What You Need Before the Treasury Halls Treasure Run
The Treasury Halls hidden treasure is tied to its own Eris task. Unlock and enter Treasury Halls during normal progression, return to Tresna, and speak with Eris when she displays a quest marker. Accept the named Treasury Halls hidden treasure task before beginning the dedicated search. Current walkthroughs consistently treat the active quest as a prerequisite, so verify the journal rather than assuming that entering the Gallery alone makes every secret portal available.
Accept the Treasury Halls Quest From Eris
Check the full location name because the Gallery contains two different treasure quests. Exhibition Wing uses a miniboss room and leads to Heartbeat Hunter; Treasury Halls uses a merchant event and leads to Blo-Blitz. If the journal names Exhibition Wing, searching for Sliver will not complete that objective. If no Treasury task appears, confirm that you have entered Treasury Halls, return to town, and speak with Eris again after the relevant progression.
Expect a Random Event Search
The entrance does not occupy a permanent treasure node. It appears inside one specific event room, and event rooms are represented by question marks on the route map. You are therefore looking for the correct event rather than following a fixed sequence of map coordinates. A run can generate a different character at every reachable question mark, in which case another Treasury Halls attempt may be necessary.

How to Find Sliver's Treasury Halls Event Room
Choose branches with the greatest number of reachable question-mark nodes. Each question mark is another chance to generate the Sliver event, while a route made mostly of standard combat rooms reduces the number of attempts in that run. Reveal the nodes as you progress and adjust toward additional question marks when possible. If another character or event appears, complete or leave that room normally and continue searching rather than assuming the treasure is elsewhere inside it.
Prioritize Question-Mark Nodes
There is no guaranteed fixed node number for Sliver, so route flexibility matters more than rushing directly toward the exit. Favor a branch that preserves access to later event nodes and enough health to investigate them. If the map offers no more question marks or Sliver never appears, finish or abandon the run according to your needs and start another Treasury Halls attempt. The missing event is a reroll problem, not evidence of a second hidden staircase in a normal room.
Confirm That the NPC Is Sliver, Not Silver
The required room contains Sliver, the relic-quality merchant. Some third-party walkthroughs write the name as “Silver,” but that is a spelling mistake rather than another NPC or another version of the event. Speak with Sliver when the room loads, then inspect the space directly behind him. The concealed stairs, the merchant landmark, and the active Treasury task together identify the correct entrance room.

Where to Enter the Treasury Halls Hidden Portal
Look directly behind Sliver for a staircase leading downward. Descend instead of taking the room's normal exit, then follow the obscured lower walkway to the portal. The foreground partly conceals the floor and can make the route look inaccessible, but no key or breakable wall is required. Walk carefully, align Will with the visible edge of the path, and let the camera reveal the next safe section before dashing.
Take the Staircase Directly Behind Sliver
Use Sliver's position as the fixed landmark. Move behind the merchant platform, find the descending steps, and stay on the available lower path until it reaches the portal. If you instead leave through the event room's obvious exit, you have passed the treasure branch. Return only if the room layout still permits it; otherwise, remember the landmark and prioritize question marks again on the next run.
Do You Have to Buy an Offer From Sliver?
Current sources disagree on whether accepting or buying an offer is a technical trigger for the hidden path. The consistent instructions are to interact with Sliver and then take the stairs behind him. This guide does not claim that spending gold is mandatory without stronger confirmation. If the staircase is present, use it; if the room behaves differently, document the game version before treating a purchase as a universal requirement.

How to Complete the Branching Platform Challenge
The portal leads to a self-contained platform route with branches that can end in dead ends. There is no need to sprint. Move one platform at a time, inspect the next landing before committing to a jump, and backtrack when a branch stops. The reliable environmental clue is a desk or table with a book. A route that reaches that object is progressing toward the reward rather than ending at an empty branch.
Use the Desk-and-Book Route Clue
Treat the desk and book as a confirmation marker, not as an item that must be carried. When a branch ends without the landmark or onward platforms, return to the last split and try the alternative. Current route coverage agrees on this visual clue even when videos frame the platforms from different angles. Following the environment is more robust than memorizing left and right commands that can become confusing when the camera changes orientation.
Collect the Recipe Scroll at the End
Continue beyond the correct branch until you reach the final reward and interact with the recipe scroll. Entering the portal, reaching the desk, or opening an ordinary chest is not enough to unlock Blo-Blitz. After the pickup, return to Tresna and check the appropriate weapon or Gadget crafting list. The appearance of Blo-Blitz is the clearest confirmation that the treasure reward registered on the save.
05 · Guide
Treasury Halls Hidden Treasure Reward
The Treasury Halls reward is the Blo-Blitz recipe. Current guides describe Blo-Blitz as a dual-gun or dual-wield weapon. Collect the recipe scroll to unlock crafting, then return to Tresna to make the item; the quest does not automatically equip a finished weapon. Check the recipe name when comparing rewards: Heartbeat Hunter belongs to Exhibition Wing, while Blo-Blaster belongs to Zephyr Fields. Neither replaces the Blo-Blitz unlock from Sliver's Treasury Halls route.
Unlock the Blo-Blitz Dual-Gun Recipe
After collecting the scroll, look for Blo-Blitz in Tresna's crafting interface. Do not confuse it with Blo-Blaster, the separate gun recipe associated with Zephyr Fields, or with Heartbeat Hunter from Exhibition Wing. Similar “Blo” names make reward tables easy to misread. The stable pairing for this page is Treasury Halls and Blo-Blitz, reached through Sliver's event and the branching platform route.
Use the In-Game Crafting Cost
Only one currently located database gives a detailed first-craft material list for Blo-Blitz, so that cost is not sufficiently cross-verified for a definitive route guide. Balance and material requirements can also change between builds. Use the recipe displayed in your installed version after unlocking it instead of farming against an unconfirmed table. This uncertainty affects the crafting cost, not the verified treasure location or reward name.

