[Udon]

how to open that chest in bikinel? and in besaid someone gave me sensor. what's that for? i think its for opening another code in besaid cave.

this things are not included to get 100% right? i'm looking for faqs that talk more about these stuffs like hidden treasures or something

you need to look around besaid for code numbers, then you enter it and get a new garment grid from a secret place

They don't count toward 100% completion. I've done them both before but I forgot how. I will try to get back to this soon.
