◈'We Will Be Reunited' Archon Quest◈ 5 achievements (Total: 25 primogems)
After approaching the inverted Statue (halfway in the ruins), there will be a cutscene showing the collapsed bandit. The achievement will be issued after the cutscene.
After the cutscene with the inverted Statue, you will be told to flee the ruins. Continue through the rest of the ruins, and after the cutscene and fight with the Abyss Herald, the achievement will be issued upon leaving.
Ensure that you have a Healer or healing food as when you are near the inverted Statue, you will take damage periodically. Getting trapped in the bubbles will also cause damage when popped. You can use Geo Traveler/Zhongli/Albedo to create a construct to help glide above the bubbles.
You will have to look for traces of the Abyss Order in 3 separate locations. After defeating the enemies in the 3rd location, there will be a cutscene with Dainsleif about the Ruin Guards. After the cutscene ends, the achievement will be issued.
Although you will have several encounters with the Abyss Herald, this achievements refers to the 3rd fight (when you enter the ruins a second time).
Like with the 2nd fight, he can infuse himself with Hydro and his health won't deplete until you destroy that infusion (indicated by a blue bar). Equip your party with a Cryo character to freeze him as if you are hit by one of his attacks, your CD can be increased. There will also be a Hydro and Pyro Abyss Mage in this fight at the same time, so if possible, equip your party with a Hydro or Electro character too.
This achievement will be available after the cutscene with your sibling, which will be after the 3rd Abyss Herald fight.
