In "Don't Starve", as long as the character's spiritual value is not enough, after lighting a bonfire, black hands will attack your bonfire, and then the bonfire will become smaller and smaller, eventually causing the bonfire to go out. So how do you keep the black hands away and keep the bonfire burning?

How to drive away the black fire and keep the bonfire alive in "Don't Starve":

Generally, music and black hands appear because the mental value is relatively low.

The black hand will gradually reach towards your campfire (with a weird BGM). If you don't care, it will grab a handful of fire and steal it, making the fire much weaker. If the fire is not strong to begin with or if two hands come at once, it will be extinguished in a flash.

The solution is to light a torch and push the black hand in the direction it is coming from. After chasing it for a while, it will disappear.

Summary: This way the bonfire won't go out and the black hands won't appear.
