One of the high-level endgame dungeons to visit in "Final Fantasy XV" is the Crestholm Channels. To enter this dungeon without getting killed right away, party members must be at level 55.

When exploring the dungeon thoroughly with minimal problems, take note that the dungeon entrance is near Insomnia, which was at the start of the video game, according to Euro GamerSome Imperial troops blocking the way, and a couple of MA Veles mechs will be dealt with and it could become a challenge for early level players, but for those who are at level 55, they can handle the opponents with ease.

Players will have to enter the gate and turn right, go through a small opening in the fence. They can then head down a short flight of steps, and climb the long ladder to go down further to enter the mysterious dungeon.

The corridor along the south area is where players will have to go next, and up on the raised platform, which is on the left part. Interact with the electrical panel, which needs one of the four that they need to locate, here and then continue to the end of the corridor. Upon approaching the next area, expect attacks from some Bussemands, which can be taken out by broadswords, mechanisms and fire attacks.

After meeting some Gelatins, more Bussemands, and a Yojimbo, which needs Javelins, Guns and Lightning, head up to the stairs, and go around the corner to find a few more Gelatins and another electrical panel. Turn the switch on and then go back to the corridor and follow it to the end to fight some grunts.

When the players go through the next level, they will fight more Gelatins and another Yojimbo. They can just go drop down the slope in the northeast corner or fight the enemies, it is up to them. The fall will be far and it will give them some damage, so they need to prepare for that.

At this point, players will have to fight a miniboss in this next room called the Nagarani, which uses sweeping melee attacks and will use the Toad spell to turn the characters into one, according to IGNThis miniboss can also petrify them, so they need to be careful about that. She can be taken out by swords, polearms, and lightning attacks.

After taking out the miniboss, head to the exit to the north, turn left, and then proceed to the upper walkway. Follow the pathway, go up to the stairs, and go to the next room to fight more Bussemands. After defeating them, climb down the ladder in the northeast part, go down the tunnel, go into the octagonal room again, and climb the ladder to head to another room.

Fight the Black Flan in the next room and then climb the ladder, head for the octagonal room again, and then up another ladder. Turn on the third panel, open the door, and head inside. This will lead back to the first floor, but in a different location.

Four narrower passages are on the northern side, which they need to head to the passage second from the right. Some lights will be next to the fence on the western side of the first room, which the final switch will be located to be turned on.

After turning on all four switches, head back to the first room and then go to a new exit in the northwest corner. Defeat Jormungand with Gladio's Tempest Link Strike as one of the best methods to trim down its HP. After defeating the boss, the dungeon is now complete.
