Name every (button slot equippable) item in every zelda game
clarifications:
trading quest items will not be included.
upgraded items are listed seperately.
zelda 2 will be the dungeon items.
ocarina of time will not include anything on the equipment menu in both versions (as long as it's in the item menu in either version, it will be included).
majora's mask (and ocarina of time) will not include masks.
Wind Waker will not include anything contained in the spoils bag or delivery bag.
skyward sword will only be B button equippable items.
breath of the wild will be rune abilities.
tears of the kingdom will be all L mappable abilities.
Echoes of Wisdom will not be included, as the only thing to include would be echoes, and that would be half of the list on its own.
bottle contents will not be included as separate items.
swords that are equipped onto mappable slots will count
You didn't list the criteria of included items in BOTW and ToK so it wasn't clear what was expected, and certainly what was is not what I would have included since those aren't even technically items.
The criteria are in fact listed above, it says all runes for breath of the wild and all L mappable abilities for totk. I do need to do some combinations down there though...
