max% child items still needed
-fire arrows (rta viable method)
-double defense (wrong warp exists but requires fw ww from jabu, and jabu ww is already used for ww to dc, which then leads to fw ww to nocturne)
-quiver upgrade (40/50)
-song of storms (would also give 2 more heart pieces (frogs) and 1 more gs (hyrule castle sos grotto))
-prelude, minuet, bolero, serenade
-light medallion, spirit medallion
-biggorons sword (can rba broken giants knife)
-adult trade item higher than odd potion (poachers saw would give access to prelude and serenade, then we could also trade it for broken sword and rba spirit medallion)
-twinrova heart container
-beating ganon would be nice if it didnt require skipping an item (would need a 3rd wrong warp to ganons castle OR wrong warp to lake hylia lab without using ganons castle collapse timer OR beating ganondorf as child)
pretty sure the rest of the heart pieces/gold skulltulas left (aside from the ones mentioned above) are all ones that only exist as adult
