How to kill Adamantoise fast in FFXV

UPDATE: There’s a really quick way to kill the giant turtle, but it requires some preparation:

  1. Obviously, the higher your level, the better. Level 99 would be the best.
  2. Equip Noctis with the Zwill Crossblades (you can get them from Randolph).
  3. Equip accessories that increase your strength, like the Dark Matter Bracelet.
  4. Make sure you get a bunch of Power EX potions.
  5. Go to the camp spot near the boss and eat the Golden Tail Soup – it will guarantee critical hits.

Then comes the fight itself. It’s pretty straightforward. Here are some things to keep in mind:

  • Chug Power EX from time to time, to increase your attack.
  • Use the Armiger skill whenever you can.
  • Use Ignis’ Enhancement skill to increase the amount of damage you do.
  • Use Prompto’s Piercer skill to lower the turtle’s defence.
  • Go for the legs first.
  • Keep Noctis at full health at all times, so the Crossblades can do additional damage.
  • Once it slams its head down, attack it behind the tusks/horns.

ORIGINAL TEXT: This is one of the biggest creatures in the whole game of Final Fantasy XV, and you may have already passed it several times without noticing it. This turtle is already known for making an appearances in the Final Fantasy universe since FF 2, and in this case, Noctis and friends will have the chance to fight it after the journey is finished. Before the game was released, there was information that the fight can lead up to 72 hours, but you should be able to handle the fight in an hour or two.

How to kill Adamantoise in FFXV Adamantoise is a level 99 monster, and has the biggest amount of HP than any other creature in Eos. This Turtle is most vulnerable to Greatswords, so make sure you equip one before the fight. All the other weapons will come in handy as well, but the greatsword will give you damage boost when you attack the turtle.

The fight itself will be long and very repetitive, as this boss has over 5 million HP. Before the fight, make sure to cook and eat some of Ignis’ recipes that will boost your attack. The safest place where you should stay is at the turtle’s foot and deal damage in that area, while dodging the moves of the turtle from time to time. When you see that the eye opens up, try to make some hits there, as it will give you some more damage gain as the eye is the weakest point of the turtle. The moveset of the turtle is slow, but it can do some damage to Noctis, so don’t let your guard down because if you die, you will have to start the fight all over again.

In the end, it will give you over 40k exp points, but the satisfaction will be a greater reward. The citizens that went into hiding will come out, and you can go to the tipster and claim your reward for 50000 gil and an Adamantite Bangle.

        I started the quest without completing the game. used umbras ability to finish the cursed canvas quest and it started.

      Its not a real hunt. Talk to Cindy, she will have the quest starter. Then you have to talk to Dave at a location and then you will be free to start the fight.

        Actually… It is a real hunt. If you follow the quest, it tells you to run away at first. Once you flee, I do believe that you can certainly get back into combat with it if you so desire. But if you want to flee in order to prepare yourself for the combat ( going to camp to eat, or one of the restaurants for example ) you then have to accept the hunt from the man in Hammerhead within the restaurant in order to reestablish the battle with adamantoise.

          I apologize, that sounds confusing. Once you INITIALLY flee for the quest, I believe you can simply run right back to the giant turtle and fight it. However if you flee, going elsewhere first such as camp, etc., then you must begin the hunt via the clerk in Hammerhead. My apologies.

    you don’t need to beat the game. if you go back in time using Umbra right after you get to Altissa you will get a phone call from Cindy which will start you on the quest that unlocks the fight. Got it at lvl 54

  2. Ura

    After you beat Adamantoise you can go talk to Dave and get Oracle Ascension coins from peoples you talk in the Crow nest before you begin the Hunt.

    I just had spent a good 2 hours chipping away at this, I’m level 74, I was tiny bit away form killing it and was use the armigar chain, a cut scene put us all on his head and we shot down into its eye then I got blasted away, must have knocked me out of the circle coz it just ended the battle, I went towards it and he went back inside. So annoyed with that. It’s the easiest boss on the game made tedious with its massive health. Ah fuck it.. It can wait til I’m 99 now and hopefully does more damage.

    Just beat the Adamontoise – biggest strategy for me was using Gladio until I could use the chain Armigar, then warping the crap out of its head with the unlimited MP it gave me (unlock with AP). Took a little over an hour, but totally worth it!

  5. Johnny

    Was 3/4 done and 1 hour in… When the thing glitched its head flying me outside the battle area which auto-cancelled the fight… …
    Think I’m done with video games for awhile…
