Genshin Invasive Fish Wrangler Co‑Op Guide: Rewards, Buffs, And High Score Tips

Invasive Fish Wrangler is a limited‑time multiplayer fishing event in Genshin Impact Version 5.4 “Moonlight Amidst Dreams,” featuring Co‑Op and Fish‑Off modes where you spend Action Points to throw nets, earn Wrangler Points, and unlock Primogems plus Fontaine upgrade materials. In co‑op, up to four players share a stage and try to catch as many fish as possible before their collective Action Points or the timer runs out, with larger fish and special glowing fish giving much higher scores. If your goal is to grab all limited Primogems, you need to push your Wrangler Points to 3,000 across both modes, which yields 420 Primogems from milestones, while also clearing a handful of one‑time “Special Action” objectives for bonus materials and unique fish.

For efficient farming: focus co‑op runs on consistently catching multiple large or glowing fish per throw, assign simple roles so players don’t overlap nets, and dedicate one or two runs to cleaning up the size‑specific Special Actions instead of trying to do everything at once. You only need to enter Fish‑Off once to clear its Special Action, so you can safely treat it as a side task after you’re comfortable with the co‑op fishing rhythm.

How to play co‑op and grab the main rewards

1. Unlock the event by reaching at least Adventure Rank 20 and clearing the Mondstadt Archon Quest “Song of the Dragon and Freedom,” then talk to Jala near Fort Charybdis Ruins in Fontaine to open the Invasive Fish Wrangler menu.

2. Enter Co‑Op Mode from the event screen, join or host a room with up to four players, and choose a stage.

3. Watch the Action Point gauge and use Small, Medium, and Large nets that match the size of fish clusters; prioritize large and glowing fish for the best scores.​

4. Farm co‑op stages until your total Wrangler Points reach 3,000 to claim all six Primogem milestones and Fontaine upgrade materials.

5. While farming, deliberately complete Special Actions like catching fish with specific net sizes, grabbing Marvelfish, and landing at least one Super Large Fish.

6. Play at least one Fish‑Off match from the event menu to clear its Special Action and pick up extra rewards.

How to unlock Invasive Fish Wrangler and when it runs

Invasive Fish Wrangler is part of Genshin Impact Version 5.4 “Moonlight Amidst Dreams,” which rolled out on February 12, 2025, and includes a multiplayer fishing game among its limited‑time events. The fishing event is available during Phase 2 of the patch, and its banner and in‑game description clearly label it as a co‑op multiplayer fishing challenge.

To enter the event, you need:

• Adventure Rank 20 or higher.

• Completion of the Archon Quest “Song of the Dragon and Freedom” in Mondstadt.

Once you’ve met those requirements, you can access the event by interacting with the quest marker near Fort Charybdis Ruins in Fontaine’s Morte Region and then selecting “Invasive Fish Wrangler” from the event menu.

Co‑op vs Fish‑Off: what changes and why it matters

Both modes use the same core fishing system but reward you a bit differently.​

Co‑op mode basics

In Co‑Op Mode, you and up to three other players share a stage and pool your efforts for a collective score. Everyone spends from a shared Action Point pool by throwing nets, and the challenge ends when time runs out or you run out of Action Points. Your final Wrangler Points depend on how many fish you catch, how big they are, and whether you snag bonus glowing fish.

Fish‑Off mode basics

Fish‑Off Mode is a competitive queue where players fight for the highest points in a match. In this mode, your rank at the end of the round and the tier of the challenge decide how many points you bring home, and you cannot queue as a pre‑made co‑op team. Importantly, you only need to play one Fish‑Off game to clear the “Play in Fish‑Off Mode” Special Action, which is enough for the associated reward bundle.​

Nets, Action Points, and glowing fish explained

Each run gives you a fixed number of Action Points, which you spend whenever you throw a net. You don’t refill this resource during a round, so every throw needs to hit several fish if you want high scores.

You have three net types, each scaled to fish size:

• Small Net: low cost, best for dense groups of small fish.

• Medium Net: balanced cost and radius, ideal for mixed clusters.

• Large Net: high cost, but needed to consistently catch large and Super Large fish.

On top of size, some fish glow and give special bonuses. A green glow lets you buff your Small or Medium net so you gain more Action Points from subsequent catches, while a gold glow gives five times the normal points for that fish size. Community high‑score runs often open by hunting glowing fish first, then shifting focus to big clusters once buffs are active.​​

Invasive Fish Wrangler rewards and total Primogems

You earn rewards through Wrangler Point milestones and Special Action objectives.

