Getting your hands on Monster Fluid is harder than it sounds in Monster Hunter Wilds. It's a game all about hunting monsters, after all, so you'd think all of them would give you whatever this mysterious juice is. If you want to craft certain weapons and armour though, you'll need to know where to find it.
Unlike most materials, you're unlikely to have a bunch of Monster Fluid bottled up and ready to go since it's not actually earned from hunting Wilds' big bads. I had to scavenge for some to make the second Bone Hatchets for my Dual Blades build, though plenty more gear needs it. Thankfully, it's actually really simple to get hold of.
