This addon adds 14 new hostile mobs that evolve over time and 3 new weapons.
The weakest new mob is a buglin, which spawns in darkness and transforms into a rupter after a few minutes. The rupter is able to infect nearby pigs, cows, rabbits, chickens, horses, villagers, and sheep. All of these mobs will transform into living flesh after a few minutes. Living flesh can evolve into one of 5 random mobs if they merge with an infected mob. These 5 mobs are very powerful and can drop rare items used to craft the new weapons.
