Okay, few questions really fast
1. How do you actually unlock Destiny Tower? Is it getting all of the Treasures and then getting all of the Legendaries? I don't necessarily understand the 'Globes' that Torkoal is talking about
2. Do you need to actually clear the dungeons where just get the minor Type treasures (like Treacherous Waters, etc)
And 3. Assuming that Revival Mountain is Ho-Oh how do I unlock that? I thought it would be like Lugia where you just need the Kanto trio but it hasn't popped up
