Oilwell Basin Region Overview and Guide in Monster Hunter Wilds

The Oilwell Basin is the third area you will explore and one of the more extreme environments in the Forbidden Lands, filled with bubbling tar pits, scorching geysers, and deep underground caverns. It is a harsh, unforgiving landscape, home to powerful creatures that have adapted to the intense heat and toxic fumes. If you are going to hunt in this zone, you need to come prepared, as the region’s hazards can be just as deadly as its monsters.

The region experiences an Inclemency known as the Firespring, where intense fires ignite across the landscape, creating a hazardous environment for hunters.

• Explosive Geysers: These can launch you into the air or damage nearby creatures; use them strategically!

The Oilwell Basin is the third area that hunters unlock, and is also affected by three different weather states:

• Plenty
• Fallow
• Firespring: During this Inclemency, the entire area is engulfed in flames, drastically increasing ambient temperatures and igniting oil pools.

• Avoid Tar Pits: They slow movement and leave you vulnerable to attacks.

Once a big mining hub, the Oilwell Basin has become a hostile and unstable region due to ongoing volcanic activity. Pools of thick oil bubble up from beneath the ground, and geysers of superheated steam erupt without warning. The Azuz tribe has learned to work with the land, harnessing its geothermal energy to power their Everforge; a vital tool for crafting weapons and armor. While the area is filled with remnants of ancient machinery, it is also said to be home to creatures that lurk deep within the caves, guarding secrets lost to time.
