Surface and Deep Exploration Process

Start the Unlock Mission

Honkai Star Rail - Balaway Location

To start the event, talk to Balaway who has discovered new ruins within the Great Mine and he will lead you to the senior treasure hunter, Aksay to be his exploration assistant! There will be a mission each day to unlock a new stage within the Underground Treasure Hunt.

Two Exploration Types

Honkai Star Rail - Exploration Types

Within a stage, there are two types of ruin exploration: Surface Exploration with easier enemies and Deep Exploration which raises the difficulty. Additionally, you won't recover Stamina when you reach a new floor in Deep Exploration.

Surface Exploration has 8 levels while Deep Exploration has 6. Note that you can only unlock the Deep Exploration after completing the Surface Exploration!

Talk to Aksay to Enter the Ruins

Honkai Star Rail - Ruin Details

Once you've completed all prerequisites to join Aksay, talk to him to enter the ruins. Before actually entering the ruins, a screen will pop out that shows the ruin details, inherited ruin stats, and upcoming enemies. The screen also has the edit team section.

Use a Team Suited for the Enemies

Honkai Star Rail - Ruin Trial Characters

You must have team members before you can enter the ruin. The possible enemies will be shown on the initial screen, so you can choose team members that can work against them! You can also use trial characters if you don't have the right characters built.

Press on the Highlighted Tiles

Plan a Route to Manage Stamina

Honkai Star Rail - Find Provision Supplies to Recover Stamina

Pressing on the tiles will consume stamina. There's a limit to the amount of stamina that you have. So, you must plan out your route to conserve it as much as possible. You can also obtain provision supplies that can recover your stamina.

Note that if you run out of stamina, exploring will consume your entire team's HP. This will render them vulnerable against enemies you may encounter within the mine!

Find Ancient Equipment for Boosts

While exploring the area, you can get ancient equipment that can boost your team's stats or even defeat enemies within an area!

Use Ancient Relics for Buffs

You can also find enemies within the ruins, these enemies can block a path or even enhance other enemies within the level! Defeat the ones you need to make exploring easier. On the last level, you must defeat all enemies to exit the stage!

Get Help From Extra Characters

Honkai Star Rail - Encounter Random Trial Characters

Within the ruins, you can encounter additional trial characters that you can add to your team! Make use of them when facing enemies with weaknesses you don't have covered.
