How to defeat Marana's Avatar in For All Children Who Long for Life Sumeru World Quest in Genshin Impact
In this World Quest, you will be controlling the Dendro Traveler at level 80 with preset stats, Constellations, and Artifacts. Start by following Arama toward the clearing with Marana's Avatar. After that, follow Arama once again toward the first Withering Zone. Arama acts as a healer, so approach him when your HP is getting low. Pay attention to the Decay meter above your HP bar as well, and make sure to approach Candles of Life to prevent dying.
Since you have no archer in the team, interact with the Sprouting Branches to summon Healthy Dendrograna, and then attack the Withering Branches using a Charged Attack. After getting rid of all Withering Branches in the area, defeat the enemies and destroy the Tumor of the Withering. You'll then be prompted to return to Marana's Avatar. You can use the Four-Leaf Sigils to head to the battle area.
Marana's Avatar has to be defeated in phases. Once its HP drops to a certain level, Arama will ask you to follow him to the next Withering Zone. You need to alternate between getting rid of Withering Zones and attacking Marana's Avatar two more times before its HP will be low enough to prompt a cutscene, after which you'll be able to completely destroy Marana's Avatar.
After defeating Marana's Avatar, a series of cutscenes and dialogue will commence. Once they're done, equip the Vintage Lyre and play the Rhythm of the Great Dream (fa > mi > so > fa > do on the first line) beside Arana to complete the World Quest.
