The butterflies are spread through either one butterfly touching a person or skin to skin contact with an infected there are only two ways of curing oneself either through cutting the tattoo off the skin or through burning it off such as a lighter but this can only last only through the two days of infection as of phase two the butterfly tattoo will appear to be marking the veins of its victim spreading its influence to Phase three where the infected starts showing erratic behavior trying to infect as many as possible grabbing people by the hand going into fist fights even causing riots with high population areas such as prison. The next phase of the infection skin will be covered in the color of the butterfly that infected them even their eyes seemingly tattooed with only the pupils being seen and the last and final phase where the infected skin will take on chrysalis like texture after taking all their clothing off and lastly hugging their knees to take on a ball like appearance when this is done a large insect will break out of the former human in less then a few minutes these entities seem to be non sentient and hostile attacking any human they can these also carry the infect but once they are killed their gaster will pop releasing hundred of butterflies spreading the infect luckily the infection Only affects humans and the majority of these are eaten by natural predators of butterflies flame throwers help as well.
