Vine Skip
From Horizon Speedrun Wiki
General
The Vine Skip is a skip that takes place during the Eclipse Base split in Horizon Zero Dawn that was found by everydayaussie on the 23rd of March, 2020. It saves around 8 seconds by using a vine on a wall in the Eclipse Base to avoid needing to take a zipline.
How to Perform
In order to perform the Vine Skip, you will want to enter the first area of the eclipse base (with longlegs and watchers). Make your way to the passage you would usually enter through, and find the vine somewhere a bit to the right. Jump up the vine and into the passage.
