Costlemark Tower Walkthrough

  • The door to this dungeon is only open from 7pm to 4am.
  • There is a radom maze that have a total of 4 entrances, only two of them are correct. Everytime players walk into a wrong route will end up in a punishment room with Red Giant plus other enemies. The number of Red Giant depends on how many times players have tried the maze.

Notes

  • Jabberwock is extremely vulnerable to lightning and greatswords. An extremely leath combination on him is a quitcast Thundaga spell and the Tunderbolt greatsword.

      To those who are glitching, I recommend saving before the block maze part. Exit the ruins and save, the beginning part will be empty at least. I screwed up on the maze and spent 6 hours looping it because I'm severely underleveled and tackling the dungeon with magitech suits, so everything is slow going for me. I'm still in chapter 3 lol. But I finished it, killed the jabberwocky, and collected the sword without any glitches thus far. Not sure if I found all the loot and I'm too drained to double-check but I don't recall getting the good chamberlain

        I think I have found the worse glitch possible...
        So after going through the maze 4 times and killing three red giants and a nagarina twice, I finally found the right way to do things and I got to the jabberwok. So after killing the damn dragon, I am looking around the arena to see if I can't find anything. I step to the elevator and I glitch out where I am falling and I can't land. After ten minutes of this, I give up and have to shut off the game. Now I am unsure if I even want to try and figure this dungeon out again..

          It wasn't glitched for me, the sword was there as soon as I defeated the jabberwock. I was lucky enough to find the right elevator at the 3d round, so only 2 red giants, and I didn't summon Ramuh, as I was lv 81. I did it in chapter 8, I had read the letter about the missing sword before (chapter 4), and I had the mission Costlemark tower activated, just in case that helps

            This dungeon has glitched so much on me, the elevators for the trials don't work and I've done the first one at least 9 times and none of the other trials will let me attempt them. I've followed so many play throughs and walk throughs and there's no solution for it. I've tried accessing different saves from different attempts of the story (e.g. New Game, New Game+ and my first save from the completed game) and it's the same on every file.
            They really need to fix this glitch.

              Here is one I have not seen yet. The damn nagarina that was with the three red giants....yes three....goes into underground water attack mode and never comes out. It just keeps attacking me with water from under the floor and i can do no damage to her at all. not even able to target her.

                I beat all 3 red giants in the third room, but nagarani is stuck underground doing the waterspout attack and will not come up. I've spent hours in this dungeon and it will be terrible if I have to lose all my progress.

                  I've encountered a worse glitch, either my teammates fall from the top of the elevator to the Jabberwock and either both or gladious or ignis rolls off, and even if you have them all on the elvator back up they can't leave the elevator

                    Whats the best tactic to kill the red giant you may ask... Pray to the six and hope that Ramuh graces you with his presence to oneshot that filthy daemon bastard :)

                      I beat the boss, accidently stepped on a warp pad that sent me to the beginning of the dungeon, beat it again down to the boss and this time there were 2 *****ing bosses

                        This tower needs a mandatory fix badly. Apparently there's a game break bug that people experience (myself included but I reload an older save, rotate your saves kids!) where after you defeat the boss, The Jabber, it will not activate the cutscene to pick up the Royal arm. Then there's the fact that people are unfortunately unable to go back down the elevator to the dungeon boss and are being locked out of the end game content. Ruining their hard earned saves. I hope someone can find a way to contact the developers to fix this situation.
