Crafting elemental weapons inMonster Hunter Wildsis essential for more comfortable endgame progression, and you’ll need materials like the Aqua Sac to start the process for certain Water and Thunder weapons. Unfortunately, getting even a few Aqua Sacs takes some additional effort, as it’s a rarer material unique to only a pair of monsters.
Once you know where to look, though, gathering Aqua Sacs is a straightforward, if time-consuming, process. We’ll show you where to look and what to do in this guide, specifically the monsters you’ll need to be hunting if you’re after the weapon of your dreams!

Where To Get Aqua Sacs
TheAqua Sacis a somewhatuniquemonster material. You canonly get itas atarget rewardforslaying or capturingaBalaharaor anUth Duna. Youcan’t get themfromcarvingorbreakingthe monster’s parts. Worse, thechance to get an Aqua Sac is relatively lowcompared to other materials you might be hunting for.

You’llfirstencounter BalaharainChapter 1-4during the assignment Balahara of the Sandsea. You fight, but do not slay,Uth Duna in Chapter 1-5during the missionA Feast in the Deep.

To farm either monster,speak to Almaand start theOptional Quests Sand Sea Surgesfor Balahara orVeiled by the Tidefor Uth Duna.
Aqua Sac is a Low Rank reward, meaning youwon’tbe able tofarm it in High Rankquests or the High Rank open world once you’ve completed the Low Rank story campaign. Youneed to enter Low Rankquests to access the Low Rank open world.
Between the two monsters,we recommend farming Balaharain the one-star quest Sand Sea Surges. There are a few reasons, but the main one is that, as anearly game quest,the gear you use to fight it willquickly out-classits attacks and defenses.
Being overgeared ensures a single questhuntingaBalahara shouldn’t take more than a few minutes. Additionally, becauseUth Duna is a larger monsterwith a lower chance at an Aqua Sac, fighting it over a Balaharais less efficient.
What You Can Make With Aqua Sacs
As a Low Rank material,Aqua Sacswill only let youmake up to Rarity 4 gear. Most higher-quality weapons require that you have the lower-rarity version, however. That meansif you want Rarity 5 and above weapons, you need tofirst craft the weaker stuffyou’d use materials like Aqua Sacs to make.
Specifically, you canmake the following gear with Aqua Sacs:
If youwant to make everythingthatrequiresanAqua Sac, you’llneed nineof them. Depending on your luck and patience levels, it couldtake as little as a half hour to forty-five minutesif you hunt Balahara with high-quality gear.
If you’refarming Aqua Sacswithlower-rank gearor similar quality weapons and armor, expect eachhunt to take at least seven minutesor so.
