Beginning Fleur Skip
From Horizon Speedrun Wiki
The Beginning Fleur Skip was found on the 24th of October 2020 by Fleur_Bleue101. It involves jumping onto the side of a wall, followed by jumping onto a torch, and then optionally jumping between 2 walls to skip the last climbing handhold as well. This skips the first and possibly the second handhold depending on the version used. This skip saves around a second, though it is uncertain whether the version skipping only 1 handhold even saves any time.
Video of the 1 handhold version:
