Imprisonment Array.
As the name implies, Scatter Immortals and those below who enter this formation can enter, but not exit.
This is because the Imprisonment Array differs from other formations: while most are primarily for slaying, setting one up equates to setting a Slaying Formation. Once inside, one faces myriad deadly calamities, with a slim chance of survival.
Whereas a Defensive formation is primarily for defense; no matter how many Divine Skills you possess, breaking through is almost unthinkable.
The Imprisonment Array is a rare type of Imprisonment Formation. In essence, it employs Formation Runes to fix and divide a separate space. Once trapped within this formation, one is lost in chaos, and escaping becomes exceedingly difficult. It is very possible to be imprisoned for a lifetime.