Do Not Confuse Treasury Halls With Other Secrets
Treasury Halls is the in-game area name. Shortened names such as Treasure Halls or the Treasure Hall can be ambiguous, so check the route rather than relying on the title alone. The Gallery's Treasury Halls and Sliver's event identify the Blo-Blitz route. Kalina and Howling Harbor are different destinations with their own Eris tasks, so check the journal before using a route described only as hidden treasure.
Check the Landmarks When a Guide Says Treasure Halls
The hidden treasure in Treasury Halls in Moonlighter 2 is the portal behind Sliver. If a walkthrough shortens the area to Treasure Halls or the Treasure Hall, compare its landmarks with this page: a question-mark event, Sliver, descending stairs, and the desk-and-book platform clue. Those details distinguish the Treasury Halls' hidden treasure from other Gallery secrets even when the title or location name is abbreviated.
Exhibition Wing Is a Separate Gallery Treasure
Older walkthroughs titled A Hidden Treasure in the Gallery can describe Exhibition Wing rather than Treasury Halls. That route begins after V3NUS, uses the stairs to the left of the post-fight chests, and leads through moving lasers to Heartbeat Hunter. Those landmarks do not belong to the Treasury route. If they match your quest or current room, switch to the dedicated Exhibition guide rather than continuing to reroll question marks for Sliver.
Masa's Display Case Is Not This Treasure
Masa's visible glass display case belongs to the separate Thief Trophy quest. It is not Sliver's event room, does not lead to the branching platform portal, and does not complete Treasury Halls' Hidden Treasure. If you reach the display case while following this treasure task, return to the route map and continue choosing question-mark nodes until the event contains Sliver and the stairs behind him.

What to Do if the Treasury Halls Task Does Not Complete
Back in Tresna, check whether Blo-Blitz appears in the crafting interface. If it does, the reward pickup registered even if the task remains visible. Players report hidden treasure objectives that stay unchecked after their recipes unlock. Preserve the save, fully restart the game, and install the latest available hotfix before repeating the entire event search. Do not erase a working save solely to remove an unresolved journal line.
Separate a Missing Portal From a Stuck Quest Flag
If Sliver never appears, the issue may simply be random event generation; prioritize question marks on another run. If the Sliver room appears but the stairs or portal cannot be used, confirm that Eris's matching task is active. If you collected the scroll and Blo-Blitz appears, the route succeeded and the remaining problem is likely task tracking. Those three states require different responses, so check them before replaying.
Record the Platform and Game Version
Before reporting a persistent problem, note the platform, installed version, journal wording, whether Sliver spawned, whether the portal opened, and whether Blo-Blitz appears at the forge. Capture the quest and recipe screens if possible. These details let support distinguish event randomness, a missing quest prerequisite, and a completion-state defect without asking you to risk the save or guess at unverified workarounds.
Questions, answered
Moonlighter 2 Hidden Treasure FAQ
Where is the Treasury Halls hidden treasure in Moonlighter 2?
It is accessed from Sliver's question-mark event room. Take the staircase directly behind Sliver, follow the concealed lower walkway into the portal, and complete the branching platform route.
Why is the Treasury Halls treasure portal missing?
The matching Eris task may not be active, or the question-mark node may have generated a different event. Check the journal and keep choosing event nodes until Sliver appears.
Is the Treasury Halls merchant called Sliver or Silver?
The character is Sliver. “Silver” is a recurring spelling error in third-party guides, not a second merchant. Use Sliver and the staircase behind him as the route landmarks.
Do I have to buy an upgrade from Sliver?
Sources disagree on whether a purchase is a hard trigger. Interact with Sliver first, then use the staircase behind him. The event room and concealed staircase are the consistently verified location signals.
What is the Treasury Halls hidden treasure reward?
The reward is the Blo-Blitz dual-gun recipe. Follow the desk-and-book branch through the platform challenge and collect the recipe scroll at the end to unlock it.
Is Treasury Halls the same as Exhibition Wing?
No. Treasury Halls uses Sliver's random event and rewards Blo-Blitz. Exhibition Wing begins after V3NUS, uses a moving-laser challenge, and rewards Heartbeat Hunter.
