I think that since there isn’t any glitches used in the run, the mods would probably put it into Glitchless Great Sky Island Any% instead.

If you want to learn more, I suggest you join the Tears of the Kingdom Speedrunning discord server and ask questions (If you haven’t joined it) And if you’re already part of it, still, just start asking questions so you can learn the route

1.2.0 AD is gonna need some major routing because the WR uses outdated strats and it was a long time ago. 1.2.1 AD uses a glitch known as “Invizuggle overload” to setup drop smuggle and do what’s known as a “cart slide” to travel long distances. 1.2.0 AD needs this along with the slight advantages such as quick smuggle for the GSI, heading to Lookout Landing, and heading to Hoz (I think).
