Hyrule Warriors/Lake Hylia (Linkle)

Continuing on her adventure, this timeline takes place after both Impa and Sheik that turns out to be Zelda closed the Gate of Souls. Volga takes the allied base and Darunia is determined to take him on. So it's pretty much the same thing in reverse. Instead of starting outside the Water Temple, you and Ruto will start inside the Water Temple.

Help the engineers!
You and Ruto will start at the south end of the temple. Eliminate as many Lizalfos in the temple as much as you can. Because the doors has been closed, protecting three goron engineers from danger can help speed up the process since time is not on their side.

Protect Darunia!
As soon as the doors were open by the goron engineers, command Ruto to protect Darunia while you take care of poes and lizalfos. Volga will also send two special lizalfos, making you do two jobs at the same time. At Darunia's side, take care of all the monster enemies attacking him and if his health is low with the green circle, go close to him and he'll health automatically.

Linkle on the other hand must take care of all the threats, including two special lizalfos. The bases will open so quickly take their base to minimize the flow of monsters coming out.

Darunia versus Volga?
Multitasking can be a difficult thing unless it's second nature to you. If you got everything like skulltullas, bases, checkpoint officers and any important officers you need to defeat, that's when you have to defeat Volga as long as Darunia and Ruto is alive as they were both important in dealing with any more officers left. It may the two fighting but with Ruto and Linkle, it's more like three to one fight.

Once it's over, Linkle will continue on her adventure, going the wrong way again. Don't worry though, she'll reach the castle very soon.
