The Clearance Permit is an event currency in Arknights.


A customs certificate stamped with proof of border crossings from all over. Can be used to exchange for supplies at the Trading Station. Don't ask what purpose they have for taking these.

Used to prove the holder's legitimate entry credentials, as well as grant temporary right to remain. Absolutely essential when entering or exiting large nomadic cities. Some places don't check too thoroughly, but it's still best to have your papers on you.


These permits used as clearance through the strict bureauracy of Leithanien Customs can be obtained and exchanged for various items at the Local Office during the Preluding Lights event.


Clearance Permits are awarded by clearing any operation except Challenge Mode, Annihilation, and Inferno Mode operations during the Preluding Lights event, with the amount being equal to the Sanity.png Sanity spent to run the said operation.
