Comet arrived with the Astral Observatory update on August 22, 2026, and it is one of the few companions in Fisch that no vendor will ever sell you. It floats above your head as a dark, spiky little celestial body with big glowing eyes, and the only way to claim it is to catch it out in the world next to a fallen star with the right treat in your bag.
Quick answer: Complete Meteor Maniac Matthew’s first quest in Northern Expedition to receive Stardust Candy, then find Comet floating beside a fallen star during a Starfall and press E on the Offer Stardust Candy prompt.
Comet unlock requirements in Fisch
Everything below feeds Matthew’s quest except the fallen star itself, which is where the actual taming happens. Line all of it up before you go hunting, because walking up to Comet without Stardust Candy gives you no prompt at all.
| Requirement | Where it comes from |
|---|---|
| Meteor Maniac Matthew | Northern Expedition, on the raised platform near the Frigid Cavern camp |
| 1x Cosmic Relic | Break a Fallen Star with a pickaxe during a Starfall |
| 1x Moonstone | Meteors and Meteor Totems, an Ancient Isle asteroid, the Personal Aquarium, or the Daily Shop |
| 1x Solarblaze or Nova Frozen Walnut | Fish Overgrowth Caves for a Frozen Walnut carrying either mutation |
| Stardust Candy | Reward for handing all three items to Matthew |
| Level 30 | Unlocks the Companion Satchel so you can equip Comet later |
Note: a plain Frozen Walnut does not count. The quest only accepts the Solarblaze or Nova mutation, which come from the Wicked Fang Rod and the Rod of the Singularity respectively. You need one or the other, never both.

Find Comet at a fallen star and tame it
Comet is a roaming world encounter. It hovers near fallen stars scattered around the map, and its appearance at any given crater is random, so an empty impact site is normal rather than a sign that something broke.
E on the Offer Stardust Candy prompt.
How to confirm Comet was unlocked
The tame is confirmed by an on-screen popup reading Companion Unlocked: [Comet], and the companion drops straight onto your character’s head. From that point it lives permanently in your Companion Satchel, so you do not need a second Stardust Candy.
If no popup appears, the offer never went through. Three things account for almost every failed attempt.
- No Stardust Candy in your inventory, which means no offer prompt spawns at all.
- Confusing Companion Candy with Stardust Candy. Companion Candy only feeds companions XP and will not trigger the tame.
- Searching shops. There is no NPC stock or vendor listing for Comet, so browsing merchants is wasted time.
Equip Comet and what Astralux does
The Companion Satchel unlocks at Level 30. Open it with the C key, select Comet, and equip it. Only one companion can be active at a time, so Comet takes the slot from whatever you were running before.
Equipped, Comet grants the passive Astralux effect. Its description calls it a hyper celestial entity that hovers over your head and guarantees daily star showers, and in practice it raises the server-wide chance of rare meteor and Starfall drops. That means the boost helps everyone fishing on your server, not only you, which makes it worth keeping on while you farm astral materials.
The only real cost here is patience with the random spawn. Once the quest is done and the candy is in your bag, the unlock is a matter of checking craters until the right one has something floating over it.
