Invasive monsters are special enemies in Monster Hunter Stories 3: Twisted Reflection that are stronger than normal monsters and need a special strategy to make them retreat. You will find them at night, hidden in remote parts of the map. These fights are important because defeating them will open their dens, where you can collect endangered monster eggs. Many of these eggs can hatch into rare monsters, including subspecies and powerful variants. In this guide, we will tell you all the Invasive Monsters Locations in Monster Hunter Stories 3.
All Invasive Monsters Locations

Invasive monsters are some of the toughest monsters you can find in the game. These monsters usually appear only at night, hide in difficult places, and are stronger than regular monsters. Once an invasive monster retreats, its den becomes available, and that gives you access to endangered monster eggs, including rare subspecies and special variants.
Invasive Yian Garuga


You can find the Invasive Yian Garuga in Sunpedal Plains in Azuria, on the eastern side of the map, near the lookout point and the Sunpedal Plains path Catavan stand. To defeat it, break its legs until it weakens and falls over. Once you deal a lot of damage, it will run back to its nest. You can use a great sword or a long sword to defeat him. You will get an endangered Rathian egg as a reward.
Invasive Arzuros


Arzuros will appear at Blessing Hill in Canalta Timberland, near the southern edge of the area. During the battle, Arzuros will summon other small Arzuros, which will use up its honey supply. Defeat the small Arzuros whenever they appear, so it keeps spending honey until it has nothing left. Be careful of its Invasive Honey Rush because it can deal a lot of damage to your party. When its honey supply is empty, it will run back and leave behind an endangered Canine egg.
Invasive Plesioth


It is hidden in an underground cavern, north of the small island, at Mirror Lake in Azuria. Go through the narrow water channel near the Catavan stand to reach it. Bring a fire-element monster, a fire monster to deal a lot of damage. Use Gunlance because its explosive attacks work against Plesioth. After some time, its head sacs will start to glow. This is the perfect time to use a fire attack on its head. Once you deal a lot of damage it will retreat and leave behind an endangered Lagiacrus egg.
Invasive Seregios


Seregios is found northwest of the Mirror Lake in Azuria. From the small island at Catavan stand, swim to the nearby winddraft. Now use your flying monster and fly up to the cliff. You need to use Perfect Crush, as normal attacks will not work against it. When Seregios comes for a head-to-head attack against your rider, use Perfect Crush. You can then collect an endangered Astalos egg from its den.
Invasive Nerscylla


Nerscylla is located in the southeast part of the Canalta Timberlands near Blessing Hill. From the tent camp, go towards the east across the ledge and follow the river towards the lake. When Nerscylla targets you with Invasive Death Scissors, use Wyvern Blaze. When it retreats, it will reward you with an endangered Nargacuga egg.
Invasive Odogaron


Odogaron is in a secret area at Rooko Rocks in Tarquon. Go to the Catavan stand at night. Then go southwest and glide towards the tallest wind draft. Then reach the hidden ledge on the cliff. Use the Almudron as it deals a lot of damage to Odogaron. Use Muddy Hell, which covers Odogaron in mud and deals water damage over several times. Use the Mud effect when Odogaron uses Crimson Claw. When it retreats, it leaves behind an endangered Zinogre egg.
Invasive Shogun Ceanataur


Ceanataur is hidden behind a waterfall in Canalta Timberlands. From the Howly Forest Camp, go east to the river and then follow it north until you find the waterfall cave. During the battle, wait until it targets one of your allies. On that turn, use Armourskin or Mega Armourskin on the ally. Its attack will bounce off, which will force it to retreat. You can then collect an endangered Mizutsune egg.
Invasive Diablos


Diabolos is found in a canyon in the southern part of Colossal Dragon’s Remains in Tarquon. From the southeast observation tower, move south along the eastern edge until you reach the canyon. Use a hammer with Meteor Hammer. When the battle is in the second phase, Diabolos create three holes in the ground. Watch the dust pattern to see from which hole it will come. Then attack the hole with Meteor Hammer. This will retreat, and you will get an endangered Tigrex egg.
Invasive Khezu


Khezu is located in the northern part of Glacial Caps Iceberg in Sarrathus, east of the camp. From the observation tower, go towards the jellyfish area and climb across the rocks. Khezu will start the attack with technical attacks, then switch to power attack when he is angry, before he uses Wyvern Soul Eater, use a kinship skill to interrupt that attack. This will retreat Khezu, and you will get an endangered Barioth egg.
