Soul Campfire
Item Details

A soul campfire is a dimmer variant of the campfire with turquoise flames. Soul campfires deal more damage than normal campfires. Just like normal campfires, it can be used to cook food, pacify bees, act as a spread-proof light source, smoke signal or damaging trap block.
