Lynel Guts are an item from The Legend of Zelda: Breath of the Wild. They are a rare monster part dropped by Lynels when defeated. Link can cook with them and critters to make elixirs. If cooked by itself or with other food ingredients, it will result in Dubious Food. It is required by Great Fairies to upgrade the Soldier's Helm, Armor, Greaves set, and the Barbarian Helm, Armor and Leg Wraps set.
