Soul torches are a type of light source in the game Minecraft. They emit a soft glow and can be used to illuminate dark areas, helping players navigate and prevent hostile mobs from spawning. Soul torches are crafted using sticks and soul soil or soul sand, giving them a unique blue flame appearance. These torches have a lower light level compared to regular torches, making them ideal for creating atmospheric lighting or for use in specific builds. Soul torches can also be placed on various surfaces, including blocks and walls, adding versatility to their use in the game.
