This data pack is inspired by Atomic Stryker's legendary Infernal Mobs mod.
Configure the Pack
Many aspects of this data pack can be configured by simply changing some score values.
You can access a chat based configuration menu while ingame by running the command /function ps-mob:config if you have operator permissions.
Set the scoreboard values of the ps-mob.config scoreboard to your desired values!
