Genshin Impact 3.6 is a huge update: more of Sumeru to explore, new artifacts, a free Faruzan, plus Baizhu and Kaveh

Genshin Impact 3.6 is out April 12 – technically late on April 11 for Western players – and it looks like one of the biggest updates of the ongoing Sumeru arc. 

The headliner is a new chunk of Sumeru to explore, just in case you thought this region couldn't get any bigger (say a prayer for mobile players). Split between oases and wastelands, this new area was once a battleground in the Khaenri'ahn war that's been looming over Genshin lore. It's home to a new weekly boss, Apep, the Dragon of Verdure, and we'll also encounter Anemo and Hydro Hilichurls as well as a new world boss.

We'll need those boss materials to level up Baizhu and Kaveh, respectively the new five-star and four-star characters of the patch. Baizhu will debut in the second half of the banner alongside a rerun for Ganyu, and Baizhu will be one of the four-stars on their banners. The first half of the update will see reruns for Nahida, who comes in at the top of our Genshin Impact tier list, and Bloom specialist Nilou.

Baizhu is a Dendro catalyst healer who can create temporary shields using his elemental burst. These shields appear periodically along with a burst of healing, and they'll buff certain Dendro reactions on top of giving you some defense. Kaveh is a Dendro claymore user who can infuse his sweeping normal attacks, while his skill and burst buff and expedite dendro core explosions, sort of like Nilou. 

Strangely, the new artifacts in this update don't seem to synergize with Baizhu or Kaveh much at all. The Nymph's Dream set boosts Hydro damage on its two-piece, with the four-piece providing additional Hydro damage and attack bonuses when you land different types of attacks (normal, charged, etc.). Vourukasha's Glow, meanwhile, feels tailor-made
