To complete the Lunar Awakening Event Questline in Diablo 4, follow these steps:

1. Earn Ancestor's Favor
The key to progressing through the event and unlocking rewards is to earn Ancestor's Favor. You can gain favor by Diablo 4 Items participating in the Lunar Shrines that appear on the map.
Lunar Shrines are marked with a purple star icon on the mini-map. These shrines activate when you approach them, allowing you to start the event.
2. Interact with Lunar Shrines
Lunar Shrines come in different forms, representing the animals of the Lunar Cycle (such as the Rabbit, Dragon, Snake, etc.).
When you activate a shrine, you'll enter a zone where you can kill enemies to cheap Diablo IV Items collect Ancestor's Favor. This is the main mechanic for earning progress in the event.
