Spirit Temple
Part 1, Young Link:
Go up the stairs and turn left. Talk to the person there. When asked what you want, say Nothing, Really, and when asked if you like Gannondorf say no, and then you'll be asked to go get a treasure. Crawl through the hole, kill the bats and statue guy, and then light a Deku stick with one of the torches. Go through the right hand door and light the torches in there. Then go back and go through the other door. You'll have to fight a Stalfos here (boy they're much tougher and scarier when young Link aren't they?) and also a flaming green skull (stun it with your boomerang and then hit it with your slingshot). Now throw your boomerang to the left of the shock switch across the pit from you. If you aim right it will swing around behind the fence and hit it. Then the fence will fall down forming a bridge. Cross the bridge, watch out for the flying pots, and go through the next door (the chest is 5 rupees or a Deku Shield if you lost yours).
In this room walk along the bridge until you're just before the spike thing and then use Din's Fire to fry the guy. Just so you know, these guys copy all your movements, except in reverse. Technically you can lure it into a pillar of fire that appears when you hit the shock switch nearby, but it's easier to just fry them. There's nothing on the other side of the bridge, so just go through the next door. Open the treasure chest here for a key and collect all the silver rupees to make a bridge. Now go back into the first room again and this time climb through the small hole (not the one you came in through, the one between the two torches). Go through the locked door. Kill the skulltulas and climb up the wall.
Now you're on floor 2. Go in the room a ways and you'll have to fight two of those lizard guard guys. Use your boomerang to hit the shock switch above you and open the chests that appear. One has Bombchu's in it, the other a Deku Shield or 5 rupees. Aim a Bombchu so it climbs up the wall and hits the boulder up there. This will open the doorway. Go through and look to your left. Push the stone statue you see straight off the ledge onto a switch. Climb the steps in front of you to get to a torch and a door. Light a Deku stick with the torch, drop down, and light the two torches in front of the big statue to get the Map. Go back to the small statue, climb the wall, and go up the steps again, this time going through the door. Go around to the next door, and you're now in another silver rupee-collecting room. You'll have to kill the laser eye guys with bombs or bombchu's to get up to most of them. After getting them all a torch will light. Use it to light the other torches to get a chest with a key. Now move those blocks in the middle of the room around until the one with the sun symbol on it is in the sunlight coming in from the window. Go through the door that opened, up the stairs, and into the next room. Go up to that big metal thing sitting in the throne and hit it with your sword. Now you'll be up against an Iron Knuckle.
This guy isn't all that tough. If you get hit though, you're in for some serious pain. Just Z-target and go to right outside his attack range. Then Jump attack (push A) and you'll get off a good hit and the swing he takes at you will miss. Back off and then do it again. If he hits a pillar it will give up 3 hearts. You can also try getting in behind him when he misses a swing if you're good. After a bunch of hits he'll be dead. Go through the door that opens and up a ramp and you'll end up...outside. Open the chest there to get the Silver Gauntlets. Watch the story sequence then play the Prelude of Light to go to the Temple of Time. Get the Mater Sword to become adult Link. If you want you can go back to get the Ice Arrows from the Gerudo Training Grounds using your Silver Gauntlets, or continue on to the rest of the Spirit Temple.
Part 2, Adult Link:
Play the Requiem of Spirit to warp to the entrance of the Spirit Temple and go on in. Go up the stairs and to the right is a big gray block. Push it until it falls down and go into the next room. Kill the eye laser thing and shoot the shock switch in the ceiling with an arrow. Go through the door on the left. Kill the wolves and play Zelda's Lullaby on the Triforce symbol to make a chest appear. Hookshot to the chest to get a Compass. Go back and now go through the door on the right. Collect all the silver rupees in this next room. Use you Hover Boots to get the one floating in the air. Go through the door that opens. Watch out for the Shield-eater and get a small key from the box. Go back to the room with the shock switch on the ceiling and go through the locked door.
Watch out for flying pots and a Shield-eater that falls from the ceiling in this hallway. Climb the wall and use your Lens to see an invisible hand monster. Kill it, then use one of the wood poles sticking out of the statue to push it around to the third sun symbol from the left, opening the doorway. Go through it and you're back in that giant statue room. This time the small statue next to you is alive so watch it. Climb up the stairs and jump onto the statue's hand with the Triforce symbol on it. Play Zelda's Lullaby to make a chest appear in the statue's other hand. If you've got good aim you can hookshot to it, or just drop down and climb the other stairs to jump over to it. Inside is a key. Climb up the stairs where you came in (there's a hookshot target on the ceiling above the door you came in that you can use to get up there) and go through the locked door.
