Three platforms overlook the stage in an inverse fashion to Tower of Heaven; one on the bottom, and two at the top. Both the snow and the water in this stage are merely cosmetic, and as such Etalus must still generate ice to slide and gain armor.
Two chains pull up large solid ice barriers that can be destroyed by inflicting enough damage. After time, the ice barriers are pulled up again. Players can stand on top of the barriers.
- Frozen Fortress was one of four stages that were first released with the official launch of Rivals of Aether
- There is a statue of Etalus sleeping on the right side.
