I'm interested in learning the current any% wr strats but I can't find much info. The healer glitch is straightforward. But I don't understand alot of the routing after getting the glitch. Does anyone know of a tutorial or guide explaining any% in depth? Thanks in advance!

Unfortunately, there's no single any% tutorial about the current route. An any% run is conglomeration of almost known z2 glitches and previous any% routes:

1. Basically, the healer glitch does some variation of the "scroll lock" glitch, where if you want to exit right in a side-scroll room, you have to scroll the room a little bit then exit left or just keep walking right. If you want to exit left, just exit left. In a palace, while scroll-locked, in a room with an elevator, to exit down, scroll the room right, then exit left. Or you can just go down the elevator.

2. There's also the 'link feet' screen wrap used in the overworld, reminiscent of the zelda 1 screen wrap so one can exit a room faster.

3. Finally, there's the HUD screen fairy warp to skip Thunderbird to get to Dark Link in the Great Palace. Fairy warp has been known since game came out but it's used here to skip Thunderbird.

In short, all those things are what makes the routing for any% possible.

Here's a really old any% tutorial using one of the very first routes

Here's a commentated run, precursor to the current route,

Awesome, thanks for the help! This will give me something to start with :)
