First lure the vicious caranid, after that you need to pogo its attack twice and then either damage tank (getting extra airstall with dash) or pogo several times. It's actually pretty easy to do once you get used to it. I did it with 3 extra needle hits and 1 extra hp to spare. Make sure you have full silk. (Technically, 5 is fine, since there is 4 more silk in the next room)
Then the tas part - you need to do a double thornjump. I assume it's easier to do at 60 fps, but there is nothing more to say here, just maneuver around the thorns.
And finish it all with a bind stepjump into upslash.
It should be faster than current strategy (getting float), even with my poor execution (since I am lazy) it's sub 2 minutes.
The tas part can be replaced with a cocoon skip, but it makes the strat slower. I guess you can also do a bdr into silkeater but this is rando-only.
I haven't seen anyone other than sclicheD do this airstream skip. It replaces the tall airstream and slow float left with a sprintjump and shorter airstream. Probably saves 2-3s.
Decently fast shard arena. Make sure to have enough silk for 2 spears for the last wave, if youre short you can get a hit off before the first of the two spears.
Figured out a consistent setup for a heal skip in deep docks. You can get the silk either in the room or before. Guide with examples here: https://youtu.be/J9oTLOPXuYA
