Petrichor Hydroculus Guide
This route takes you to collect all 3 Hydroculus in the town of Petrichor. Given there are only 3, this only takes around 1m.
Any character with exploration passives like Wanderer, Yelan, Sayu and Xianyun are suitable here.
Faded Castle Oculus
This route takes you to collect all 6 Hydroculus in the Faded Castle. This takes around 4m. Some of these do require Lost Grimoires which can be obtained by using the new gadget on floating books inside of the Faded Castle.
Tap the gadget to stun the book. Hold the gadget to open the door.
This underground map consists of multiple layers with Oculus on 3 different floors.
