To get a Molten Tigrex Egg, you must first update Monster Hunter Stories 2: Wings of Ruin to 1.4.0. Once done, you need to interact with A Quest Board in any village and click on Multiplayer.
Click on the online game, go to the Expeditions tab and locate the quest (Explorer) dragon eggs. This is an 8 star quest and is easier to do online than in co-op with a friend or random person. You can do this solo and get an AI friend to help you, but the AI companion is useless compared to a real person.
Once the quest is selected, press OK, choose your expedition ticket. We recommend using an SR Expedition Ticket as it gives a higher chance of acquiring a Rare Egg, or in this case, the Molten Tigrex Egg, but there is no guarantee.
Explore the area and locate Molten Tigrex's lair. If you don't want to fight anything on your travels, bring a Nargacuga and use its stealth monster ability so you don't get mugged by monsters. You will arrive at your destination in peace.

Molten Tigrex is a brutal fight, but did you expect anything less from a rare species of Tigrex? The enemy has a huge health pool and uses multiple powerful attacks in a row. This can quickly wipe out your team if you don't prepare for the onslaught.
You need to pay attention to two main movements. Savage Roar which transforms into Deafening Roar which changes Molten Tigrex to Technical, and Wild Spear, which after a few turns will become downed and then revert to Power, their original state.
|monstre||Type of attack||To counter||Element Weakness||Physiology and weakness of parts|
|Molten Tigrex||Initial: Power
After a Deafening Roar: Technique
After being shot: power
After a deafening roar: power
After being shot: speed
When Molten Tigrex has been defeated, you can then loot the nest for eggs. Due to Molten Tigrex being a rare form, the egg changes slightly from its base form. Use the image below to know exactly which egg you are looking for: the egg is blue and white instead of blue and red.
As usual, head to the den exit with your prize and make sure the egg is stocked. Then go hatch it to see if you were lucky enough to get Molten Tigrex as Monstie. Otherwise, rinse and repeat.
