Genshin Impact’s Natlan region hides a clever little mystery in the Collective of Plenty tribe, where players can unlock “The Murderer Is… You!” achievement by investigating a series of unusual incidents. This lighthearted whodunit doesn’t involve any actual murder – just a mischievous young Tatankasaurus causing trouble throughout the village.

Starting the Investigation
Begin your detective work in the main area of the Collective of Plenty tribe. You’ll need to speak with three different villagers who have fallen victim to the mysterious troublemaker. The order you visit them doesn’t matter, but each requires selecting specific dialogue options to progress the investigation.

Victim #1: Xona the Blacksmith
Find Xona near her workshop and choose the dialogue option “The fence here seems to be broken…” She’ll explain how a rampaging Saurian destroyed her fence, though she seems remarkably calm about it. This option disappears after selection, so don’t miss it!
Victim #2: Xoctli at the Granary
Head southeast to the granary where Xoctli is struggling with food transport issues. Select “Need any help?” to hear his complaints about a Saurian disrupting his work. His testimony adds another piece to our growing puzzle.
Victim #3: Ixcatl’s Training Woes
Further east, you’ll find Ixcatl frustrated about his ruined training session. Choose “Get away?” to learn how a rogue Saurian interrupted his practice. With all three testimonies collected, the pattern becomes clear.

Confronting the Culprit
Now head north to find four villagers gathered around Pisasa, a young Tatankasaurus. Interacting with the scene reveals this was the troublemaker all along – breaking fences, disrupting work, and ruining training sessions. The villagers’ lighthearted scolding completes our mystery.
Claiming Your Reward
After revealing Pisasa as the culprit, you’ll immediately unlock “The Murderer Is… You!” achievement. It’s a charming nod to detective stories, though thankfully without any actual crime involved. The achievement adds to your collection and provides another fun Natlan memory.
