It really depends on the type of item that you are looking for, as certain items will only be found by visiting certain areas and partaking in certain activities. However, outside of engaging with every aspect of this game, here are some tips for finding rare items that you would maybe not have access to without doing very specific things: • When fishing, always try to catch the treasure as well as the fish. This can often lead to obtaining rare items. • Be sure to mine regularly; a lot of the best loot is hidden in the Pelican Town Mines, Skull Cavern, and out on Ginger Island. • Look out for worms on the ground and always hoe that tile; it can often be a rare artifact. • Visit the Travelling Merchant every time they visit. They often carry items that are rather hard to procure.
