How to get Aqua Sac in Monster Hunter Wilds
You get Aqua Sac by killing the Large Monsters Balahara and Uth Duna in Monster Hunter Wilds. Balahara is located is the Plains around areas 15 and 15, and Uth Duna is located the Forest in many areas, including areas 2, 5, 9, 10, 12, 13, and 15.
We've found the easiest way to find a Balahara or Uth Duna is to start an Optional Quest with Alma as part of her Quest Counter feature, then select the monster you wish to hunt and head directly to the region it's located in.
Keep in mind that as they are Large Monsters, Balahara and Uth Duna are very hard to kill, unless you come prepared.
We've got far more advice in the guides linked above, but in general, Balahara is vulnerable to Thunder elemental attacks, and attacking its weak points (Mouth, Tail, Head) is the most effective damage you can do. Uth Duna is also vulnerable to Thunder elemental attacks, and its weak points are its Mouth, Head, Tail, and Foreleg.
Uth Duna is also resistant to Water, so even if you can't use the Thunder element, avoid attacking it with Water-infused moves and items!
Remember, you're not guaranteed to get Aqua Sac by killing Balahara or Uth Duna, as there's only a small chance they drop Aqua Sac. And it's also worth keeping in mind that Aqua Sac can only be obtained at Low Rank, as you instead get Torrent Sac from killing Balahara or Uth Duna in High Rank.
As always, keep in mind that you can also check which monsters give you Aqua Sac by looking through their individual entries in your Small Monster Field Journal.
