Deep Firefly is a critter in The Legend of Zelda: Tears of the Kingdom. The game describes it this way: “A multi-winged insect that lives in the Depths. It excretes luminescent elements that can be cooked into an elixir, which will add a faint glow to anyone who consumes it.” This page shows where it is placed, explains what it does in a dish, and adds up what the armor upgrades need.
