The Stranger will spawn in your world and slowly get closer and closer. Running up to him could either make him disappear or run right back at you! You can throw molotov cocktails at him to set him on fire.
This is my first horror mod ever, just to see what it's like. I have a bigger and BETTER horror mod planned!
Put this in your horror modpacks for a little extra horror, or just for the molotovs. :)
