Ice Prison

Ice Prison is a sub-clan with units exclusive to the Granblue clan. The units focus on sending rear-guards to the drop zone and superior calling cards from the drop zone, which causes the activation of some skills.

Who are the Ice Prison warriors?

They are the ones who inhabit the Ice Prison of the underworld. They were brought there to serve as the guardians by the Necromancer  to control the gates to and from the underworld. Now with control of the gate to hell, they bring back their enternal army from the graves and use it to vanquish their enemies on the seas.
