Mr Goodnight is one of the neutral Geniemon in Duet Night Abyss, and it fills a very simple role: keep you alive. It’s an active, Gold-rarity pet with a sustained heal and a small all-round stat buff, and it appears early in the story on Purgatorio Island, long before the rest of the game opens up.
Duet Night Abyss Mr Goodnight stats and role
Mr Goodnight doesn’t align with any element, so you can slot it into any team without worrying about elemental synergy. It is flagged as an active Geniemon, meaning you can call on its support skill in combat rather than treating it as a purely passive stat stick.
| Attribute | Value |
|---|---|
| Type | Geniemon (pet) |
| Element | Neutral / No Element |
| Rarity | Gold |
| Active or Inactive | Active |
Because it’s neutral, Mr Goodnight is a safe default choice if you have not yet built out a full elemental roster of pets. Its real value, though, comes from what its support and passive skills actually do.

Duet Night Abyss Mr Goodnight abilities (support and passive)
Mr Goodnight specialises in sustained recovery. Instead of a single large burst of healing, it applies a heal-over-time effect to your whole party, and layers a small but useful all-stat boost in the background.
| Skill | Effect at Lv. 1 |
|---|---|
| Support skill | Continuously restores 2.7% of each affected character’s Max HP per second for 10 seconds, healing both Mr Goodnight and allies. |
| Passive skill | Increases ATK by 1.8%, Max HP by 1.8%, and DEF by 1.8%. |
Across the ten-second window, the support skill sums to roughly 27% of Max HP recovered per character if the full duration plays out. That makes Mr Goodnight especially useful in longer encounters and exploration content where you’re taking chip damage rather than sudden lethal bursts.
The passive buff is modest but broad: a small increase to both offense and survivability that’s always on once Mr Goodnight is equipped. Since it scales off your existing stats, it stays relevant as your characters grow.

Duet Night Abyss Mr Goodnight variants and shinies
Like other Geniemon, Mr Goodnight can appear in multiple variant tiers, including cosmetic “shiny” and rarer forms. All three listed versions share the same core identity and role.
| Variant | Notes |
|---|---|
| Shiny Mr Goodnight | Shiny-tier appearance variant. |
| Ardent Mr Goodnight | Ardent-tier variant. |
| Miraculous Mr Goodnight | Highest listed variant tier for this Geniemon. |
The available information focuses on appearance and variant labels rather than distinct stat lines, so you should treat all Mr Goodnight forms as the same pet concept, with rarity primarily driving progression potential rather than reworking its basic kit.
Duet Night Abyss Mr Goodnight location on Purgatorio Island
Mr Goodnight is tied to Purgatorio Island, the game’s prologue area. There is currently one tracked spawn in the Filthoid-Ravaged Village section of the island, which lines up with an early story beat.
| Region | Sub-area | Spawn details |
|---|---|---|
| Purgatorio Island | Filthoid-Ravaged Village | Found outside the house where Berenica and the main character discover the sword during the opening chapter. |
At a higher level, tracking tools list Mr Goodnight as a single known instance on a single map, which matches this Purgatorio Island spawn. Some players also point out another Mr Goodnight in the area associated with the Psyche fight on the island, reachable via the farthest teleport point and easier to locate by using Bro Boxie. That still falls within the Purgatorio Island context rather than opening up an entirely separate region.

How to capture Mr Goodnight in Duet Night Abyss
Mr Goodnight is not locked behind gacha or progression rewards; it is obtained through the overworld capture system using treats. Once you reach the Filthoid-Ravaged Village segment on Purgatorio Island and spot the creature outside the story-important house, you can move straight into befriending it.
| Step | What to do |
|---|---|
| 1. Reach the village | Progress the main story on Purgatorio Island until you enter the Filthoid-Ravaged Village and complete the scene where Berenica and the protagonist find the sword. |
| 2. Locate Mr Goodnight | After that scene, look just outside the same house; Mr Goodnight patrols in that immediate area. |
| 3. Prepare treats | Make sure you have Geniemon treats in your inventory. Treats come in multiple rarities; higher grades increase your success chance when attempting to capture. |
| 4. Initiate capture | Approach Mr Goodnight and start the capture interaction, then feed it one or more treats as prompted. |
| 5. Confirm ownership | Once the capture succeeds, Mr Goodnight is added to your Geniemon list and becomes available as an active pet with its support and passive skills. |
If you’re struggling to visually pick it out in the village, tools like Bro Boxie can help locate nearby Geniemon. Comments from players specifically recommend using Bro Boxie around the furthest teleport point on Purgatorio Island in the area where Psyche is fought; this can highlight Mr Goodnight, along with other pets in the vicinity.
Tracking Mr Goodnight with an interactive map
For players who want to see the exact pin on a world map rather than combing the village manually, interactive map tools for Duet Night Abyss include a dedicated Mr Goodnight marker on Purgatorio Island. These maps typically show:
| Map | Mr Goodnight count | Usage |
|---|---|---|
| Purgatorio Island | 1 tracked Mr Goodnight | Use the pin to navigate to the Filthoid-Ravaged Village spawn and mark it as discovered once captured. |
On these maps, right-clicking (or the platform equivalent) on the Mr Goodnight icon usually toggles a “discovered” state, letting you track which Geniemon you’ve already collected as you work through the island.

Mr Goodnight is straightforward: one early-game location, a single capture flow, and a simple but effective healing kit. If you want a reliable neutral pet that smooths out incoming damage without forcing you into a particular element, grabbing Mr Goodnight on Purgatorio Island should be one of your first stops.
