Complete Main Walkthrough

Spoilers: this page covers the full main progression currently available, through The Priest.

1. First Contact

Choose your first DATA

The adventure begins in Stackham with Sanzu.

Choose one Level 5 starter:

• DATA #720 — Fire;
• DATA #1655 — Water;
• DATA #1328 — Grass.

After choosing, leave Stackham to the north and start exploring.

Before pushing into dangerous territory: read Exploration — Signal, Crystals & Lifeforce. Signal strength controls field recovery and how punishing a faint can become.

Answer Sanzu's call

When you cross the northern exit area, Sanzu contacts you and asks you to collect a package from the Vendor farther north.

Collect the package

Continue to Javerdale and enter the shop. The Vendor gives you Sanzu's package and advances the quest.

Return to Sanzu

Go back to Stackham and speak to Sanzu again. This unlocks:

• the DataDex;
• 3 DataCards.

Sanzu then asks you to build a full Party of 6 DATA.

Fill your Party

Capture enough DATA to reach six active members, then return to Sanzu. He unlocks the Cloud, allowing you to store DATA beyond the six active slots.

First Contact is now complete. Claim its reward in the Quest Menu:

• 300 loz;
• Booster ×1.

Sanzu then sends you to find Denzy in Cburg.

2. Road to Cburg

Recommended route

From Javerdale, follow the northern progression path:

Javerdale → Javerdale North → Nullstone Crag → Doubleloop Lake / Nullstone Crag South area → Cburg.

A physical connection also exists from Javerdale East toward Cburg West, but early progression is designed to route you through the intended northern path first.

Reach Cburg

Entering the Cburg area completes Road to Cburg.

Claim:

• 500 loz;
• Booster ×2.

3. Find Denzy

Denzy is inside the Cburg tavern/gym interior.

Speak to him for the story. He tells you about the Cathedral and points toward the old Aqueduct route.

His most important clue is about time: to get past the guard, you will need to wait until night.

Claim the Find Denzy reward:

• 800 loz;
• Booster ×3;
• Giga ExpDB ×2.

4. Ready for Rustvale

Return to Nullstone Crag South. Reaching this map after speaking with Denzy advances the next milestone.

Guard Bismarck

Guard Bismarck blocks the Aqueduct entrance.

• Day: he refuses passage and pushes you back.
• Night: he falls asleep. Speak to him and choose the option to slip past.

You are sent into the Aqueduct.

The Quest Menu only displays the next “Through the Aqueduct” milestone from player Level 31 onward. Bismarck himself, however, is effectively gated by the day/night cycle rather than that level check.

Entering the Aqueduct completes Ready for Rustvale.

Claim:

• 1,000 loz;
• Booster ×5;
• Giga ExpDB ×5.

5. Through the Aqueduct

Cross the Aqueduct until you reach Rustvale.

Entering the Rustvale region completes this progression step.

Claim:

• 2,000 loz;
• Booster ×7;
• Giga ExpDB ×10.

The Aqueduct also contains another major destination: the entrance to the Cathedral.

6. Inside the Cathedral

There are two ways into the Cathedral.

2. Rustvale / front-door route: equip Beverage Master and speak to Sentinel Barok. While Beverage Master is equipped, Barok lets you through and sends you directly to cat_01.

Beverage Master is unlocked by claiming QST_002 — Secret Score. The Secret Score guide covers the full side quest.

See the Cartridge NFT guide for the holder-specific route and other Cartridge benefits.

Reaching either Cathedral route completes Inside the Cathedral.

Claim:

• 3,000 loz;
• Booster ×10;
• Giga ExpDB ×15.

For the full dungeon route, see Cathedral — Complete Solution.

7. Overcome the Trial

The Cathedral contains six protocols spread across several floors. Activate all six before attempting the final passage on the second floor.

The route then leads to the Nave, where a major battle against Sanzu takes place before the Core.

After winning, continue to the Core and challenge The Priest.

The first boss tier is Level 50. Higher tiers can become available on later Cathedral runs.

Defeating The Priest at least once completes Overcome the Trial.

The boss victory has its own drop, while the quest reward must be claimed separately from the Quest Menu:

• 5,000 loz;
• Tera ExpDB ×3;
• Cathedral Hunter skin.

After the victory, you return to Rustvale.

Main Quest Rewards

After the current main story

The Cathedral remains replayable and has its own progression through repeated boss victories. Its achievement chain reaches 50 wins and unlocks another skin, separate from the main-quest Cathedral Hunter reward.

See the Achievement Guide.
