Honkai: Star Rail's Eerie Building Blocks Guide - 2026 Puzzle Solutions and Rewards

In the ever-evolving world of Penacony within Honkai: Star Rail, a particular set of collectible items has continued to captivate players well into 2026: the Eerie Building Blocks. These mysterious items, once shrouded in uncertainty regarding their purpose, are now central to unlocking some of the game's most rewarding post-story content and enhancing a key character. Players who have ventured through the dreamscapes of Penacony know that these blocks are not merely trinkets; they are the key to a final, grand puzzle and a suite of valuable rewards, including crucial upgrades for the Harmony Trailblazer. But how does one navigate this system, and is the effort truly worth it in the current meta?

How to Acquire Eerie Building Blocks in 2026

The method for obtaining Eerie Building Blocks remains exclusive and unchanged. The only way to earn Eerie Building Blocks is by successfully completing Dream Ticker puzzles scattered throughout Penacony. This is a non-negotiable requirement. Each solved puzzle rewards the player not only with a block but also with standard exploration loot such as Stellar Jade and various upgrade materials. For players aiming to maximize their resources, tackling these puzzles is a must-do activity.

• Total Puzzles: There are precisely 36 Dream Ticker puzzles hidden across the various zones of Penacony.

• Map Identification: Players can easily spot them on their in-game map, as they are marked with a distinctive puzzle piece icon 🧩.

• Puzzle Mechanics: Upon interaction, players are presented with a grid-based pathfinding challenge. The goal is to manipulate colored blocks—yellow, orange, and blue—to create a clear path for the adorable mascot, Clockie, to reach the target silver and gold gears.

Mastering Dream Ticker Puzzle Solutions

While the core mechanics are straightforward, some puzzles, especially the later ones, demand strategic thinking. The process always involves guiding Clockie to the gears by rearranging the environment. However, the key detail for 2026 players is location. The final and most challenging set of five Dream Ticker puzzles is located exclusively on The Radiant Feldspar.

Accessing this area is gated behind story progression. Players must complete the Trailblaze Mission "All About Eve," which is part of the climactic "Farewell, Penacony" questline. A clear sign that you're on the right track is the unlocking of the Harmony version of the Trailblazer character. For those who need visual assistance, numerous updated video guides from content creators like ZaFrostPet are available, detailing step-by-step solutions for all puzzles, including the tricky final quintet on the starship.

The Ultimate Reward: Exchanging Your Blocks

So, you've collected all the Eerie Building Blocks—now what? Their true purpose is revealed in a multi-stage quest. All collected Eerie Building Blocks must be exchanged with the Boss Ticker NPC on The Radiant Feldspar. This character is not immediately accessible.

1. Prove Your Worth: First, you must locate and solve four specific Dream Ticker puzzles scattered around The Radiant Feldspar itself.

2. Unlock the Quest: Completing these four will trigger the follow-up quest, "Dreams and the Art of Clock Maintenance II."

3. The Final Confrontation: This quest directs you to The Tatalov area, where you'll meet the Boss Ticker alongside the four other Ticketers. Here, you will face the ultimate Dream Ticker puzzle.

4. The Grand Exchange: After conquering the final puzzle, speak to the Boss Ticker again. You can then exchange your hard-earned Eerie Building Blocks in sets of seven.

The complete reward list for turning in all 21 blocks includes:

Reward Item	Quantity	Primary Use
Grand Duke's Robe of Grace	1	Eidolon Material
Stellar Jade	30	Gacha Currency
Chock Credits	120	Statue Currency
Credit	300	In-Game Money

The Chock Credits can be used at the Clockie Statue in Penacony's Golden Hour. However, the crown jewel of the rewards is undoubtedly the Grand Duke's Robe of Grace. This item is exceptionally rare. Besides a few specific missions, this exchange is the only way to obtain additional Eidolon levels for the Harmony Trailblazer. In the 2026 game meta, where Break Effect teams remain highly potent, maximizing the Harmony Trailblazer's Eidolons is considered ideal for unlocking the character's full potential. Therefore, completing this entire puzzle chain is not just for completionists; it's a strategic move for players invested in optimizing this powerful free character.

In conclusion, the journey from a mysterious collectible to a powerful character upgrade epitomizes Honkai: Star Rail's design philosophy. The Eerie Building Blocks are more than just a checklist item; they are the thread that leads players through Penacony's most clever environmental puzzles and towards a reward that continues to hold significant value years after the region's release. For any Trailblazer yet to undertake this challenge, the question isn't if they should, but when they will set sail for The Radiant Feldspar and claim their prize.
