Zelda games have always had plenty of items to collect, but never before have there been so many new materials to discover across the vast land of Hyrule. In Breath of the Wild, players will need to forage and stockpile materials in order to survive. Some of these materials are consumable and will refill a small amount of hearts. Many of these items can be cooked together over a flame to create more elaborate food dishes that will yield more energy and even special attributes.
Unlike prior games, Rupees aren't found simply by cutting grass and throwing pots. Although a couple of media outlets did come across a Rupee in the wild, for the most part the E3 demo didn't have any of the Hylian currency. Some of the materials you collect will be able to be sold for Rupees, such as minerals like Sapphires and Rubies. Of course, with an elaborate crafting system in place, it might be better to hold onto these valuable minerals to augment your favorite items.
Remember, we've only seen about 2% of the game, so the materials listed below are only a small sample of what the full game will contain. Despite pouring over hours and hours of footage, it's very possible we missed some. If you notice any missing, please let us know what's missing and where the footage is so we can grab a screenshot.
