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 items almost always wanted. 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 the Mystery Part.
