After triggering the kargarok cutscene, wait for the bulblin to stop firing arrows. Transform human and wait near the water. Once the kargarok is becoming visible over the hill, swim into the water and put on the iron boots to sink to the ground. When the kargarok tries to follow Link into the water, it will kill the bulblin while failing to grab Link, and the fight will end. This is about 6 seconds faster than a normal fight.
After killing the bulblin this way, Link will start the kargarok flight as human instead of wolf. It is recommended to transform into wolf as soon as possible during the flight because human Link spawns on an out of bounds ledge, which causes the camera to go crazy as the kargarok flies. Also, touching the control stick before transforming will cause Link to fall off of the ledge, and it is then impossible to transform while Link is falling.
WARNING: If the kargarok grabs human Link deep enough in the water to kill the bulblin rider, the game will crash. It is not possible to recover from being grabbed, but it is possible to input the soft reset combo (start + X + B) as soon as Link is grabbed and soft reset before the game crashes.
Once the bulblin stops firing arrows, get on the slope and wait for the kargarok to get close to the ground. Jump on and attack. After getting off, backflip once, then jump attack back onto the Kargarok. Kill the bulblin with a Midna charge once possible.
Clipping out of bounds makes the kargarok flight faster by making the path to the load zone straighter. This saves around 6s.
Here are some visual cues to help with the easier clip. Flying to the right will help give the same angle as in the pictures.
It is also possible to clip out of bounds earlier in the tunnel. For getting to UZR, this is slower than the later clip and more difficult if transforming from human to wolf during the flight, but it is useful for Iza 1 Skip.
Flying to the loading zone OoB is slightly faster than clipping back in bounds.
Once at Death Mountain ready to warp the meteor to Zora's Domain, dash behind the chained rock and transform into human before the meteor falling cutscene. Then, warp the meteor to Zora's Domain as human. There is a 1-frame window where a sidehop to the right will skip the Midna text. After the sidehop, hold down-right and put on the boots to go under the arch; otherwise, hold down and roll to get to the arch, then use the boots. Exiting under the arch skips the trigger for Rutela cutscene.
During the twilight, after collecting the tear in Zora's Domain, the trigger is still present and will need to be skipped again to save time. This time, though, the next destination is the upper right hand ledge. To avoid being swept all the way down the waterfall, either perform Waterfall Sidehop (below, faster) or hold L and right to line up as far right as possible without getting stuck on the archway, then put on the boots after passing the archway. Walk out to the side pool before taking off the boots to get out.
After doing Rutela Skip during Lanayru Twilight, it is faster (but harder) to sidehop to the right at the edge of the waterfall instead of going all the way around and dropping down from above. This sidehop is possible on 6 frames: Sidehopping on the later 3 (frames 4-6) will put Link on the higher (ideal) ledge, while the first 3 (frames 1-3) will put Link on a lower ledge from which he can clawshot to the vines on the higher ledge. Failing to sidehop within this 6-frame window will result in Link following all the way down the waterfall, at which point savewarping will place him up near the load zone to inner Zora's Domain and is the fastest backup.
1. Open up the item menu as soon as the A button appears on bottom of the screen. If the route calls for an equip here, do so. (It is also possible to do the trick unbuffered.)
2. Hold L + Right and close the item menu.
3. Swim until Link arrives at the edge of the waterfall after 4 swimming strokes.
4. Soon after Link hits the ground underwater, sidehop right. A good visual cue for this is Link's right arm extending out for the 4th time.
5. Transform wolf and Midna jump up to the bug.
It is 0.86s faster to hug the left wall at the start and skip killing the first bug as it will catch up later as shown in the video below.
It is also faster to fly above the rocks and hug the wall rather than underneath as the path is shorter. This was discovered by gymnast86 while creating the Any% TAS. Finally, it is also possible to bonk off the inner wall with the same dash used to kill the final bug. This is risky, as the amount of time it takes for Link to finish collecting the tear is variable, and it is possible for Link to fall into the water before fully collecting the tear, necessitating redoing the entire kargarok flight.
For cycle 1/3, wait for the bug to finish attacking, then jump attack and bite it as intended.
As soon as possible move Link to the opposite short edge of the plank as shown in the video and enter first person. This will manipulate the bug to approach Link head-on.
When the bug comes charging, backflip twice, hesitate to wait out the bug's attack, then jump attack. If done correctly, this will hit the bug as soon as its attack ends, causing it to hang in place momentarily.
While the bug is hanging in place, jump attack it once more to latch on and bite it for cycle 2/3. It is common for the bug to be partially clipped into the plank while hanging in place, and if Link tries to latch onto it while it's clipped, then he will bounce off. If needed, delay this jump attack until the bug is no longer clipped into the plank, but don't delay so long that the bug gets away.
For cycle 3/3, repeat steps 2-4.
Once the bug is upside down in the water, Midna charge from right next to one of its upper legs so that the attack will propel Link into the water after hitting one leg. This will finish the fight more quickly than if Link successfully attacks all 6 legs.
Saves 0.4s but is much riskier. Can be used in Twilight or for getting to the poe in 100%.
An old 100% route (Fixed EMS) entered Lanayru Twilight from the normal entrance and then used the shortcuts to get down, skipping various things including the kargarok flight. This was done by deathwarping in Iza's lodge coming from Zora's Domain. This required an LJA using the howling stone promontory to get over to the door. This LJA's target is not precise.
There are several instances in Lanayru Twilight of single frames between cutscenes and/or text boxes where inputs can save or lose time:
