Lava Pit

A lava pit is a new feature added in the 'Hungry for your Hunger' update. It naturally spawns in caves, usually on rocky turf and around stalagmites.

Use
When destroyed with a hammer, the lava pit will emit light, like a campfire, and slowly rebuild itself until there is no light left. The player can then just hammer it again to get more light. This is a renewable light source, like a campfire, but the player needs to keep making hammers, if they want to set up a camp near one. In addition, it is possible that this will set the player alight when too close - the Chilled Amulet might be used to stop this.
