Grey HiSec Key

Grey HiSec Key
The Grey HiSec Key is a GP item which is available from the shop for 1900 GP. The item is used to open Grey HiSec Cases. Not surprisingly, the Grey HiSec key is much more popular than the Black HiSec Key even though more Black HiSec Cases are dropped. This is because most players are not Black Market Users and therefore cannot buy anything using NX.
