All monster mutation variants in Monster Hunter Stories 3 and how to get them

by

In Monster Hunter Stories 3: Twisted Reflection, you can collect lots of unique monstie variations, and you’re able to begin searching for them relatively early in the game.

Throughout the world of Monster Hunter Stories 3, you’ll find monsters with unique mutations to discover in each of the four regions. These mutations are closely tied to the game’s Invasive Monsters (we’ll explain those later!). This guide will show you how to unlock and collect every mutated endangered species during your journey.

How to get all monstie mutation variants in Monster Hunter Stories 3

I’ve organized the mutation variants into four separate tables, one for each region, because variants were found in all of them. Each table provides detailed information specific to its region and also includes mutations found in native species where relevant.

Azuria

Variant How to Get
Pink Rathian To get the Pink Rathian mutation, you need to defeat the Yian Garuga and release the Rathian from the clutches of its Invasive predator.
Dreadqueen Rathian First, you need the Rathian or Pink Rathian’s Ecoystem Rank to be S. Then, it should be in the same region that has three poison monsties. The region of Sunpetal Plains already has Gypceros, and you’ll get Rathian and Pink Rathian in the same region.
Ivory Lagiacrus Get a regular Lagiacrus’ Ecosystem Rank to A in any region.
Boltreaver Astralos Get Astalos’ Ecosystem Rank to S. It should also reside in thunder elemental areas that have three or more thunder elemental monsters. Only monsties with base thunder elements can qualify for this requirement.

Canalta Timbaland

Variant How to Get
Green Nargacuga Get Nargacuga’s Ecosystem Rank to A.
Silverwind Nargacuga You have to get Nargacuga or Green Nargacuga’s Ecosystem Rank is S. You’ll also need it to reside in an area that has two or more monsters who can control the winds. Some examples include the Legiana, Great Izuchi, and Paolumu.
Soulseer Mizutsune You need to get your Mizutsune’s Ecosystem Rank to S.
Deadeye Yian Garuga Get the Yian Garuga’s Ecosystem Rank to S. The creature also needs to have three or more monsties that have equal or greater rank than the Yian Garuga (the Ecosystem Rank).

Thunderlord Zinogre Get the Zinogre or Stygian Zinogre’s Ecosystem Rank to S. You also need the monstie to reside in a habitat that has one or more endangered species with enchanting, purple fur and considered bitter rivals of the Zinogre. The Soulseer Mizutsune can qualify for this requirement.
Brute Tigrex Get the Tigrex’s Ecosystem Rank to A.
Grimclaw Tigrex You need to get Tigrex or Brute Tigrex’s Ecosystem Rank to S. The creature should reside in a habitat that has four or more Power Type monsters. Your best option is to choose the Colossal Dragon’s Remains area as there are two native Power type in this region.
Hellblade Glavenus Get the Glavenus’ Ecosystem Rank to S. The monstie should reside in habitats with four or more monsties that have appendages, like the Shogun Ceanataur, Seregios, Great Izuchi, and Magnamalo.
Bloodbath Diablos Get the Diablos or Black Diablos’ Ecosystem Rank to S. The creature must reside in its native habitat in Tarkuan’s Bountiful Dunes.

Seranthis

To get the best mutations, you’ll need to find eggs from endangered species. But protecting those eggs means keeping invasive species away, which can be a really difficult task.
