For gpz% (first 2 clips) and forgotten corners (second 2) saves several seconds if you have wings, cdash makes it easier (fireball skip version is kind of tight imo). camera is a bit weird but fixes itself after a couple seconds as you see. jumping straight up to the platform (3rd clip) is possible but it's easier to just dash left if you aren't confident and that still saves time
(dropping off the platform at start like i did isnt part of the strat, its just to fix my savestate so that the camera moves)
more lenient and more consistent ending setup for soul catcher early control. you have a lot of iframes, so wait until you see the baldur start to curl up and then move to the left side of it. warning that you CAN go too far left so dont just hold left and expect to get hit since you need the iframes for when the baldur comes back.
Here is all the boss battles in 112 and 107 where flukenest has been found to be either optimal or viable/ preferable over the non flukes alternative. I will first post the unambiguously optimal fights and then post the ones which may come to preference.
Nosk: Good RNG fight saves 10 seconds over non flukes combsob. Bad rng isn't super punishing as nosk has a lot of attacks where he can get multihit, you shouldn't be losing more than 5 seconds. If he goes into the ceiling instantly you can shriek as usual.
The charm loadout is: Shaman stone, spell twister and flukenest, needs overcharming.
Collector: There is a completely consistent quickkill which has been posted in strats before. Additionally, flukes will instakill collector out of the final phase. In total this is seven seconds of timesave over perfect shriek only fight.
Charm loadout is shaman stone, flukenest and dreamwielder. Charm switch optimally at tram bench or at oro bench for a safety heal.
Watcher Knights: Saves 5 seconds on average over optimal shriek fight. Each watcher dies in three fluke casts, so you can kill them before they even attack. To make up for the lack of twister i have come up with a couple of strats to gather soul (showcased in video). Its still optimal to throw the chandelier down, and the fight needs to be started with full soul.