Kill the eye laser thing with a bombchu, then go through the next door and kill that eye laser thing with a bombchu (it will go down the wall, across the floor, and up the other wall to get it). Kill the weird floating guys with fire arrows or try luring them into the fire that appears when you step on the switch. Go through the door that opens. Ignore the statues and go stand next to the closed door to your right. Equip normal arrows and fire one at the statue furthest from you. As it moves toward you it will step on the blue switch which opens the door, so quickly go through it. Go up the stairs (there's invisible chests in here with hearts in them) and through the door. You'll have to fight another Iron Knuckle. This time is a little different since you're now older Link. If you use the Big Goron's Sword you can stab by pushing forward+A and then quickly retreat to get in hits before he hits you. Using this sword will kill him in a lot less hits then it took young Link to kill him with. If you don't have the Big Goron's Sword wait until after he's done swinging his axe and then hit him. Once he's dead go through the door to end up outside, and this time the chest holds the Mirror Shield.
Go back inside and down the stairs to the room with the four statues. Stand in the sunlight and use your Mirror Shield to reflect the light on to the sun symbol on the wall. Go through the door that opened and get the key from the chest. Go back out of this room and then take the door to your right back to the room where those weird floating guys were. Go through the locked door here. Kill the two eye laser things with Z-targeting and a couple of Bombchu's (BTW your new Mirror Shield can now block their lasers!). Shoot down the skulltula halfway up the wall. Now aim your hookshot at the climbable section of wall at the very top and fire it. You'll be pulled up to the top climbable section rather than having to navigate this moving wall. At the top you have two more eye laser things to kill then go through the door. Play Zelda's Lullaby on the Triforce symbol to open the door in front of you, then go through it. All the doors in this room are fake. Blow up the one just to the left of the chest to reveal a gold eye. Shoot it and another block of ice will appear above you. There's a hookshot target on the ceiling above it to use that to get up onto the new ice block, then jump over and step on the switch. Drop down and get the Boss Key, then exit the room.
Turn right and go through the door. Watch out for flying pots, and hit the switch behind the grating with a spin slash. Go through the door that opens and kill all the baddies in this room. You can use the Mirror Shield to reflect the light onto a sun symbol above the archway between the two sections of this room to get some bombs. Blow open the wall to the statue's right then push it around so the light shines down the new passageway. Go down there and push the second statue so the light shines back into the previous room through the grating. Now go back into that room, drop down to the floor and stand in the light. Reflect it onto the sun symbol on the wall with your Mirror Shield and you will be taken down to the big statue room again. Stand on the side of the platform furthest from the statue (but make sure you're still standing in the light), hold your Z trigger for a second to get the camera focused on the statue's face, then let go and use your Mirror Shield to reflect the light on to the statue's face. The face will crumble off and a grate will be behind it. Hookshot to the grate and go through the Boss door behind it. Watch the short story sequence and you'll have to fight a third Iron Knuckle. This one is bigger though. First Z-target him and get fairly close. Then wait for him to start to swing his axe. Immediately push Back+A to do a backflip, then push A again as soon as you land to do a Jump Slash and nail him when his defense is down. Then just wait for him to come close and start another swing and do it again. Once he's gone, watch another story sequence then go through the door behind the throne. Go down the hall, through the door, and climb up onto the big square platform. Step in the middle of the platform to initiate the battle with...
Spirit Temple Boss: Twinrova
First, jump onto one of the 4 side platforms and face toward the big platform in the middle. Keep facing toward the general direction of the witches. Do NOT Z- target. When one of them looks like she's about to fire, face her and hold down your shield button. Her beam will reflect off of the shield. Try to direct it at the other witch by moving the shield. If they fly over and start hovering above your platform, jump to the middle platform and reflect the attack, then jump back onto your platform. After you've gotten them to hit each other enough times, they'll combine into a more powerful (but much less ugly) Twinrova. Jump back to the main platform. Z-target her and hold down your shield button. Your shield will absorb her attacks! After three of the same type (fire or ice) it will fire back at her. She'll fall down to a platform. Let off your Z targeting, get over to her platform (Hover Boots may be useful here) and let her have it with the sword. Then get back to the main platform and repeat the process. NOTE: If she fires an attack of the opposite kind of what your shield is absorbing (an ice attack when you previously absorbed a fire attack) just dodge, don't try to absorb it, otherwise you'll get hurt enough to lose 10 hearts!! Watch the somewhat funny death scene, grab the heart container, and step into the blue light.
