The Legend of Zelda: Skyward Sword Cheats

Amber Relic - Found almost anywhere. They are found very common in the Faron Region. You only need 20 of these for all the upgrades. (Eh... meh. Who cares about this thing.)

Ancient Flower - They can only be found in the Lanayru Region. They can only be collected if you trigger the Timeshift Stones. You only need 8 of these for all the upgrades. This includes fixing Scrapper that Lanayru Robot, which only 1 is required. (Pretty flower.)

Bird Feather - The birds can be found only in the Faron Region and you are required using the Bug Net (or the Big Bug Net). You will need to walk carefully towards them and snatch them if you are close enough. The Big Bug Net is highly recommended since it is in fact larger and easy to catch both bugs and birds. You only need 5 of these for all the upgrades. (Boring feathers.)

Blue Bird Feather - Same as the Bird Feather in the Faron Region, but the only thing is that the blue birds are quite rare. If you happen to see one, don't just run after them. Do the same method for the Bird Feather and you'll harvest some Blue Bird Feathers. You only need 5 of these for all the upgrades. (Blue as the sky!)

Dusk Relic - Like Amber Relic, but are in different color. These things can be found almost only in the Silent Realms. So be sure to take a peek at every corner while you are in the Silent Realm. Be sure to pick up many of them as possible. You only need 13 of these for all the upgrades. (Ooh... mysteriously pretty.)

Edit: If you are in the Silent Realm, the best way to harvest as many of them as possible is to get hit by the Guardians and start all over again. You will notice that the Dusk Relics you found will re-appear in the same location. This will reduce your time of harvesting, but you will still need to complete the trail in the Silent Realm. But either way, it's all about patience.

Eldin Ore - Found in the Eldin Region mostly. They are commonly found by digging those digging spots and treasure chests in dungeons. You only need 6 of these for all the upgrades. (These rocks or metals are boring.)

Evil Crystal - These things are hard to come by, but they can be harvested from Cursed Bokoblins in the fourth dungeon. But as long you have the Treasure Medal, it makes harvesting a lot easier. You only need 3 of these for all the upgrades. (They... don't look like crystals to me.)

Edit: If you recall the time where those Cursed Bokoblins were about to get you on the lone rope and there's an escape route above,... 

Alright, there are some of you who have troubles with catching these blue birds in the Faron Region. Well, they can be found just about anywhere (which includes the last room of the first dungeon, but not the other dungeon in the Faron Region). First of all, you are being required the Big Bug Net. If you don't have it or the Bug Net itself, then you will never able to harvest as many Blue Feathers.

Now then, if you see a group of 3-5 birds (which these numbers do not always have the blue bird), then all you have to do is give them a distance, take your bug net out, and walk VERY slowly towards them. Make sure your net is facing where you are able to catch the birds. If you think you are close enough and ready to catch, swing the remote and you may catch at least 1 or 2 of these birds. Remember, it takes a lot of patience and a lot of steadiness.

If you did this right, then you can farm more of these Blue Feathers and you don't have to worry about looking for treasure chests for Blue Feathers. I hope this helps for those who enjoy this game.

If you have the item called "The Beetle", then go to Skyloft, pull out your Beetle, shoot it, and crash into people. You'll see a funny look on their faces. This was not first discovered by me, but really, it's hilarious. You can even do this to Pipit who's patrolling at night. :P

Alright, you must have experienced Shield Bash and Jumping Back Flips. Why? Because this is how I've done it to the Demise.

Phase 1 - You and the Demise are going to sword fight. So, all you need to do is slash a few times and wait for the Demise to slash at you twice. If he is, then use Shield Bash twice without resting. Once he drops his guard, slash away! Repeat this until you reach to the second phase.

Phase 2 - Now this part of the fight is very tricky. You don't want to use Shield Bash here or you will miss your chance of doing a Lightning Skyward Strike. So, you will execute the Skyward Strike by holding your Wii Remote pointing upwards. But the Demise will chase you and will strike you almost immediately. So you will want to perform a Jumping Back Flip when he is about to strike you. If you done this without being harmed, now is your chance to use the Lightning Skyward Strike at the Demise and slash away! However, even if the Demise is down, he's not weak enough. So you need to knock him down about three times and then perform a Fatal Blow.

Congratulations. You have defeated the Demise and brought back peace to... um... people of Skyloft and the surface world.

The first time you face The Imprisoned may seem frightening to you, but really, there's nothing to be afraid of. Anyways, the easier method is to go to the hole where it shoots out strong gust of wind. Once you are just about a platform higher than The Imprisoned, jump on over to his head and press the B button to safely land on its head. You will now have the advantage and vertically slash the stone on its head. You can do it about 2-3 times in the first round.

This method does work for round 2 and 3, but on the third round, you won't able to use the method I explained, so you will have to use Groose's Groosenator and launch yourself towards The Imprisoned's head.

That's all there is to it. Don't worry if The Imprisoned is about to go near the temple on round 3. You will be given some amount of time before it gets near it, so be sure to dash on over to Groose before... you know what happens next.
