PSA there are still missable items during story of 3.0

So with a notice saying how the item "Nikador Battles the Rosy Celestial Maiden" will be made available in the coming version, I wanted to remind collectors of the game that there are still missable items that Mihoyo has not explicitly said will be made available after they are missed.

The missable 3 items in question.

These 3 items appear in the main story just after unlocking the final map of 3.0, '"Bloodbathed Battlefront" Castrum Lremnos.'

Map location of the NPC that sells these items.

The NPC that appears in the quest that sells these items. You only get one shot before he disappears.

I also want to remind everybody that if you did miss them and still want them, maybe try sending tickets to try get get Mihoyo to make these available just like they did with the Rosy Celestial Maidens item or the Saurian Biscuits from Genshin.

I will say however that if these items do not come back, collectors in Hoyoverse games may need a strategy guide on these missables before ever even beginning any quests. Kind of sets a bad precedent IMO. GL&HF with the rest of 3.0 folks!
