Altered Mt. Zodiac
Altered Mt. Zodiac is DLC content that is part of the "Chaos Omnia Impera" DLC, accessible through a portal at Mt. Zodiac. It also contains the Event Horizon sub-area. Its eight numbered zones each feature a Furious Battle against a Genie-type legendary (Thundurus, Enamorus, Tornadus, Landorus) plus an X-Species Tapu (Tapu Fini X, Tapu Lele X, Tapu Koko X, Tapu Bulu X), and a dedicated "Donanas Zone."
How to Reach It
Accessible through a portal at Mt. Zodiac. After completing it once, returning to Hadwarf City and talking to Aster grants the Reveal Glass, which can then be used at a hole in the wall near Mt. Zodiac's entrance to return to a harder version of Altered Mt. Zodiac ("A free being" / Hard Mode) versus the initial "A fettered being" / Normal Mode.
