In Crimson Desert, the trial “Mystical Ecosystem” is part of the questline involving a sealed Abyss artifact. To complete it, you need to find and catch three creatures named Choppi. The easiest place to do this is in the Abyss zone “Archive of Axioms”—the first sky island you visit during the main story.
Location of the sealed Abyss artifact “Mystical Ecosystem”: look for it on an altar west of the Pailun Locks, just south of Pailun city. You’ll spot a small wooden roadside shrine surrounded by cats.
How to catch 3 Choppi in Crimson Desert
Choppi are tiny white rabbit-like creatures with big pointed ears and black-tipped paws. They only appear in a handful of spots. The quickest way to track them down is to head to the Abyss “Archive of Axioms,” the area where you first gain the “Axiom Force” ability during the quest “Polar Opposites.”
Open the map and center the camera on the city of Ernand.
Once the trial is complete, open your inventory and select the glowing white sealed Abyss artifact to convert it into a regular Abyss artifact.
The first time you catch one of these white “bunnies,” an entry for Choppi will appear in the “Mysterious Creatures” section of your journal under “Knowledge.” Turns out these fluffy critters are actually chimeras, not real animals, which is why they’re so hard to spot on the surface.
