Me: 150 hours wandering around and just starting the main quests "I need 15 of these... what you already have it! I need you to go there... oh! you've already been there!"...

That's the one I was gutted by. 100 hours in, eating zonai balls and strapping batteries to every build I discovered you can just extend your recharging battery.

The what now? °° I mean, I know there is one in the starter sky island, but I haven't found one on the surface yet.... dang it, I need to pay more attention, lol.
