Source Material Collection guide in the Genshin Impact Core of the Apparatus event

Source Material Collection is the first part of the Core of the Apparatus event, and it involves collecting items to fill up The Great Machine. After speaking to Bertrand, he'll give you a Gadget called the Material Collector. It will fill up as you collect the materials that he asks you to acquire.

Bertrand will ask you to collect the following. Keep in mind that you must have the Material Collector equipped while playing through this segment, or the items you pick up won't register.

Three Ores

You can collect any three of these ores (duplicates are allowed!) to fulfill the event requirements.

Three Flowers

You can collect any three of these flowers (duplicates are allowed!) to fulfill the event requirements.

Six Fruits

You can collect any six of these fruits (duplicates are allowed!) to fulfill the event requirements.

Return to Bertrand to report your collection progress. Don't forget to head to the Source Material Collection section in the event menu to claim 60 Primogems and other rewards for completing the segment.