Wrangler Point milestones

Wrangler Points accumulate across both Co‑Op and Fish‑Off, with six key milestones:

• 500 Wrangler Points – Primogems ×70, Phony Bejeweled Unihornfish ×1, Chapter of an Ancient Chord ×3, Mora ×20,000

• 1000 Wrangler Points – Primogems ×70, Phony Bejeweled Unihornfish ×1, Sublimation of Pure Sacred Dewdrop ×3, Mora ×20,000

• 1500 Wrangler Points – Primogems ×70, Phony Bejeweled Unihornfish ×1, Wine Goblet of the Pristine Sea ×3, Mora ×20,000

• 2000 Wrangler Points – Primogems ×70, Phony Bejeweled Unihornfish ×1, Chapter of an Ancient Chord ×3, Mora ×20,000

• 2500 Wrangler Points – Primogems ×70, Phony Bejeweled Unihornfish ×1, Sublimation of Pure Sacred Dewdrop ×3, Mora ×20,000

• 3000 Wrangler Points – Primogems ×70, Phony Bejeweled Unihornfish ×1, Wine Goblet of the Pristine Sea ×3, Mora ×20,000

Clearing all six milestones gives you 420 Primogems in total, plus plenty of Fontaine weapon and ascension materials.

Special Action objectives

Special Actions are one‑time tasks like catching certain fish types or using specific nets that give bonus rewards:

• Catch 5 Marvelfish – Phony Bejeweled Unihornfish ×1, Mystic Enhancement Ore, Mora ×20,000

• Catch 10 Large Fish using Large Net – Phony Bejeweled Unihornfish ×1, Sanctifying Unction, Mora ×20,000

• Catch 10 Medium Fish using Medium Net – Phony Bejeweled Unihornfish ×1, Sanctifying Unction, Mora ×20,000

• Catch 10 Small Fish using Small Net – Phony Bejeweled Unihornfish ×1, Sanctifying Unction, Mora ×20,000

• Catch 1 Super Large Fish – Phony Bejeweled Unihornfish ×1, Mystic Enhancement Ore, Mora ×20,000

• Play in Fish‑Off Mode (1 time) – Phony Bejeweled Unihornfish ×1, Hero’s Wit, Mora ×20,000

These objectives don’t add more Primogems but pad out your materials and give you a healthy stock of the event fish.

High‑score co‑op strategy: how to push Wrangler Points fast

If you’re aiming to clear 3,000 Wrangler Points quickly, you want consistent high‑value runs instead of gambling on solo hero plays.

Simple team roles

You don’t need perfect coordination, but a loose role system helps:

• Spotter: stays near the center, calls out directions (“big glow left,” “small swarm bottom”).

• Big Catcher: mainly uses Large Nets on large and Super Large or golden‑glow fish.

• Sweeper: uses Small and Medium Nets to clear leftovers in the wake of big throws.

• Flex: fills whichever role is needed depending on spawns.

The idea is to avoid two players spending Action Points on the same group when one net would have done the job.

Throw timing and net selection

From gameplay footage and written guides, a few habits clearly separate high scores from average ones:

• Wait for clusters: give fish a moment to bunch up so your net always hits three or more targets.

• Match net to the majority: use the net that fits most of the school, not just the biggest fish in it.

• Respect Action Points: avoid throw spam; if you’re not catching multiple big or glowing fish, you’re wasting points.

Spend early throws hunting green‑glow fish to buff your nets, then switch to farming large clusters and golden‑glow fish for huge point spikes.​​

How to clear Special Actions while farming

You can combine most Special Actions with normal co‑op farming so you don’t need many extra runs.

• Run 1–2: play normally with a focus on large and glowing fish; you’ll likely get your first Super Large Fish and some Marvelfish without trying.​

• Dedicated small/medium runs: once the big‑fish tasks are done, organize a room where one player focuses only on Small Nets and another on Medium Nets until their “catch 10” goals are cleared.

• Fish‑Off cleanup: queue Fish‑Off once when you’re comfortable with the mechanics, knock out its Special Action, then go back to co‑op if you prefer.

If you’re coordinated, you can be done with every objective well before hitting 3,000 Wrangler Points, which lets your remaining runs be pure Primogem and material farming.
