The Shadow Over Petrichor Walkthrough

Defeat the “bandits”

As you trigger the cutscene, the gang of rogue adventurers becomes suspicious of Traveler and Paimon. Quickly take care of them through combat!

Examine the chest carrying the treasure

After the quick skirmish, a cutscene plays as Paimon and the Traveler wonder what the bandits were talking about.

The treasure may look like a bunch of shattered stones but as the Traveler inspects it, it suddenly holds memories of a distant past.

Head to Petrichor

After Paimon's worry for the sudden trance, the pair decides to head to the nearby town of Pertrichor to look for answers.

After some exchange with the locals, Este is interested by a local cat's pendant. However, the cat immediately runs off.

Explore the ruins in the mountain

Este suggests that the cat might have ran to the nearby ruins. Head over around the nearby hill to reach the mysterious ruin.

Defeat the revived statue

As soon as you arrived, the nearby statue revives itself and presents a challenge to the Traveler. This Praetorian Golem has quite a health bar, so make sure to be ready!

Talk to the talking cat

After your impressive showcase of combat skills, the cat you were initally chasing after shows that it is not just another regular cat. It introduces itself as Osse, and is familiar with the ruins.

Follow Osse into the deep spring

Osse quickly jumps into the nearby edge. Follow them and jump over to the underwater area to explore a new region.

Go to the underwater Faded Castle

In this stage, Osse guides us around underwater. Simply swim around the new area to follow Osse.

Head to the Faded Castle

As you follow Osse, you should be able to see the mysterious ruins underneath Petrichor. You should be able to reach a walkable area which resembles an old, faded castle once you follow Osse.

Obtain the Autoharmonic Music Box

Once you explore the Faded Castle, Osse presents an old mystical music box which Osse suggests will be useful later!

Obtain music scores

The brief exchange ends the quest. However, with the music box unlocked, Travelers can search the castle for other scores. These scores can give you various rewards once you present it in the music box!
