Blue fire fly visual effect is a vfx item in Valheim. Its in-game item ID is FireFlies, which you can drop into the console with spawn FireFlies to give yourself one — append a number like spawn FireFlies 50 to spawn a stack. Blue fireflies are a small visual particle effect found in the Mistlands at night. They are purely atmospheric and not interactable. The spawn command requires cheats — enable them with devcommands after opening the console.
