Echoing Tales is an event coming with the next major Genshin Impact version update, and details have been released through official social channels: Twitter here. Players will need to be Adventure Rank 21 and above to get started, with the event itself available until the end of version 1.6 (presumably 19 July).
The details are simple: the Genshin version update will open up new islands, and Echoing Tales requires you to collect “Echoing Conches” scattered throughout them. You will need 24 Echoing Conches to obtain Barbara’s Outfit, Summertime Sparkle, for free. Otherwise, it will be available through the Character Outfit Shop at the end of version 1.6 at 1,680 Genesis Crystals.
Event rewards include a total of 240 Primogems, alongside Talent Books, Mora, Mystic Enhancement Ore and Hero’s Wit. The islands will no longer be accessible at the end of version 1.6, meaning no more Echoing Conches you can collect – besides the treasure chests, quest rewards and more across the islands.
This one’s more of a side event to the main four act event, Midsummer Adventures, which also revealed its relevant gameplay details you can check out here. Be sure to not miss out on all the exploration, and the event rewards of course!
