This guide covers the side quests reported for Moonlighter 2: The Endless Vault Version 1.0, released 2 September 2026. The 1.0 update completes Will’s story and adds quests and other content, so older Early Access lists may not match the current game (official Version 1.0 announcement). The quest details below come from an unofficial guide updated 7 September 2026; use the in-game journal to confirm exact wording if a patch or localization differs.

Tasks are spread across Tresna, dungeon encounters, and shop customers. The most useful progression rewards include Andrei’s weapons, Julien’s backpack patches, and Nou’s material shop. Not every task is required to advance the main story.

Which side quests are worth prioritizing?

For a first playthrough, prioritize quests that unlock gear or persistent utility when their gates become available. The route below follows the reported progression order; optional errands and customer requests can wait unless their rewards suit your current needs.

  1. After defeating Herald, return to Tresna and complete Andrei’s Old Days, New Tech for the Sun and Moon Ballad gauntlets.
  2. After defeating the Curator in the Gallery, speak to Babyl to unlock the Blo-Beam recipe.
  3. Take Eris’s riddles when they appear and use her clue to seek the hidden treasure in the indicated map.
  4. At Vault II, free the Weird Prisoner to unlock Julien and the backpack patch system.
  5. If you want another spear option, pursue Babyl’s Tyke-dependent Rectifier recipe and the later Ray Axe chain when you meet its Aeolia and material requirements.
  6. Fit customer requests, furniture tasks, and Nou’s bulk order around your other goals; these are optional detours.

Andrei’s weapon quests

Andrei is Tresna’s blacksmith. His side quests provide weapon crafts, while the guide separately reports that biome armor sets unlock automatically after defeating each biome’s miniboss and returning to town. Those armor unlocks are not listed as side quests.

Old Days, New Tech: Sun and Moon Ballad

Defeat Herald, then bring Andrei the Sound of Hubris trophy. The reported reward is the Sun and Moon Ballad gauntlets.

Souls Forever Lost: Ray Axe

Visit Aeolia and obtain both King’s Masks: Senda’s Left and Monte’s Right. Julien then points you toward Andrei, who crafts the Ray Axe spear. The guide describes a further Souls Forever Lost 2 step after the first craft: bring the additional materials requested for the final recipe upgrade. Check the journal for the exact item list.

Eris’s errands and hidden-treasure riddles

Eris’s Errand

This is a repeatable material-collection task. The requested material changes; the guide says completing the delivery pays gold and a potion upgrade. Check the active request before setting out, since the needed material is not fixed.

Eris’s Riddle

The guide reports that a riddle becomes available after Vault I and another after Vault II. Follow Eris’s clue to locate a hidden treasure room or portal in the indicated map; rewards include recipes or weapons. The guide page does not provide a complete clue-by-clue solution list, so use the current in-game clue rather than relying on guessed room directions.

Rank #3
Moon Leap Boardgame 2~4 Players / 30min / Playte 14+ Over Ages.
  • In Moon Leap, players are trying to get their pawns as far down the track as possible in order to score the highest amount of points.
  • 14+ over ages.

Free the Weird Prisoner to unlock Julien

At Vault II—reported to unlock at 50,000 lifetime gold—the town board offers the option to pay 500 gold to free the Weird Prisoner. Doing so unlocks Julien and the backpack patch system. Patches can improve found quality, deluxe chances, or chest slots at later Vault ranks. Julien also directs you toward Andrei for the Ray Axe quest chain.

Babyl’s Curator and Tyke-related recipes

Babyl’s Request: Blo-Beam

After defeating the Curator in the Gallery, speak to Babyl to receive the Blo-Beam recipe. The guide recommends it as a ranged weapon against Thalaam and other flying enemies.

Rank #4
Oink Games Moon Adventure, Ages 10+, 2-5 Players, 40 Minute Playing Time
  • A challenging cooperative game based on Oink Games' worldwide hit "Deep Sea Adventure," selling over 200,000 units
  • Players work together as a team on a desperate mission to recover supplies on the moon
  • Will the crew be able to survive the magnetic storms and limited oxygen supply
  • Number of players: 2 to 5

The Rectifier

Babyl’s spear recipe requires Tyke’s Broken Rocket trophy. The guide does not give a separate trigger beyond that trophy requirement; check Babyl’s dialogue and the journal once you have it.

Nou’s delivery and bulk order

Nou appears in south Tresna after you meet him in a dungeon question-mark room.

Nou’s Delivery

Deliver the requested dungeon material to unlock Nou’s material shop. Confirm the required material in the quest entry before returning to the dungeon.

Nou’s Bulk Order

This request may appear after you have purchased from Nou for a while. According to the guide, accepting it trades a lower immediate sale for better stock or prices later; weigh that delayed benefit against the value of selling the goods now.

Shop customers and town tasks

After reaching Shop Level 2, customers may stand beside the register and ask for specific relics or materials. Delivering an order pays gold and reputation. The guide says ignoring a request has no mechanical penalty, so these are optional unless you want the payout or reputation.

The Countess and Doña Guita also give short furniture or showcase-arrangement tasks. The guide characterizes these as optional quality-of-life goals rather than progression gates.

What to do if a quest does not appear

  • Check the quest journal and current objective text; the guide’s trigger descriptions and item names may differ from your game after a patch or in another localization.
  • For boss- or trophy-gated tasks, confirm that you defeated the named boss and still have the required trophy. For the Ray Axe, verify both King’s Masks and any later requested materials.
  • For Julien, confirm Vault II is available and use the town board’s 500-gold release option.
  • For Nou, make sure you have met him in a dungeon question-mark room before looking for him in south Tresna.

The unofficial guide says quests persist on the save and trophy-gated weapons remain craftable if you keep the boss drops. Treat that as guide-reported rather than a developer-confirmed guarantee.
