Underworld (Another Dungeon)/Mechanics
Mechanics[edit]
The Underworld Another Dungeon costs 2x 
to enter and bears great similarity to Future Garulea Continent (Another Dungeon) in function.
Nazrik & Zero Point[edit]
You begin in Nazrik, which serves as a hub level devoid of encounters where you can trade for items. You are introduced to the Present Man and Lost Traveler.
The main resource is Sea-Drifts. You can collect them from the sparkle points in Zero Point (which you can freely travel to and from before committing to another location), or from beating Horrors.
Various merchants also offer their wares -- unique Grastas and Ores -- for either 180 Sea-Drifts or one Cat Dogu. Some of the more powerful Grastas or Ores go for twice that much. Every five runs will unlock a new merchant. You are required to complete each map once in order to unlock all the merchants.
If it's snowing in Nazrik, you have access to the Cat Shrine. Head east into Zero Point and use the glowing blue portal at its northern side to get a Cat Dogu. Snow has approximately 5% chance of appearing per run.
Initially, you can only access the Demon's Den from the lower-right corner of Zero Point. Purchase an Embedded Ladder from the Lost Traveler for 13 Sea-Drifts and give it to the Present Man, and on the next visit he will install the ladder to let you access the upper-left exit that leads to the Dimensional Cathedral.
After you've completed the Dimensional Cathedral, you can purchase a Genesis Dogu from the Lost Traveler for 13 Sea-Drifts. Use it at the portal on the upper floor of Nazrik to immediately open access to the Ark.
After you've completed the Ark area, the Lost Traveler starts selling Mural Fragments for 30 Sea-Drifts, and gives you one for free for your first time there. These are used in the basement of Nazrik for one-time access to the Mark of God's Tomb area.
Other Maps[edit]
Once you've committed to traveling to the other areas, you cannot turn back to Nazrik or Zero Point, and must finish the dungeon by beating the boss at the end. Each of the dungeon areas has 4 chests containing Grasta Pieces, and the boss chest has a low chance of yielding Jadeites or Chant Scripts.
Most of the consumables help remove barricades to open shortcuts, but there will always be one that leads to a dead end with a wooden chest. Opening the chest reveals the minimap for all future runs and reveals a new exclamation mark with a purple dot which requires a key to unlock new armor. The Present Man in Nazrik will offer to trade a Crooked-Tailed Cat Key for 2 Cat Dogus. Accessing the purple dots with this reusable key will get you armor that grants 10% Physical and Type resistance - the Oriental Bracelet is in Demon's Den, Oriental Necklace in Dimensional Cathedral, and Oriental Ring in the Ark.
The Mark of God's Tomb is a lot smaller and has no hidden items. However, its chests yield a lot more Grasta Pieces to compensate for its cost to entry, and the boss chest has a higher chance of yielding Jadeites or Chant Scripts. Note that Jadeites can drop from end rewards in this AD, so this map may not be as valuable to run.
Merchants in Nazrik[edit]
All ores from Future Garulea Continent (Another Dungeon) and the shops in Underworld can drop from End Rewards. The Grasta sold from the merchants on Nazrik 2nd Floor are unique and can only be purchased from the merchants.
