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 Phase 2 of the 4.0 Banner schedule we have returning Geo 5-Star Zhongli's Gentry of Hermitage Banner and returning Hydro 5-Star Tartaglia (Childe)'s Farewell of Snezhnaya Banner. New Cryo 4-Star Freminet is also featured as one of the boosted 4-Stars on both Zhongli and Childe's Banners.
These Phase 2 Banners are expected to run from Wednesday 6th September until they end on Tuesday 26th September - the day before the expected release date of version 4.1.

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.

The rewards you can earn from the Mega Meka Melee event event include:
- Free Bennett character

Verdict of Blades event
Verdict of Blades is a combat challenge where you have to use the Blade Mirage mechanism to gain an advantage in fighting, and there are also various difficulties you can play the challenges on. It sounds like a pretty standard Genshin combat event.

Hope you have fun exploring Fontaine in 4.0!
