You're right. I think Flymode is enabled only when you have the lantern. Before and after that its turned off.

Not really. This trigger is like a one or two shot thing, if you miss it just keep going really or reset .

Here's my attempt at Cave of Harmony Flymode Trigger:

And yeah https://splits.io/2anc , I lost a lot of time while entering the Archives, my monastery was a slow strat, no OOB. About the strats its mostly movement practice/optimization and wall jumping, maybe you lose it to loading times we would need to time the difference.

With all of the time saves feom the out of bounds. You can actually almost go under 30min. My Pb is 37 but the leaderboards as not been updated yet.

I don't know if it saves time but i found a way to trigger it in Cave of Harmony too. I'll post a video once i find a consistent setup.

I'm so glad that there is a way to make the run more interesting and more challenging! Thank you person from the internet.
