The Glacial Fortress is a Gummi Heartless that appears in Kingdom Hearts III. It can be found in Misty Stream, near Arendelle.
Design
The Glacial Fortress takes form of a large fortress, with some of its tower components composed of ice.
Strategy
In the beginning of the battle, the Glacial Fortress will have an ice barrier that surrounds the entire fortress, preventing the massive Heartless from taking any damages from the Gummi ship. The first order of business is to destroy the ice towers that surrounds the fortress, as the ice barrier is set up by them. The screen will pan around the fortress, giving the Gummi ship a chance to take down the ice towers surrounding the fortress.
