Your Base: What is it? An Introduction

First off, if you're reading this guide, I assume that you have reached captain level 23, the minimum required to enter your base, and you don't really know what does what.

To access your base, you need to tap on the base button from the main menu. It will then bring you to something that approximates the screen below. Also, if you've been playing on an emulator the entire time, the base screen responds to motion controls and tilts as you move your phone, like the main menu. It's pretty cool. You should check it out.

Here is a picture of my base. You can see each of the buildings clearly labelled, with their level next to it. If any buildings are currently being levelled up, a progress bar, along with the time to completion, will be shown underneath the name. There are four unique buildings: the Hub, Refinery, Honkai Powercore, and Command Center. The other four, the Shooting Range, Commander Training Room, Dojo, and Mecha Training Room, are stat enhancement buildings that correspond to one of the Valkyrie characters in the game. When Teresa is released, she will have her own enhancement building. (This guide was written in earlier ages of Honkai Impact 3rd)

Clicking on any building will bring up a screen similar to the one below. If you forget the functions of a building, you can see a short description of what it does after selecting it, as well as its current and maximum level.

From here, you can either level up your building to unlock more features and make the building more powerful, expand it to increase the level cap, or enter the building to actually access the functions of the building.


Base Actions: Level Up, Expand, Activate Buff Modules

These three actions are shared between all buildings (except the Powercore, which has no buff modules). To level up a structure, click on the level up button in the bottom right corner. After doing so, a dialogue box will pop up showing the required items and coins to perform the action, as well as the time needed. While one building is being upgraded, you cannot upgrade another one, so if you don't want to wait, you can instantly complete the upgrade by paying a small number of crystals depending on the time left till completion.

Here is the dialogue box showing the Shooting Range going from level 5 to level 6. In doing so, it tells me that another buff module will be made available after levelling up. Different buildings have different times required to level up, and the time increases with each level added. The Refinery is the quickest, followed by the Hub, the four stat enhancement buildings, the Powercore, and finally the Command Center is the slowest.

Once you have maxed out your level of the building, you cannot level it up again without expanding it. Expansion requires the building to be max level, and increases the level cap of the building.

Expansion is completed instantly, but be aware that after expanding, to level up the building again requires upgrade materials of the next tier.

Each building also has buff modules you can activate, provided the building is high enough level. To access these modules, first enter the building, and then click on the increase button on the right side, circled in red. Remember, unlike other buildings, the Powercore has no buff modules.

To activate a buff module, click on the inactive and unlocked module you would like to activate.

The effects of the module will then be displayed, as well as the EP required. Then, click the "Activate" button. You must have free EP at least equal to the required EP of the module to activate it. Also, you need to have activated at least one of the modules next to the one you want to activate. Each building has unique buff modules that will be explained in depth later, when talking about that building. If you find that you don't like the amount of EP one of your buildings is taking up, you can reset all the activated buff modules for a small fee of coins by clicking the reset button in the bottom right corner.


The Structures: The Honkai Powercore

The hub increases the maximum friends and skill points you can have at any one time. Entering the Hub will show you how many of each you have, as well as the bonus to your maximum. To increase these, just levelling up the building isn't enough. You need to activate the buff module associated with either maximum friends, or maximum skill points.


The Hub

The hub increases the maximum friends and skill points you can have at any one time. Entering the Hub will show you how many of each you have, as well as the bonus to your maximum. To increase these, just levelling up the building isn't enough. You need to activate the buff module associated with either maximum friends, or maximum skill points.

The earlier modules only add +1 or +2, but that number increases as you level it up and activate the later modules. In addition, the modules that add to the number of friends do not consume EP, so if you want a large friend list, don't worry. You won't have to sacrifice your other buildings' efficiency for it.


The Refinery

The Refinery passively collects coins even when not logged in, which you can claim at any time by clicking the claim button.

While levelling the building will increase the coins per hour and maximum held, you can also increase them by activating buff modules, as well as increase the critical rate and multiplier.

Starting at level 7, you can also activate buff modules that allow you to collect upgrade and experience materials. One of the modules that allows you to do it is circled above.


The Stat Enhancement Buildings

For brevity's sake, I will only be showing the Dojo. The rest of them are functionally identical, except they correspond to different characters.

Like the Hub, levelling up the Dojo (or any of the others) does nothing on its own. You need to activate buff modules for there to be any effect.

Each of the buff modules increases a stat by 5% of its base value. In addition to requiring a certain level, there are also buff modules that require you to own a specific Valkyrie frame at a high enough level.


The Command Center

And finally, the last building, and the most complex. The Command Center allows you to send your Valkyries out on adventures to gain materials and coins. At first you are allowed only one ongoing adventure at a time, but this can be increased by buff modules. Be aware that if the Valkyries are sent off on adventures, they cannot be brought into normal missions. They can, however, still be used for Sakura Samsara, Infinity Abyss, and Matrix Exploration.

Entering the Command Center gives an overview of the available adventures, as well as the ones currently in progress. To start an adventure, just click the "Go!" button to go to the team formation screen.

Different adventures have different requirements and rewards. All requirements must be met in order to go on the adventure. If your team does not satisfy any, the requirement will be in red. For example, my Valkyrie Bladestrike is level 10 or above, but it is a Creature-type, whereas the adventure requires a Mecha-type character.

Once the team is sent out, the adventure will be listed as ongoing at the top of the adventure list. If you wish to use the Valkyrie that you have sent out, you may use Speed Order items to decrease the time required to finish the adventure, or click the “Retreat” button and withdraw the team. Nothing bad happens if you retreat; you just don’t get the rewards for completing an adventure.

Once an adventure is complete, you may claim the rewards, and the adventure disappears from the list of available adventures. Adventures refresh every day at midnight, and you can manually refresh by paying a small fee of crystals.

Sometimes, in addition to the materials in the drop list, your Valkyries will bring back more coins or experience materials. Other times…

Please do not overwork your Valkyries.

There are three different types of buff modules available for the Command center. One increases the difficulty cap of the adventures that show up, one allows more adventures to show up when they are reset for the day at night, and one increases the number of adventures you can have active at once.

There are also adventures that require stamina. These will show up at the bottom of the adventure list, and each one rewards captain EXP in equal to the stamina consumed in addition to the material drops.


What buildings should I upgrade first?

Personally, I believe that the best building to upgrade is the Command Center, unless you do not have enough EP to activate the next buff module, in which case you should upgrade the Powercore. Sending your Valkyries on adventures gives a steady income of upgrade materials, which are required to upgrade other buildings. If you are starting out, well, first of all the Shooting Range is locked until captain level 33, and that's the earliest of the stat enhancement buildings. They also only upgrade base stats, which are not very high at lower levels. It is important to level them up eventually, but only for late game content. Unless you are a social butterfly, the base number of friends should be sufficient to not require upgrading the Hub. And the Refinery is not really worth the time investment compared to the rewards that adventures give.


tl;dr: Command Center = Powercore >>> Stat Enhancements > Refinery >> Hub.

Do adventures. Get matterials.
