Daurell Caverns is an optional dungeon in south Duscae in Final Fantasy XV. The recommended level for the quest is 28, but it is based on the dungeon boss's level; some enemies are much tougher, but it's possible to run past some of them. It might still be wise to wait until past level 40.
The dungeon is found in the south of the Causcherry Plains in Duscae. The player can park up on the road directly south of the H in "Causcherry" (or north of the G in "Heights") and follow the path south. There is a fishing spot nearby; following the path southeast will find the entrance to the dungeon.
Clearing the dungeonEdit
The player will run into Necromancers that can outright kill Noctis from full HP, bypassing the "Danger" buffer. It is best to block their attacks. If they grab Noctis, the player should tap /, as failing to escape kills Noctis. They are weak to broadswords, shields, and ice, and resist lightning. They can confuse party members with clouds of smoke, or petrify them with their triangle beam ranged attack.
The player can take the left (southwest) fork and follow the path round. The player should climb down at the end to the lower level where a Ronin and couple Hecteyes spawn. Going through the narrow passageway will encounter poison on the floor that is mildly damaging to walk on.
At the junction there's a fishing spot straight ahead. The main path continues to the left. There is another battle against Necromancers past the junction. As the corridor widens further down more Nercomancers, Ronins, and Skeletons will attack.
At the next fork the right leads to a dead end. Ronins will spawn if the player explores it. At the end of the main path more Necromancers, Hecteyes, and Ronins will spawn and the player must fight them amid poison.
The player must next edge their way around the scaffolding to a ladder, descend and climb back up to open the shortcut, and continue to follow the scaffolding. After going past the narrow ledge, the player must head up the slope to find the Iron Giant boss. Ronins, Hecteyes, and Necromancers spawn alongside him. The player should aim to kill the Necromancers first. Killing the enemies completes the dungeon. Prompto's Starshell might come in handy, as the enemies are all daemons.
