Mirror shield early:

I'm not great at hovering but even with my poor hover, I'm still close enough to the door when I get enough height to be able to leaf there
You have to start away from the wall like that because wall hovers don't gain height with chest storage
I've actually gotten this a few times now, it's easier than I first thought, this should be used for sure in a segmented run if one ever happens, maybe too risky for RTA though sadly
because I leaf right to the miniboss, I think a savewarp may be required to get out, since you haven't killed the poes/moblins to lower the stairs outside.
if somebody finds a way to get into the poe/moblin room from that side though, we could use storage off the joy pendant chest for the rest of the dungeon
to get up to that room in the first place, you'll need to hover up there I think (unless maybe you can run up the giant sun head somehow to get there)
