Base
Last updated 2026-03-27
In Honkai Impact 3rd, the Base refers to the entirety of the Battleship Hyperion of which players are the Captain. It is a flying mobile fortress designed to help develop the strengths of the Valkyries and house them until they are needed to be deployed on missions. The Base houses many facilities that can help strengthen Valkyries, allow for adventures to help gather materials and 
Coins, or even allow Captains to make more friends.
The Base was overhauled in Version 3.5 and merged into the Dorm.
Honkai Powercore
The Honkai Powercore powers the ship, Hyperion, and enables the usage of buff modules within the various facilities located on the ship. The Honkai Powercore has a limit, however, and must be upgraded to gain more EP so that the Hyperion can power more buff modules. The Honkai Powercore is recommended to be upgraded as soon as you hit the limit.
Hub
The Hub controls the amount of friends a Captain can register. Captains can add 2 more friends for every module unlocked for every module unlocked. It is recommended only to upgrade the Hub when you wish to increase your friends list capacity.
Refinery
The Refinery collects and produces Coins and materials over time. Collecting Coins from the Refinery is often a necessary task in dailies and event missions. By upgrading the Refinery, Captains can add more slots for the Refinery to hold additional materials and allow for the gathering of higher rarity materials. Most of these materials, however, are obtained rather easily in other ways, so it is not recommended to upgrade the Refinery unless there are no there options to upgrade. At level 38, the Refinery will begin to have a chance to collect Advanced Evolution materials such as 
Tesla Turbines, 
Super Alloy Shields, and 
Phase Shifters.
Command Center
Base Adventure
Starting at Captain Level 35, the Command Center allows Valkyries to be deployed on "Adventures". Deployment on Adventures does not preclude the use of Valkyries elsewhere. Adventures rank from C to SSS. Higher level Adventures have rarer possible drops and higher corresponding drop rates. Higher level Adventures may be unlocked by leveling Command Center and activating the relevant Buff Modules. For example, level 22 Command Center allows for the activation of Buff Module "Unlock Adventure - Level 50 Difficulty S", which in turn unlocks S rank Adventures. S rank or higher Adventures may drop Advanced Evolution Materials (ie. Tesla Turbines, Super Alloy Shields, and Phase Shifters). However, at level 22, the drop rate per Adventure is relatively low.
Adventures have a refresh timer. When the refresh timer expires, all existing Adventures are replaced with new ones. Everyday, Adventures completed the previous day will also be replaced. An Adventure may require two or more Valkyries, specific Valkyries, or specific types of battlesuits. Some Adventures require 
Stamina and those that do award a proportional amount of 
EXP. The length of time an Adventure takes is determined by its rank.
Expedition
The Command Center allows Valkyries to be deployed on "Expeditions", which is an automatic way to grind story chapter stages that drops Valkyrie fragments or rare materials. An Expedition always requires three Valkyries and there is a CP requirement for each Valkyrie, determined by the difficulty level of the stage, starting at 700 CP. Expeditions and regular battle share the same allowance per stage per day as well as the same 'pity drop' counter. The total amount of Stamina a Captain can spend on Expedition is limited by the Captain's level. The duration of Expedition is determined by the difficulty of the stage and starts at one hour.
An Expedition can be completed by a Valkyrie and her awaken form simultaneously. However, if a Valkyrie is on Expedition, her awaken form can not be sent out on any additional Expedition. (This may be important for new players trying to complete as many Expeditions as possible at a time.)
