After Floors 10, 30, 50, 70 and 90 you will be able to access the Fire path, the Ice path, and the Electric path. When starting the dungeon, you'll take the Steel path. On Floor 20, you take on the Fairy path, the Dragon path on Floor 40, the Dark path on Floor 60, and the Poison Path on Floor 80.

Dungeon Objective
The main objective is obtaining the Fire, Ice, and Electric Orbs to access Sky Garden, and to beat the dungeon generally, as its missions currently give the most Explorer Points, so getting access to these is a priority for players. The Sky Garden's end boxes can contain a Miracle Chest or Golden Mask as well, which are often highly sought after items. Being a late game dungeon, Sky Fortress gives high experience so players additionally come to train. Other motives are collecting Unown or any of the dungeon's exclusive Pokémon or getting the Heart Slates of Articuno, Zapdos, Moltres, or Rayquaza for use in a Mystery Part.
