not sure if you still play or not but I use this route and one thing im having trouble with is the leyline is spawning over by the Amber domain and not by the statue just before you end the run any suggestions? If you still play
I missed the notification of your comment sorry. It's quite normal if you have trouble to have the ley line spawn in the correct location because it's random as far as I know. Ley lines can either spawn where it is in the video or in the Thousand Winds Temple area like you experienced. It makes running this category really random unfortunately.
Outside of AR10 and Prologue% I've also completed a Chapter1% run in 10h30mins. It's not available on yt for obvious reasons but you can find it in my vods on my twitch channel. Since then I've been on an indefinite break from Genshin. I do plan to come back when new early game content gets released (something that could change Prologue%).
