Hyrule Warriors/Lake Hylia

Recapping the last event, Darunia followed the Zelda look alike orders. So they're going to Lake Hylia to where the source is with one problem: only Zoras can swim and battling underwater is very unlikely. Nor is there a supply of blue tunics at all.

Veterans should recognize not just the three level Water Temple (redesigned for the purpose of this game following in vein of the Dynasty/Samurai Warrior series) and the fishing area where you fish for the largest fish to get a prize. Anyway, Impa, Sheik and Darunia, leader of the Goron tribe is going to get to Evil Zelda and close the "Gate of Souls". As recommended, go with Sheik.

Saving Princess Ruto
Since she's the "key" to the Water Temple, you have to protect her from Lizalfos, poes and you have to take her to the base in order to drain the water down so you can access the Water Temple. As oppose to using your hookshot underwater to open the door in "Ocarina of Time".

Race around the temple
Princess Ruto will go to the middle to get the "Lens of Truth". Again, veterans already knows but what the "Lens of Truth" does briefly is to reveal what's "real" and what's not. It's put to great use at the "Bottom of the Well" and "Shadow Temple" at the Graveyard.

Back to reality, you need to not only just drain more water from the bottom corner of south east and west, but to save Darunia outside the entrance of the Water Temple. It will be more luckier if you're playing on the 3DS/Switch version, the ability to change between Sheik and Impa.

As soon as you finish draining the water by conquering two key bases on the south, go to the middle south to battle the gatekeeper to unlock the middle area. If Princess Ruto is in danger, you'll see a green circle. Race to the green circle so you can automatically heal the Zora to full strength.

Dodongo and Evil Zelda showdown!
If you think you're nearly finished, think again! Evil Zelda calls Dodongo back! Oh no! Looks like you have to fight it again?! So to keep it short, follow this pattern: as soon as Dodongo sucks the air in, throw in the bombs and attack its weak point (by the circle) for about two to three times.

The "Lens of Truth" should open the boss area located at the bottom south, though you'll find the door, south from the middle area. You'll have to battle hard since Lizalfos and Poes were there as well. Anyway, once you finish battling Evil Zelda, this should end this level.

The cutscene would reveal that Evil Zelda is actually Wizzrobe. And Sheik is actually Princess Zelda?! Anyway, they both magically close the portal and that ends the tour of "Ocarina of Time". So what happen to Lana and Link while ending this war? You'll have to play four more levels to find out: Two in "Twilight Princess" and two in "Skyward Sword".
