●During this event, complete the quest “Life Flows On (I)” to obtain the event gadget Inquisitive Endora. Equip it to explore designated areas and use special skills to capture Oceanid Creatures and increase your exploration progress. Completing an exploration will reward you with a Heart of the Spring.
Going by mined information for Wishful Drops, you’ll be able to obtain a mini Oceanid (appearing to be called Endora) to accompany you in Genshin. There’ll be the usual Primogem rewards for the event besides the other rewards. We should be able to expect the exploration areas to unlock daily over the week, as is usually the case.
