Purbiruni's Commandment Walkthrough

Search for the Purbiruni Scholar

Walk towards the entrance to the Akademiya and wait for Paimon to remind you about the Purbiruni Scholar. Then, head over to Iris' and Hawa's direction, and ask them about Khedive's whereabouts.

Search for Sadife

After hearing Iris out, search for Sadife further inside the Akademiya. You can see him standing by the bridge that connects directly to the House of Daena, just past the fountain in the main hall.

Find Sadife's Case

Once you've obtained Sadife's Marked Map, teleport to the Garden of Endless Pillars domain, northwest of The Dune of Carouses in the Sumeru Desert. Then, use the nearby Four-Leaf Sigils to easily reach the small plateau in front of the domain!

Defeat the Treasure Hoarders

There are three digging sites you must check to locate Sadife's case. Checking the one in the left spawns Scorpions, while the one across you spawns nothing. Approaching the one to your right spawns Treasure Hoarder enemies so defeat them, and have them return Sadife's case to you!

Report Back to Sadife

Return to Sumeru City, and report back to Sadife. After telling you briefly about the Purbiruni's research principle, teleport to The Chasm, and report back to Khedive.
