The Fifth Trial of Aql in Dune: Awakening is hidden in an unassuming location somewhere near the upper-middle part of the Hagga Basin. Granted, all the trials are hidden off the beaten path, but this one is especially so. Regardless, once players finish this trial, they’ll be able to unlock an important of warfare in Arrakis while also opening the path to the remaining trials somewhere in the desert.
Completing the Fifth Trial of Aql is quite similar to the earlier ones. Sniff some Spice, dream a weird dream, and come back stronger and wiser. If you’re wondering where the Fifth Trial takes place, here’s a short guide to help you out.

For those diving into the sands of Dune: Awakening, here are some useful beginner tips to help them in their adventure.
Where is the Fifth Trial of Aql in Dune: Awakening?
The fifth Fremen trial is located underground. You can access it by heading east of the Hagga Rift and finding the Hidden Test. The entrance to the Hidden Test is a hole next to a large rock formation that’s jutting out diagonally from the ground. Climb down the hole (or jump down while using a Suspensor Belt), then follow the path to the altar containing yet another bowl of Spice.
Take note that you must complete the Trials of Aql in order. If you come here without completing the fourth trial, the game will tell you to come back later. You can find the Fourth Trial of Aql inside the head of Mizrabah’s Hammer, the large, hammer-shaped rock formation in Vermillius Gap.
Be careful when crossing the border between Vermillius Gap and Jabal Eifrit — there are a lot of quicksand patches there, and if you get trapped in one, you’ll likely end up getting eaten by a worm.
Fifth Trial of Aql Walkthrough
In this trial, players will be reintroduced to Shai-Halud, also known as the sandworms of Arrakis. All you need to do here is to cross each room while avoiding the sand, which should be easy enough to do.
In the final area of the trial, you’ll be presented with a Thumper, a device that the Fremen use to summon sandworms to an area. Pick up the Thumper, then place it somewhere near the vehicle in front of you. Once the Thumper is on the sand, immediately run up the stairs next to you. A sandworm will soon burst from the sand below the vehicle and swallow it whole.
Once you finish the Fifth Trial of Aql, you’ll get the crafting schematic for the Thumper as a reward. You can use it on open sand to attract sandworms to that specific area, and they’ll swallow anything unfortunate enough to be on top of them as they emerge.
