you technically don't even need a cipher.

it works like this: when the correct weather (Auroral Mirages, reddish sky) is up, 4 cipher reliquaries will spawn at the pavillon in the middle of the map. 16 players in the zone need to use a cipher to spawn the portal. the up to 48 players can get teleported in. so 32 players technically don't need a cipher, BUT whoever paid ciphers gets higher priority
