Rupees are the currency of Hyrule and Lorule, essential for renting and eventually purchasing items from Ravio's Shop, as well as buying potions and other consumables. While you'll naturally collect Rupees throughout your adventure, there are several efficient ways to farm them if you find yourself short on cash. One of the best methods is to repeatedly play mini-games that offer good Rupee payouts, such as the Cucco Ranch mini-game or the Octoball Derby.
Another effective strategy is to explore areas with many pots, bushes, or enemies that drop Rupees. The Lorule equivalent of the Desert Palace often has many enemies that drop high-value Rupees. Additionally, keep an eye out for large Rupee deposits in hidden caves or behind bombable walls. Investing in the Big Bomb Bag and Big Quiver from the various shops will allow you to carry more bombs and arrows, which are crucial for both combat and puzzle-solving. purchase the Nice versions of items from the Street Merchant once you've bought them from Ravio, as these offer significant performance boosts.
