Boss Guide

The Duchess of Queensbury is an eldritch horror that serves as the boss of the Queensbury Crypt dungeon. As a being of cosmic terror, the Duchess embodies the dark, gothic themes of the crypt with a design that blends aristocratic elegance with grotesque, otherworldly horror.

The fight takes place within the deepest chambers of the crypt, where the Duchess commands the undead and unleashes eldritch attacks that fill the arena. This encounter tests the player's mastery of the burrow mechanic, as dodging her wide-area attacks requires precise underground movement and well-timed pop-up strikes.

The Duchess may be connected to the Duke, a timid character searching for his lost love. Whether the Duchess truly is the Duke's long lost companion or merely masquerading as such remains a dark mystery. (Source: minathehollower.wiki.gg)

A hidden boss found deep within the Queensbury Crypt. To access the Ancestor Chamber, you need 2 Plasma Vials to open the sealed door. Once inside, you must actively insult/provoke the character to initiate the boss fight -- the battle will not start on its own.

This encounter is considered relatively easy compared to other hidden bosses. The reward is the Fly Bait Trinket, which attracts flies and may have utility for exploration or combat setups.

Maxi is an ambush boss that triggers when you return to Ossex after completing the first dungeon in Queensbury Crypt. Enter the town from the right side to trigger the encounter.

Maxi's signature move is burrowing underground frequently. The recommended strategy is to use your own burrow ability to counter his -- when Maxi digs, burrow yourself to avoid damage and reposition for a counterattack. Matching his burrow timing is key to winning this fight.

Defeating Maxi rewards the Trinket Pouch, a highly useful item that expands your trinket equip slots, allowing you to equip multiple trinkets simultaneously. This makes Maxi a priority fight for players looking to maximize their build options.

Armand is a functional boss encountered at the Ossex blacksmith shop run by Legovich. The fight triggers when you attempt to purchase a second item from Legovich. Armand has extremely high damage reduction, making normal attacks nearly ineffective.

Exploit Strategy: Use your burrow ability to redirect lava onto Armand's position. Once he steps on the lava, his damage reduction is removed and he becomes vulnerable to normal attacks. This is the intended or at least most effective way to deal with his otherwise impenetrable defense.

Defeating Armand unlocks the blacksmith shop for normal operation, making this a functionally important boss fight rather than one that just grants a trinket.

New Info: The 163.com weapon guide confirms that Armand is the blacksmith who blocks purchases. The fight triggers on your second purchase attempt. His difficulty is described as "hidden boss level" — if you lose to him, it means your equipment and skills need more work. The blacksmith is named Legovich and his shop is in the red building in central Ossex.

Darkin is a randomly spawning boss near Ossex High Street. Two children named Ak and Dak will mention Darkin, providing the clue to his existence. He can appear in one of two possible locations: near the south outskirts (close to the sunbathing man) or in the western hills (before entering Backwater).

Darkin is unique in that you must defeat him twice to truly beat him. After the first victory, he will reappear and must be fought again. Only after the second defeat is he considered fully vanquished.

The reward for defeating Darkin is the Lace Glove. Due to the random spawn mechanic, you may need to leave and re-enter the area multiple times to encounter him.

New Info (June 5): The Darkin encounter is actually a pair of children named Ark and Duck who talk about a legendary creature called "Darkin." The actual Darkin boss has random spawn locations — it can appear in one of two places: near the sunbathing man in the South Suburb, or in the West Hill area before entering Backwaters. You must defeat it twice to fully defeat it. The reward is the Lace Glove trinket. Due to the random spawn mechanic, this boss can be time-consuming to find.

After defeating the Nox Beast in Nox's Bayou, a hidden escort event becomes available. From the shortcut, go downward, follow the rope down, and look for a room behind a waterfall on the left. Inside you'll find a frog in a barrel that needs to be escorted.

Escort Route: Guide the frog through obstacles and enemies back to the shortcut area. From there, head to the Backwater region (the large swamp area with moving platforms). Hit the frog northward to send it toward a band of musician frogs so it can reunite with the band.

Completing the frog escort rewards the Tutu Ballet trinket. This event also serves as the prerequisite for the Music Hall Shark Pirate series -- after reuniting the frog band, pay 100 Bones to send the band to Ossex, which unlocks the Music Hall boss encounters in the Bowery District.

New Info (June 5): After reuniting the frog with its band in Backwaters, you receive the Tutu Ballet trinket. Then talk to the frog again and pay 100 Bones to send the band to perform at Ossex. This payment is required to unlock the Music Hall boss chain in the Bowery District. If the frog gets lost during escort, it will reappear at the nearest shore.

After completing the Frog Escort Event and paying 100 Bones to send the frog band to Ossex, a series of boss encounters becomes available at the Music Hall in the Ossex Bowery District. These bosses are Shark Pirates who perform at the venue.

Entry Method: The Music Hall has a guard at the entrance. To bypass the guard, burrow under the customers' feet near the entrance to slip past. Once inside, speak with the Shark Pirate near the stage to initiate the boss encounters.

The exact number of individual boss fights in this series and their specific rewards are not yet fully confirmed. Current information suggests there are approximately 4 Shark Pirate bosses (filling the remaining slots of the 9 hidden bosses), but details on their names, attack patterns, and rewards remain incomplete pending further community documentation.

New Info (June 5): Based on the 163.com hidden boss guide, the Music Hall sequence involves entering the Bowery District Music Hall in Ossex, burrowing under the entrance customers to bypass the guard, and talking to a Shark Pirate near the stage. The exact number of boss encounters and their rewards remain unconfirmed — the original guide author noted they did not complete this sequence. This is considered one of the most information-gaps in the current guide.

New Info (June 10): Mock Moon has been added as Hidden Boss #6 with full details. The Music Hall Shark Pirate series is now Hidden Bosses #7-9. Total hidden boss count remains at 9 confirmed.
