Have you ever wanted (Life Steal) like you have seen on java Minecraft? Well if so here's the pack when you kill a player they lose 1 heart and you gain 1 heart. Once you hit 0 hearts you will become a ghost or get banned. And if you don't like some settings almost all of the pack is customizable with an easy-to-use item to open settings and edit them.
