Honkai: Star Rail - Penacony Grand Theater Full Exploration and Chest Guide (2026)

The Penacony Grand Theater, a location foreshadowed from the very inception of the Penacony storyline in Honkai: Star Rail, finally opened its grand curtains for exploration with the Version 2.2 update. This majestic venue served as the climactic stage for the region's narrative and, true to its significance, presents itself as a vast and intricate exploration zone. To achieve 100% exploration progress, Trailblazers must not only scour the main theater halls but also venture into its four distinct expansions, accessible through special portals. This guide provides a comprehensive, step-by-step walkthrough for locating every treasure chest and collectible within this sprawling performance palace.

The main theater area itself is a labyrinth of corridors, balconies, and hidden rooms, housing a significant number of treasures without requiring portal travel. Let's begin the hunt here. Teleporting to the bottom Space Anchor immediately reveals the first chest waiting on the lower edge of the platform. A short distance away, deep inside the room adjacent to this Anchor, lies the second chest. Progressing towards the theater's grand entrance, a chest is clearly visible in the right-side hallway. The room directly ahead from this point conceals another treasure, tucked away on its left side.

As you pass through the main entrance, be vigilant for the area's Warp Trotter, a valuable mobile treasure. Descending the grand staircase and taking the left path leads to a chest perched on a pedestal-like platform extending toward the stage. Continuing forward from this point, the path eventually opens up into a wider area where the next chest is nestled in the left corner. Nearby, a Lordly Trashcan sits regally on a counter. A small room directly ahead of this quirky NPC holds yet another chest. Exiting this secluded section via the opposite path reveals another treasure on the left.

The exploration then shifts to the theater's upper levels. On the top left side, an extended platform to the left of the main stage holds a chest. Returning to the Space Anchor near the main entrance and taking the right path this time, Trailblazers should enter a secluded room on the right to find the next prize. On the ascending stairs near this chest, the second Lordly Trashcan awaits conversation. Not far from here, on a counter in the main area, sits another standard chest.

A special set of three chests is locked behind a significant challenge. These can only be claimed after defeating the final Hanu's Adventure puzzle within the theater, which itself is only unlocked after completing every other Hanu's Adventure scattered across Penacony. Once this feat is accomplished, the rewards are substantial. Finally, leaving the last secluded area presents one final chest on an extended platform directly ahead, concluding the main theater's treasure haul.

The journey continues within the theater's narrative-driven expansions, referred to as Acts. The first act expansion is found by taking the left path from the main theater area. Immediately upon entering and descending the first set of stairs, the first chest is found. Following the linear path leads to a second chest in a small, secluded area to the left. This act introduces moving stage modules as a puzzle mechanic. The third chest requires manipulating the first module to cross a gap, then, in the next area, using a second module to create a bridge to the side before proceeding.

Moving the module after collecting the third chest and progressing forward reveals the fourth treasure on the path. Before heading further down, a detour down some stairs and another module manipulation yields the fifth chest. The final chest in Act I is found by moving a module back and reaching the very end of the expansion area. The puzzles here are straightforward but essential for completion.

Act II, accessible through its own portal, presents a different challenge. This area features numerous chests, but most are tied to Dream Jigsaw puzzles encountered during the main story quest. Crucially, while these puzzle chests remain marked on the map even after being collected, they do not contribute to the area's exploration percentage. For exploration progress, Trailblazers need only find the two main exploration chests. The first is located by taking the right fork when the path divides early on and following it to its conclusion. The second chest, mirroring Act I, is positioned at the absolute end of the expansion area.

The final act, Act III, is found on the right path from the theater's main entrance. It introduces the whimsical Bubble Bridges as a traversal mechanic. The first chest here is found by taking the right fork when the path splits and using a Bubble Bridge once. For the second, return to the main fork and take the left path this time, using the Bubble Bridge twice; the chest will be on the right side. A chest is visible from this location but requires moving a module in front of the second chest's spot and traversing more Bubble Bridges to reach it.

The fourth chest requires further puzzle-solving: you must operate the module from the right-side mechanism to create a path. The fifth and final chest of Act III, and thus the Penacony Grand Theater, is once again found at the terminus of the area. It's a fitting reward for navigating the theater's final challenges.

Beyond these marked exploration chests, the Penacony Grand Theater, like all of Penacony, hides additional treasures behind environmental puzzles such as Dream Tickers and Formidable Foe combat encounters. While these special chests do not count toward the 100% exploration progress metric, they are highly worthwhile, typically offering rewards superior to standard Basic Treasures, including valuable upgrade materials and Stellar Jades. Completing the full sweep of the Grand Theater is a rewarding endeavor, ensuring no stage prop, hidden balcony, or dreamy secret is left unexplored by the diligent Trailblazer.
