Mirror Shield in Mirror Room Equips

the "issue" refers to not being able to do light, zora, bomb -> light, goron, bomb in mirror shield route (I made a mistake when counting equips last time)

No Mega before realizing issue/old route:
light, zora, bomb
light, goron, bomb
light, deku, oca
hook, bomb, chu    (damage isg)
hook, bomb, gfm

item: 1 + 2 + 3 + 1 = 7

No Mega after realizing issue:
light, zora, bomb
light, zora, goron
light, bomb, deku
oca, bomb, hook    (damage isg)
gfm, chu, hook
gfm, bomb, hook

item: 1 + 2 + 2 + 2 + 1 = 8

If not doing mega, the issue causes 1 extra pause + item equip (or 1 extra mask transition); either way mirror isn't worth it in this case

mega before realizing issue/old route:
light, zora, bomb
light, goron, bomb
oca, chu, hook      (chest isg)
bomb, gfm, hook

item: 1 + 3 + 2 = 6

mega after realizing issue:
light, zora, bomb
light, zora, goron
light, bomb, oca      (damage isg)
hook, bomb, chu
hook, bomb, gfm

item = 1 + 2 + 2 + 1 = 6

If doing mega, the issue causes 1 extra pause, but allows for damage isg, so that roughly cancels (see https://www.youtube.com/watch?v=PTkHvvaY6mA).
