Lost Valley Domain Location

How to Get to the Chasm Domain

Location	Fuao Vale, The Chasm

The Lost Valley Domain is located in the Fuao Vale area of The Chasm. Go a bit south of the domain marker and look for a Unique Rock with a Geo logo on it.

Locked by a Unique Rock Pillar Puzzle

You need to place a Geo construct on the circular plate near the cave, rush to the large, glowing rock nearby, and hit that glowing rock to send out Resonant Quakes. The Geo construct will let the quakes reach the cave blockage and clear it.

Tips for Beating The Lost Valley

Bring good support characters

You're up against a heavy-hitting Ruin Grader, so we recommend bringing good shield and healing characters! If your Zhongli's shields are top-tier, you can even skip out on bringing a healer.

Use your Elemental Skill as often as you can

Each time you use an Elemental Skill in The Lost Valley you deal a shockwave of damage to enemies. Using characters with quick Elemental Skill cooldowns will let you spam the shockwave!

Although this is a great help for speeding through the Domain level, we still recommend you bring your best characters even if their Element Skill cooldowns are long.
