Genshin Impact 4.0 Banners

The version 4.0 Banners debut 5-Star Lyney, and 4-Stars Lynette and Freminet across two Banner phases.

Phase 1 of the 4.0 Banner schedule begins with new Pyro 5-Star Lyney, featured in his Conjuring Chiaroscuro Banner, and returning Hydro 5-Star Yelan featured in her Discerner of Enigmas Banner. Anemo 4-Star Lynette is also featured as one of the boosted 4-Stars on both Lyney and Yelan's Banners.

It's worth keeping in mind for your Wishing plans that Lynette is rewarded for free when you reach Adventure Rank 25.

As usual, the 4.0 Phase 1 Banners will run alongside each other, and should be available from Wednesday 16th August, until they end on Wednesday 6th September.

In addition to this content, we're getting the usual four events during the 4.0 update to Genshin Impact.

Here's everything we know about every time-limited event in Genshin Impact 4.0:

Mega Meka Melee event

For the Mega Meka Melee event the Traveler needs to assist a Fontaine shop owner with some experiments. Additionally, there is an event storyline for Mega Meka Melee called 'Toy War Situation Map' where you explore Bennett's connections to the shop.

The first Mega Meka Melee task is called Torrential Turbulent Charge, which is an underwater challenge where you need to touch Turbulent items to take part in a race to the finish line.

The second challenge, Efficacy Testing Simulation Area, is a combat task where you have to fight different types of enemies, including the new Clockwork Meka varieties.

The third and final challenge, Dance Dance Resolution, is a musical task, but it looks a little different than previous music-based challenges. Here, you take control of a 'Toy Adventurer' and attack at the right moment, matching up with the beat of the music.

Relic Records - Creations of the Hydro Nation event

This seems like a standard item and enemy location event, where you have to explore specific areas to find the targets marked in your Relic Records. It looks like a good way to get rewarded for collecting Fontaine intel that will be handy to know in the long run.
