On the wiki it says that sealed chests, specifically Nimbus ones have the best possibility to give lost technique scrolls and just pop a luck potion , but I’ve seen differing answers on the internet, so I want to know the definitive best answer.
Marketplace.
If you’ve got money then the marketplace, if not then you could do diving spots, not only are they capable of giving scrolls but they can give other loot like acrimonies and sunkens
Absolutely not
Even for a rich player the prices for spells that are even considered remotely good is abhorrent
Yup, the prices are just too much when I already need to save money
