Action swap is useful in this room to melt the ice covering the door leading to the central room.
From here, there is no way to push the block and keep action swap, so clipping through the block is required to use action swap on the ice.
Backwalking with certain angles will cause the icicles to push Link into the block. One such angle is parallel with the block's face.
This video shows another way to clip.
Position Link on the ice before the bridge. Begin a roll from a standstill in order to have time to get spikes, and aim the roll directly along the bridge. Begin holding left notch midair to roll directly to the door on the other side.
Three simple ways to cross this room are:
The second and third options can be seen in the video below.
This is another method of reaching the 2nd floor of the dungeon without fire arrows. From the position shown in the video, a 1st or 2nd frame weirdshot will put the chest in range.
For documentation purposes, as it is not immediately obvious that one can skip the invisible platforms in the map chest room to get to the fairy with a well placed hookshot.
It is slightly faster to Goron roll down from the chest than to jump down as human before transforming.
A roll with a good angle and timing can hit the switch under the ice to spawn the fairy chest without melting the ice. This is somewhat precise.
Long jump to the crate, then recoil flip into the ice to hit the switch.
Long jump to the crate and then jump to the next platform, then jump onto the ice to press the switch.
Climb the ledge roughly where shown. Turn left, begin targeting, and pull a bomb. Hold forward and throw the bomb towards the snowball. While still targeting, hold forward and slightly left to jump to the upper platform and grab the ledge.
Align parallel to the door and shield drop a chu after 2 flashes.
A jump as Zora or a long jump as human can cross the gap.
It is slightly faster to kill the first freezard with the sword, as it allows Link to get closer to the chest before the cutscene begins. When moving after fire arrow shots, tap shield to be able to roll sooner.
It's possible to hookshot from the second floor of the dungeon to the third without calling the scarecrow to use in between. The position and aim required are somewhat precise, so using a setup can be helpful
Go to the small white seam in the texture (shot with hookshot in video) and target the wall. Hold backflip, then aim just above the upper ledge.
Long jumps can be used to get from bridge to bridge without Goron Mask.
This setup works for any of the four bridges on this level and can be mirrored to go right instead of left.
Releasing target midair in step 6 will cause Link and the camera to flip, which is not necessarily a bad thing as long as you know to expect it.
Walk to the first black line on the bridge and transform human. Equip Fire Arrow. Target, hold left, and press A during unpause lag to tap sidehop, then pull bow midair to stop horizontal momentum.
This takes 5 hovers, but as a rule of thumb, if you hear the snowball explode, you're close enough to backflip to the platform.
The setup written out below looks for specific frames for a consistent jump, but these components are not frame perfect, and the trick can reasonably be done unbuffered. See the remote hookshot page for more details on the underlying mechanics of this trick.
To get the fairy in the room with the freezards blocked by ice blocks, one can either do a wastefully long hover from the basement, or opt for a more clever method that doesn't require ISG. On the walkway outside the top locked door in the main room, doing a recoil directly underneath with the right timing will put you on the ceiling of the fire arrow room, but out of bounds (The most tried and true method is recoiling after a small jump off the platform). From here, a jump to the left is enough to make it to the room with the switch you normally have to goron pound. Enter the door here to get in the room.
There are multiple ways to get to this fairy without taking the slow flower ride from the top of the room.
As Goron, open the door, target, and shield turn down-right. Backwalk off the platform and begin holding right as soon as Link begins to fall.
Hookshot to the top floor standing a bit to the right of the left corner. This aligns perfectly for 2 right sidehops, putting you directly in the alcove. To get back up, go to the left edge and hookshot the torch you sidehopped from.
To help time the bomb throw, while running forward, pull the bomb when Link crosses the first black line, then throw the bomb from the right corner at the third black line.
These backups get Link into the tunnel from above.
The faster method is to do a quick goron roll. However, this can be hard to control. A slower but easier method is to curl and hold up-right from the initial position after climbing the stairs. Both methods are shown in the video below.
With a superslide or recoil flip into an acute angle, it is possible to land directly into the unloaded second wizrobe room. From there, open the door that leads to the boss key. Alternatively, it is possible to get directly into this room by taking the flower just outside of the boss door through the wall above the key. Once in this room, it is impossible to get out without deathwarping, song of soaring, or going back and fighting the wizrobe. Due to this, in instances where one must get the boss key it usually better to just fight the wizrobe normally.
This is also possible without a megaflip using more explosives. Note that stepping on the ramp at the end of the ice platform will get rid of ISG.
Target the facet of the icicle shown, then simply backwalk into the load zone.
The jumpslash is not always needed, but it is safer to do it, as not making it to the load zone means falling down one or more floors of the dungeon.
