This schematic modifies lots of mobs and changes some rules to make your survival world harder. It gives mob lots of buffs and gives you lots of debuffs, it also makes you cannot place torches and iron doors. All of the mobs has special abilities like summon in other mobs and duplicate. The special part of this schematic is that almost all of the commands blocks has signs that tells you what the command does, so you can maybe learn something from these commands easier.Also, this is my first command project, so it may not be perfect.If you find a bug, you can reply down.I may not fix it because I think this command is to hard and a bug maybe can make it easier.
You can use it in 1.9 snapshots and 1.9.
If you want me to make a one command version, reply below.
