MONEY THING:
ok here is how the money one works. you go into the divine beast cave and go to b1. then you just fight the monsters and see what they drop.for example dashers usally drop pricklies and they sell for 200 ea.!!!!!!other fish bait is kinda rare but you do get some though.this is related to the wep one!
ITEM THING:
okay here is the item one what you do is do not finish gafffiers buggy!
but finish hags house! whan you finish her house she wil use her closet to store items for you 60 to be exact!this is where the mayor comes in! he gives you these items.bread,tasty water,repair powder, and escape powder. and he will give you those items when you are out of them!NOTE:HE WILL ONLY GIVE YOU THE ITEMS THAT YOU DONT HAVE THAT HE HAS TO OFFER YOU!!!!!!!FOR EXAPMLE:SAY U HAVE EVERY THING HE HAS TO OFFER YOU EXCEPT TASTY WATER! HE WILL ONLY GIVE YOU THE TASTY WATER!!!!!!!!!
so what you do to get the items u finish hags house then keep on storing the items that you get from the mayor and just repeat the process u just keep on getting!
WEPON UPGARDE THING:
ok here is how this one works! go to the divine beast cave b1!then you just equip the wep.you want upgraded alot just clear out the whole dungeon then go out then go back in keep on reapeting the process until you want to quit!this is related to the item one you can do this and the item one at the same time!
