a campfire nearby that you will definitely want to use in order to have Ignis cook a meal before battle. Pick food that increases your Critical Boost (such as Fishtsticks on Sticks) or something that increases your HP recovery rate (such as Triple Truffle Risotto). If you want a recipe that greatly increases both, max out Ignis’ cooking level to unlock the Golden Tail Soup recipe. It guarantees critical hits while also providing the best HP recovery you can get, making you virtually unstoppable for a while. If you have the AP for it, you may want to also invest in the Aftertaste, Lingering Aftertaste, and Persistent Aftertaste skills in Ascension under the the Exploration tree. They cost 18, 99, and 333 AP, respectively. These will greatly increase the amount of time that your stat bonuses from eating Ignis’ cooking will last.
For Noctis specifically, any stat boosts are welcome, but you really will want to save your AP for his Warp-Strike boosting abilities under the Combat tree. Warp Factor I and II are 24 and 52 AP, and will greatly increase the amount of damage you deal against the Adamantoise. If you have the points, go for Point-Blank Warp-Strike (333 AP) as well, since you’re going to be very close to the huge beast for pretty much the entire fight. When it comes to weapons, bring your best Greatsword, just make sure that it doesn’t have Holy, as the boss is immune to that.
Also, don’t forget to bring a ton of restoratives to keep your party in tip-top shape if things get rough. This is a long battle, so bring everything you can. You probably won’t need them early in the fight depending on what you have Ignis cook, but you’ll eventually have to rely on them when things get rough. Muscle Stimulant is very useful as well, as it provides extra damage, and you may want to bring some Magitek Boosters since they cancel MP costs, allowing you to Warp-Strike non-stop.
Once you’re all set up, it’s time to fight the Adamantoise.
