To initiate the first ruin exploration from the new Honkai Star Rail event, head to Boulder Town and talk to Balaway on the objective marker. He will brief you about the ancient ruin discovery at the Great Mine and further request that you assist Aksay, the senior treasure hunter.

Head to his location and interact to access the first Ruin. Your primary objective will be to press on the tile floors to unlock areas until you find the door cards. Follow the steps below to complete all eight levels of Surface Exploration:

• Level 1: Activate the tiles at the edges. The card should be located on the top right corner of the board, diagonally opposite the door.
• Level 2: Again, use the same strategy to access the bottom right corner tile for the Key Card.
• Level 3: The card is located on the topmost tile of the middle column.

In most cases, the Key Card will be blocked by an enemy. (Image via HoYoverse)

• Level 4: You should be able to see the key at the top-right corner of the board blocked by an enemy. Use the Ancient Bomb to clear them and collect them to proceed to the next level.
• Level 5: Again, clear the enemies on the path to collect the key, visible at the top row.
• Level 6: You will have to complete an elite encounter for this level, which will promptly unlock the surrounding tiles containing the door card, alongside a few other items.
• Level 7: Once again, the key should be on the diagonally opposite end of the starting point.
• Level 8: Defeat the Elite Enemy to unlock the teleporter.

Deep Exploration unlocks once you complete all the above levels. Now refer to the following list to complete the next stages of the Underground Treasure Hunt event in Honkai Star Rail 1.2:

• Level 1: Complete the encounters to proceed to the key card, located on the opposite end of the door.
• Level 2: You can find the card in the bottom left corner of the area.
• Level 3: Obtain the card from the tile under the "Hiring Treasure Hunter" marker.
• Level 4: Unlock the tiles in the extreme right columns of the box. The key should be on the topmost tile blocked by the enemies.
• Level 5: The key is located at the bottom left corner.
• Level 6: Once again fend off the Elite Enemy to access the teleporter.

Most of the enemies in the event will have Lightning Toughness, so deploy a team accordingly to tackle them. On that note, HoYoverse has provided Kafka and Luka as trial characters for the ruin. You can pair them with Tingyun and Luocha to tackle all the encounters.

Additionally, pick up all the Ancient Ruins and other collectibles to strengthen your entire team for the specific ruins.
