Campfires

The Campfire is a three-block wide device. When standing near a Campfire, a player's health regeneration is increased. This mechanic makes it a worthy addition to boss arenas. It is probably smart to have one of these in your hotbar when going spelunking or into a dangerous place so that you can place it down quickly for some fast regeneration. It gives off a low amount of red light and smoke. Campfires also work underwater. It is also used to cook a Marshmellow on a Stick.
