Soulseer Mizutsune in Monster Hunter Stories 3 is one of the rare Deviant monsties players can unlock in Twisted Reflection. Unlike normal monsties that appear in random dens, this Leviathan variant only becomes available after you set up a habitat where two rival species coexist.

The process spans multiple zones and also involves dealing with invasive monsters and habitat rankings. Because of that, many players miss one of the steps and never see the egg appear. This guide explains how to unlock Soulseer Mizutsune in Monster Hunter Stories 3 and what you need to do to get it.

How to Get a Mizutsune Egg in Monster Hunter Stories 3

The first thing you need is a regular Mizutsune. Travel to Canalta Timberland and locate the invasive Shogun Ceanataur encounter that guards the area. You will not be able to obtain Mizutsune eggs until this monster retreats.

During the fight, you need to block the monster’s major attack using defense buffs or similar protective skills. Once the attack is deflected, the monster retreats and a nearby den becomes accessible.

Search the den to obtain a Mizutsune egg. After hatching it, release the monstie into a habitat zone through the ecosystem restoration system. This step allows Mizutsune eggs to start spawning in that region.

If Mizutsune is not placed into a habitat, the mutation will never occur and the Deviant variant will not appear later.

Next, you need to obtain a Zinogre egg. Mizutsune’s rivalry with Zinogre is what triggers the mutation that eventually leads to this Deviant variant.

Travel to the game’s third zone and locate the invasive Odogaron encounter that guards the Zinogre den. This fight typically appears at night.

During the battle, focus on breaking Odogaron’s claws while applying mud effects beneath it. When the monster slips and retreats, a den becomes available where Zinogre eggs can be collected.

Once you hatch a Zinogre, release it into the same habitat where Mizutsune was placed earlier. Both species must live in the same ecosystem for the mutation to happen.

Once both monsters are placed in the same habitat, you need to start improving the ecosystem rank. The fastest way is by repeatedly hatching and releasing additional Mizutsune eggs into that habitat. Releasing additional Zinogre eggs can also help the ecosystem rank increase faster.

Your main goal is to push Mizutsune’s ecosystem level to Rank S in that shared zone. When Mizutsune reaches Rank S while Zinogre is present, the mutation finally occurs.

At that point, Soulseer Mizutsune in Monster Hunter Stories 3 begins appearing as a possible egg inside the dens of that habitat.

This same condition can also unlock another Deviant variant, Thunderlord Zinogre.

After the mutation becomes active, explore egg dens in the habitat where both species were released. Not every egg you find will contain Soulseer Mizutsune, so you may need to check several dens before discovering the correct one.

Once you hatch the egg, the monstie becomes part of your roster.

As a Deviant variant, Soulseer Mizutsune generally deals much more damage than the base Mizutsune.

In battle, it focuses on burn-synergy attacks and critical damage setups.

One of its main abilities can apply burn while also lowering the enemy’s accuracy. After inflicting burn, follow-up attacks can deal increased damage to the affected target. Because of this, the monster performs better in longer fights where burn effects stay active.

Along with its combat abilities, Soulseer Mizutsune also provides several useful riding actions:

  • Swim
  • Jump
  • Roar
  • Breath
  • Melee Attack

These abilities make it helpful both in exploration and combat, especially if you are planning to use Soulseer Mizutsune in Monster Hunter Stories 3 for longer hunts.
