Listen up, fellow hunters. If you've spent more than five minutes in Monster Hunter Wilds' Oilwell Basin, you already know this place is hotter than a jalapeño's armpit. I'm not kidding. Step into the deeper subterranean zones and your health bar starts melting like butter in a skillet. The game doesn't politely ask if you'd like to take damage; it just does it. That's why Cool Drinks are your best friend, and Chillshrooms are the golden ticket to making them without bleeding zenny at the Supply Shop.
As of 2026, I've been roaming the Forbidden Lands since launch, and even after all the Title Updates and event quests, the Oilwell Basin still plays by the same rules. So here's my first-person, slightly singed guide to finding Chillshrooms and crafting Cool Drinks. Trust me, I've been roasted more times than a marshmallow at a scout camp.
Why You Need Cool Drinks (No, Really)
The Oilwell Basin is a lovely vacation spot if you're a magma monster. For humans with a pulse, the lower levels are a passive damage nightmare. Extreme heat ticks your health down while you're trying to carve a tail or chase a monster into a lava bath. Cool Drinks prevent that heat damage for a while. You can buy them from the Supply Shop after you encounter them during the story, but why pay when you can forage? Experienced hunters live off the land. I learned that the hard way after I carted three times because I forgot to restock. Don't be me. Don't be a crispy critter.
What Exactly Is a Chillshroom?
Chillshrooms are a rare type of mushroom you can find while exploring. They have a dull white cap and can only be found underground. They're not the flashiest ingredient in Monster Hunter Wilds, but they're worth their weight in gold when you're deep in the Basin. You can enter the wilds whenever you want by yourself or with friends by using the environment party link. It's always a good idea to gather ingredients for your potions and traps. Being prepared is an essential part of becoming a master hunter in Monster Hunter Wilds. Or, in my case, an essential part of not becoming a well-done steak.

Where to Find Chillshrooms in Oilwell Basin
Chillshrooms can only be found in one area in particular, and that is the Oilwell Basin. Head down to the lower levels and search areas 12, 13, and 14. Here's the route I use: follow the loop of water downward from area 14 as it twists into area 13. Along that watery loop, you'll find three Chillshrooms. Then check the small path east of area 13 heading toward the Limestone Cavern. That's where I usually snag a fourth. The map above shows you where to find Chillshrooms labeled by the red arrows, so you can't miss 'em unless you're trying to get roasted.

Pro tip: set down a Pop-up Camp in the Limestone Cavern. Once it's placed, you can fast travel here to quickly farm Chillshrooms and other materials. It's a rinse-and-repeat routine that'll fill your item box faster than you can say 'well done, hunter.' I've turned this little cavern into my personal mushroom factory, and I'm not ashamed.
Crafting Cool Drinks: One Mushroom, One Drink
If you have some Chillshrooms already, you can craft Cool Drinks immediately. Open your crafting list at your base camp tent or out in the field. Find the Cool Drink recipe in the potions tab and confirm to turn one Chillshroom into one Cool Drink. There's no reason not to have a full set of five Cool Drinks in your loadout ready to go when you're hunting. Most of the Oilwell Basin monsters can head downward into the hotter parts of the map, leaving you exposed to the extreme heat. And heat damage doesn't care about your DPS, your fashion, or how cool your weapon looks. It just ticks away.
Here's a quick cheat sheet for my fellow hoarders:
| Item | How to Get | Why It Matters |
|---|---|---|
| Chillshroom 🍄 | Gather in Oilwell Basin areas 12-14, water loop, east path near Limestone Cavern | Crafting material for Cool Drinks |
| Cool Drink 🧊 | Craft from 1 Chillshroom or buy from Supply Shop | Prevents passive heat damage |
| Pop-up Camp ⛺ | Place in Limestone Cavern | Fast travel farming hub |
My Personal Chillshroom Farming Loop
-
Fast travel to your Pop-up Camp in the Limestone Cavern.
-
Head out to area 13 and follow the water loop down toward area 14.
-
Grab the three Chillshrooms along the loop.
-
Take the small path east of area 13 toward the Limestone Cavern for the fourth.
-
Return to camp, rest, and repeat until your pouch looks like a beverage aisle.
-
Craft Cool Drinks like a mad scientist. Or a thirsty hunter. Same energy.
Sometimes RNG ain't on your side, and a monster decides to crash your farming session. Welcome to Monster Hunter Wilds. Either fight it or run like a coward. I won't judge. I've done both, sometimes in the same hunt. The environment party link makes it easy to bring friends, and more hunters mean faster gathering and fewer carts. If you're playing solo, just keep your head on a swivel and don't get greedy. A dead hunter gathers zero mushrooms.
Final Tips from a Slightly Crispy Hunter
-
Always carry five Cool Drinks. No exceptions. Not even if you're just 'quickly' passing through.
-
Gather Chillshrooms every time you pass through the Basin. Future you will say thanks.
-
Use the Pop-up Camp in Limestone Cavern as your farming base. It's a game-changer.
-
Buy from the Supply Shop only as a backup. DIY is cheaper and more satisfying.
-
If you see a monster heading downward, pop a Cool Drink before you follow. Heat damage doesn't care about your heroics.
-
Don't be ashamed to retreat. Living to gather another day is the real meta.
So there you have it. Chillshrooms might not be the flashiest thing in Monster Hunter Wilds, but they're your ticket to not becoming a crispy critter in the Oilwell Basin. As of 2026, this method still works like a charm. Now go forth, gather those dull white caps, and keep your Cool Drinks stocked. Your health bar will thank you, and so will your fellow hunters when you're not the one carting to heat exhaustion. Happy hunting, and stay cool. 😎
