What if there was a speedrun completing the Champions Ballad as fast as possible. This would include the One-Hit-Obliterator section, all Champion Songs, and the Divine Trial. The time starts when you gain control of Link when you have the One-Hit-Obliterator. The timer ends when you hang the picture that Kass gave you in your house. You must ride the Master Cycle Zero to your house in Hateno Village. Any glitches you find would be allowed. I'm not sure if it would be a Level Run or a Full-Game Run.

So basically DLC%? It would be classified as a full game run because you need to complete all Divine beasts to beat it.

Well he said once you interact with the one hit obliterator, so

Time starts when you are in the Shrine of Resurection with the Obliterator equiped. (Which is automatic)

What sounds fun about this idea is how safety saving is out of question.. unless you're ready to set up a new file every time after you're done/reset lol

Right. I would have different videos because I don't have the stamina to do it all in one run.
