If you have reached the limit of my skill and would like to test your power in the present war with the mobs, then I recommend to install mod for Minecraft IncreaseMobs 1.11. A very simple modification by which you can reduce or increase spawn any mob. All settings are in the configuration file!
How to install IncreaseMobs
- Download and install Minecraft Forge
- Download mod
- Do not unzip it, copy to C:\Users\User_Name\AppData\ Roaming\.minecraft\mods
