Step 3: Turn around and walk ahead until players see a big Unique Rock Pillar. Like before, use a Geo character's skill to summon a Geo construct. Once it hits the pillar, a resonant quake will occur and remove the debris that is blocking the domain's entrance.

Vermillion Hereafter and Echoes of an Offering sets from The Lost Valley

The Lost Valley Domain features two new artifact sets: Vermillion Hereafter and Echoes of an Offering. Both sets have one character that can take full advantage of the set bonus.

View the Genshin Impact Beginner guide here.

Echoes of an Offering

• 2-piece set bonus: ATK +18%
• 4-piece set bonus: Wielders have a 36% chance to trigger Valley Rite, which will increase Normal Attack damage by 70% of their ATK. If Normal Attacks don't trigger valley Rite, the chances of it triggering in the next Normal Attack are increased by 20%

Vermillion Hereafter

• 2-piece set bonus: ATK +18%
• 4-piece set bonus: Wielder will gain a stack of Nascent Light effect once activating Elemental Burst, increasing their ATK by 8% for 16 seconds. When a character's health is reduced, their ATK increases by 10%. This can be stacked a total of four times

The Echoes of an Offering is Kamisato Ayato's signature artifact as his skill centered on his Normal Attack. Vermillion Hereafter, on the other hand, is beneficial for Xiao because his Elemental Burst automatically reduces his health every time making a Plunge Attack.
