Doing this shade soul into cdash in the first room of frogs seems to get me much more consistent low times. You activate the frogs later in the room during your cdash so they have less time to move around and get in awkward positions. In the next room you can dream nail the fool eater to regain the soul used on the fireball.
Note that you want to hold cdash a bit longer than usual; since it stops charging during the freezeframes but the sound keeps playing it's very easy to release it early if you go with your usual cdash greed.
LK Dash Attack Storage If you stagger Lost Kin during its aerial dash attack animation, it skips the landing phase and still thinks it's supposed to dash. Even if it pulls an empty hop or down stab, air dash always overrides them. You can manipulate this to chain air dash triples multiple times with the right timing. (s/o to Magnetic Pizza for helping me figure this out lol)
In order for the dash attack to be stored, Lost Kin needs to be staggered during the "Dash Attack" animation (green circle). If it enters the "In Air" animation (red circle), it loses the storage. Getting the third fireball tick to hit lost kin before the animation ends is a bit tricky, so watch the video on the left and practice the timing. You want to shoot the fireball at about the same time as LK starts the dash - just be careful because if you shoot too early you'll single hit. Even when you're not in the stagger lock, be on the lookout for the air dash attack and see if you can stagger during the dash animation - the dash anticipate animation lasts a long time so make sure it's not staggered until the dash starts to get the storage.
The video on the right shows an alternate stagger rotation that could be viable for LP. The extra nail hit will get the stagger count up to 7 after the triple, and on 1.2.2.1 it will still get tripled fairly consistently. However, it can be awkward/rng to triple the air dash with the extra stagger hit, so I would recommend only trying that on later patches.
When the dash attack is stored, Lost Kin can do a grounded dash 28% of the time which is worse than an aerial dash because you can't keep the storage (at least not consistently) but you can still triple it if you fireball early enough.
Faster, more consistent start setup for TE Radiance. You still wanna start with full soul but only shoot 2 fireballs at the start, then dash in and buffer 6 nail hits like this: Pogo --> Side slash --> Wings side slash --> Side slash --> Pogo --> Pogo This puts you at a good height, refreshes your dash, and leaves you with full soul so you can react to any pattern she does and get double hits. Getting the nail hits in time and dodging certain attacks can be pretty tricky. If you feel like you were a bit slow, prioritize dodging the attack over getting 6 hits; the 5th hit is also a pogo so it's better to lose the hit of soul then get hit right at the beginning of the fight for double damage. If she starts with the triple laser, it's important to react to the laser placement so you don't dash directly into one, then just make sure to only fireball when you have an opening and save your wings to stall in the air if needed. If she starts with the sword burst/aoe, you basically wanna do the same thing but it's harder because the attack is faster. In general, it's better to stay in the middle verticaly when going for slashes so you have the option to both dash left and right, sometimes this also makes the sword burst miss completely. If she does a passive attack and you dash in the same direction she teleports, just dash the other way and spam shade souls, you still have time to get at least 2 double hits, but usually you can still get 3. Of course remember to delay subsequent fireballs ever so slightly so they're not i-framed.
Update: It's faster and safer to do a nailcancel at the beginning so you don't have to shoot the extra fireball at the end. You'll have to delay the second fireball less but it's consistent once you get a feel for it, and you don't have to worry about dodging the boomerang if you get the good RNG. If he doesn't backup, do the same damage rotation from before without the last fireball. Once again you only need 6 soul entering so you can still do firebell.
Shade soul double setup for the white palace kingsmould with a reliable backup for bad rng. Stop cdash around the rightmost poll, dash and buffer 3 nail hits, jump and delay a fireball. You want to stay in the second to left orange box (just to the left of the door) where it can either dash back or swing. If it dashes back, the shade soul should double consistency with good execution and two more single hits will kill. If it swings, get a nail hit and dash --> two nailcancels --> shade soul as shown in the video. This saves 2-3 seconds but you need 6 soul going in, so it's only worth it if you have dream wielder, in which case you would dream nail the devout in beast den and firebell as normal.
a variant of shade soul shaman stone 1 cycle for uumuu. first example is with extra, second is without. important points to watch out for are keeping uumuu at the right spot after the 3rd attack (slightly off the right end of the center platform), and delaying the first shade soul a little bit to make it double more consistently. an extra sets up perfectly for the original 1 cycle setup that you see most often. can be mirrored across the center if you feel more confident with the extra setup moving right than moving left.
an easier setup for wcs than scruffy's and w/o having to learn any timings stop holding jump once you're above the lantern, then when you're far enough right to pogo the soul container tap left and pogo neutral, buffer the jump and dash when you're around the height of the crest in the door(its better higher than lower), if you're too close to the door you can do a wiggle after the jump once you hit the ground jump(don't buffer or you'll jump in the wrong direction) and immediately neutral, this should put you close enough to talk to the shaman, if you're not you're dashing in the door too low
i haven't timed it but this is probably slower than scruffy's bc they dash only once
idk turning seems to make the save icon appear faster after early control, finding more details on if its shade soul exclusive later [it is] and this only works on 1221
Small optimization to do the movement for shade soul. Allows you to send the elevator back down without having to wait for it to reach the top (where it delays a little before being able to be sent down again). Two setups - 3 hits is safer, you can't really send the elevator back down too fast. 2 hits is tighter, if you send the elevator down too fast you'll def lose time Safe (3 hits) :
