For some reason I keep on getting falling stars. It also happened in BotW and now again. Maybe because I don't really pay attention to them but at one gameplay I got at least 6 in a row. In BotW there was this trick you could use to make the falling stars appear every time but I don't know if it still works. You had to teleport to a shrine and make a fire and wait till evening. And then a falling star appeared.Okay, grinding for upgrading armor has got to be the most patience-inducing exercise in this game.
Even after buying out the butterflies you need, you can at least try catching them on your own.
But certain lizalfo parts drop at random and there might be enough in five moon cycles to upgrade all you need
but the captain constructs are definitely a sparse number!
Getting there though, just real slow…
Also, I’m cursing myself for every time I passed up on getting a fallen star.
