Rogo-Tumu-Her’s Haunt is a dungeon in the Devil’s Crypt that ranks at 72. The Open Robe is a dungeon in the Devil’s Crypt that ranks at 90. ..

The Ranks for Submersible Level are determined by the Submersible’s Part number. You’ll need good enough statistics to attempt these voyages if you have the Part number associated with your Submersible.

If you don’t have the ability to receive higher-grade rewards, you’ll be hunting for the Silver Dasher Minion for a long time. ..

The reason for this is that the submarine voyage is a long and drawn out process.

Depending on how far and in what Sector the Voyage is, the more time it can take. So it’s best to arm your Submarine with the best available parts to maximize rewards.

The other caveat is that these Sectors aren’t automatically unlocked. You’ll need to not only Level up, but unlock them sequentially by exploring lower Ranked Sectors.

The most time-consuming part of unlocking the sectors is generally up to chance. However, with a Higher Surveillance stat, progress can be made more quickly. ..

You’ll need to focus on specific Sectors in order to unlock the later Voyages. Knowing which ones to focus on will help you get there faster.

To unlock the Sectors and rewards for exploring them, you’ll need to complete the following tasks:

  1. Complete the main story mission “The Lost Tribe” in order to access the Sector 1-4 area.
  2. Complete the side mission “The Search” in order to access the Sector 5-8 area.
  3. Complete the main story mission “The Fractured Empire” in order to access the Sector 9-11 area.
  4. Complete the side mission “The Siege” in order to access the Sector 12-14 area.
