Health & Magic:
Increase your maximum health by collecting Heart Pieces and Heart Containers from bosses. Your magic meter is obtained early in the game and can be upgraded to a double meter by visiting the Great Fairy Fountain on Death Mountain Crater as Adult Link.
Wallets & Deku Stick/Nut Capacity:
Upgrade your wallet size by collecting Gold Skulltula Tokens. Increase your Deku Stick and Deku Nut carrying capacity by completing specific side quests (e.g., Lost Woods minigame for Deku Sticks, Deku Tree for Deku Nuts).
Quivers & Bomb Bags:
Expand your quiver size by winning archery games in Kakariko Village and Gerudo Fortress. Upgrade your Bomb Bag by completing the Dodongo's Cavern and a specific Goron side quest.
While Ocarina of Time uses Great Fairies for magic upgrades, The Legend of Zelda: Phantom Hourglass evolves this progression by tying Link’s abilities to collecting Spirit Gems.
