Prepare a Secret Key and choose the correct tomb before entering. Upper and Lower Secret Tomb are separate destinations offered by the same entrance NPC.
How to enter
- Visit the Ancient History Scholar in Hotan.
- Reach level 125 or higher and form a party. Each instance supports up to 8 players.
- Carry a Secret Key in your inventory; the gate checks and consumes the entry key.
- Select Lower Secret Tomb in the NPC’s teleport menu. Confirm your party is choosing the same destination.
Before you go
The Upper and Lower destinations share the level and key requirements. Choosing one does not place you inside the other.
Arrange your group and supplies before confirming entry.

Each equipment tier is a separate chance for one random item. The box reward is from the boss, not one batch for every player.

Encounters & rewards
Open a boss to see its reward pools. Quantities and chances are per drop entry; an equipment or stone pool selects a random item, not every item in that category. Guaranteed quantities for the same reward are added together on one line.
