I dont know if anyone has posted it before, here but people on youtube always recommend to ice walk to that island, but i got there with gliding. Heres how

I use 2 wind char for -15% stamina consumption Amber for -20% glide consumption And last before gliding i use barbara skills for -12% stamina consumption and glide straight to the island

For the notes i have 176 max stamina And my stamina depletes right after i got to the island. It saves times like there 1-2 minute gliding away from the edge of starsnatch cliff Have tried this 3 time, one when i go myself and 2 when helping friend

Hope it helps!

Edit : its possible to do it without barbara initial skill but u will fall in the edge of island near the stairs on the beach

If ur stamina lower than mine i suggest trying this if ur stamina is 160 with barbara

Or u could use stamina foods too if ur stamina lower than 160
