Skulltula: Defeat 1,000 enemies
Fight a few enemies and wait for your objective to be updated. Head to the Statue Keep to find Fi. You need to protect her since she carries the vital "soup" needed by Levias. Escort her until she successfully delivers it. Levias will push a large chunk of floating rock and connect the paths.
Note: Be careful not to destroy the boulder outside the statue base. This is where the Golden Skulltula is located. Destroying it before you kill 1,000 enemies will prevent it from spawning.
Enemy forces will be attacking the allied base so quickly eliminate the enemy forces around the statue and head back to stop them. You'll also encounter the enemy commander named Ghirahim. He doesn't attack that aggressively but when he starts his combo, make sure you evade and counterattack. He doesn't reveal his Weak Point Gauge that often but you should be able to chip away his hp with continuous attacks. Once you drive him off the battlefield, keep defeating enemies and capture the nearby outposts and bases around the allied base.
While doing this, remember that you still need to keep an eye on Fi and escort her. The Academy Keep needs to be captured but it is guarded by three Aeralfos. Take them out and the Keep Boss. Next, follow Fi as she makes her way to the southwest. There will be a Deku Baba guarding the path. Destroy it using your bow to proceed.
Capture the West Town Keep and Fi will continue north. After successfully delivering the soup, Levias will connect yet another path. You can now head and take over the remaining enemy bases. However, Volga will apear and the objective will be updated. To win the scenario, you have to deal with him. Before doing that, make sure to capture the N. Rockface Keep; there's a heart piece that will appear in the middle of the keep after capturing it.
Fi will be engaging Volga so its possible for you to make some quick trips to kill large enemies for their Materials. However, take note that if Fi gets defeated, your mission will be over. Keep fighting Volga until you critically damage him. His dragon form is quite annoying and threatening. After enough damage was dealt, he will power up which will make it difficult for you to defeat him. You have to make your way to the Fairy Fountain to ask for the Fairy's help.
A couple of aeralfos and their goblin troops will appear outside the entrance of the fountain. Defeat them then use the magic circle inside to weaken Volga. Once done, intercept him and fight him. Volga's fast but his attacks can be pretty predictable. Once you see him blocking your attacks consecutively, prepare to evade. He won't be using his dragon-form that much after being struck by Levias' lightning so you just have to anticipate his spear attacks and his slow, fire-breathing attack. His weakness gauge only appears briefly so you have to memorize his attack patterns and make the appropriate countermeasures as necessary.
After the battle, Fi will become a playable character.
