Valid Intelligence Unit
The Valid Intelligence Unit is an event currency in Arknights.
Whether it's providing mission feedback, collecting spoils, analyzing materials, facilitating communications, or streamlining operations, Rhodes Island's efficient intelligence system continues to collect complex data from a vast array of actions and operations in order to provide the best course of action. For those unfamiliar to the mechanisms of this black box, just looking at the results will suffice.
Usage
These representation of Rhodes Island's SIGINT and HUMINT efforts are used during the Operational Intelligence event as a "milestone" for the purpose of handing out event rewards. Refer to the Operational Intelligence event article for more information about the rewards and the amount of Valid Intelligence Units needed.
How to obtain
Valid Intelligence Units are awarded by clearing any operation except Challenge Mode, Annihilation, and Extreme Mode operations during the Operational Intelligence event, with the amount being equal to the Sanity spent to run the said operation.
