Hyrule Warriors/Valley of Seers (Ganondorf)

Excluding side character levels, this is your third visit but this time as Ganondorf. Since Lana has the Triforce of Power, he will go to no end to get it but has to deal with many challenges just to get it.

Ganondorf to the rescue
Even though it's hard to know if he's compassionate, this objective shows: Girahim will be trapped on the south west base while Zant will be trapped on the north western base. But fortunately, there's a way to get them in time: if the north part of both bases were open, then think like a maze; just skip through the enemies until you reach either of them. On the 3DS and Switch, you can choose to play either of them once they've been rescued.

Impa seven trouble
Things will get harder now that Impa came. She'll create so many doubles, it's hard to tell which one is the real Impa. Depending on which version your playing, even in co-op, eliminate all the Impas since they'll cause you trouble. Even at your Allied Base.

Showdown with Lana
Before facing Lana, make sure you take care of checkpoint officers and take all bases to avoid dealing with endless enemies coming out. Most importantly, get Girahim and Zant waiting by the Fairy Fountain in the middle. You'll find out why as there always another surprise behind this. Anyway, go to the middle north where the enemy base is. Defeat Lana as much as you can but as soon as you finish, run to the Fairy Fountain and here's why you have to do that?

Triple Lana Trouble
Impa has prepared three magic circles for three Lanas to escape! Don't panic! Girahim and Zant should automatically chase one of them. If you manage to get there earlier enough, you should be able to attack at least two to three Lanas while the third one is slowly escaping. It's a matter of time so attack two quickly and run to the third and attack before the last Lana escape! It might take many tries at first but it's worth the challenge: seeing Ganondorf running for vengeance!
