Within the ethereal expanse of Penacony's Dreamscape, Trailblazers navigating the surreal landscapes of Honkai: Star Rail will inevitably encounter a series of intricate mechanical challenges known as Dream Ticker Puzzles. These cerebral conundrums, marked by distinct puzzle piece symbols on the map, serve as gateways to acquiring a unique currency: the enigmatic Eerie Building Blocks. As the game's narrative has expanded with the release of the "Farewell, Penacony" mission series, the significance and utility of these blocks have evolved, culminating in a rewarding endgame collection system that offers exclusive attire and valuable resources for dedicated players.

🧩 Acquiring Eerie Building Blocks: The Path of the Dream Ticker

The sole method for obtaining Eerie Building Blocks is through the successful completion of Dream Ticker Puzzles scattered throughout the Penacony Dreamscape. This dream realm exists separately from the reality-based areas like The Reverie hotel. As of 2026, a total of 36 of these puzzles are available for dedicated explorers to uncover. Each puzzle presents a pathfinding challenge centered around the adorable mascot, Clockie. The objective is to manipulate an assortment of colored building blocks—yellow, orange, blue, and others—to construct a viable pathway. This allows Clockie to navigate from his starting position, collect a silver gear, and ultimately reach a golden gear to finalize the puzzle.

Upon solving a puzzle, players are rewarded with one Eerie Building Block. These items are not stored with regular materials; instead, they can be found within the player's inventory under the Missions tab, highlighting their significance as quest-related collectibles.

🏛️ The First Exchange: Meeting the Dream Ticker Supervisor

After accumulating a handful of these mysterious blocks, players are naturally curious about their purpose. The initial utilization point is the Dream Ticker Supervisor, located on Floor 1 of The Reverie (Dreamscape). The most straightforward path to this NPC is to travel via the Monitoring Room Space Anchor and proceed north. Players will typically be guided here organically through gameplay progression.

The quest chain "Dreams and the Art of Clock Maintenance (I)" automatically initiates after a Trailblazer has repaired at least five Dream Ticker Puzzles. This quest involves receiving a message from the Supervisor, leading directly to their location for the first exchange. By interacting with the Supervisor and handing over an initial batch of 15 Eerie Building Blocks, players receive a Precious Treasure chest containing substantial rewards:

Reward Item Quantity/Piece
Watchmaker's Illusory Formal Suit 1 (Wearable Cosmetic)
Stellar Jade 30
Clock Credits 120
Credit 300

This exchange provides a clear incentive for pursuing these puzzles, offering both aesthetic customization and premium currencies.

⛵ The Final Chapter: Unlocking The Radiant Feldspar

The narrative and puzzle landscape expanded significantly with the introduction of the new Dreamscape location: The Radiant Feldspar. Access to this area is gated behind main story progression. Players must complete the Trailblaze Mission "All About Eve," which is part of the later "Farewell, Penacony" mission series. Reaching this point requires substantial investment in the Penacony storyline.

Within The Radiant Feldspar, four additional Dream Ticker Puzzles await. Successfully solving all four triggers the next phase of the collection questline.

🤵 The Ultimate Reward: Dreams and the Art of Clock Maintenance (II)

Completing the quartet of puzzles in The Radiant Feldspar prompts the arrival of the quest "Dreams and the Art of Clock Maintenance (II)" via an in-game message. This directive leads players to The Tatalov district, specifically to a room occupied by the Boss Ticker. A conversation with this character unlocks access to the final, 36th Dream Ticker Puzzle in the game.

Solving this ultimate challenge awards the last of the Eerie Building Blocks. Returning to the Boss Ticker with the complete set allows for the final exchange. The reward is another Precious Treasure Chest, this time containing even more prestigious loot:

  • 🏆 Grand Duke's Robe of Grace: An elegant and exclusive cosmetic outfit.

  • 💎 Stellar Jade x30: Essential currency for Warps and resource replenishment.

  • 🕰️ Clock Credits x120: Specialized currency for the Dreamscape's economy.

  • 💰 Credit x300: Standard in-game currency for purchases and upgrades.
