AdaptiveMobs

to support me you can download from linkvertise: https://link-hub.net/1293061/adaptivemob-plugin-minecr               also yes it called minecr I couldn't make it fit with only 20 letters                                                                     

• /mob optimize - Automatically optimizes settings based on server load
• /mob status - Shows current memory usage and mob statistics
• /mob features <crafting|building|pathfinding> <on|off> - Toggle specific features      /mob` command for server performance optimization and status checks, improving server management capabilities.

Basically this is a mod that makes it that mobs such as zombies adapt to what you do meaning if your craft something in front of them they will adapt and craft to if you mine front of them they will adapt to and mine and if you place blocks they will place  if you build up high the zombie will adapt to that mine blocks and build up high to kill you basically it can adapt to your every move and find a way to kill the player this is really cool plugin for like earth servers and friend server if you want to support me you can download this from linkvertise but yes this is a fun mod and this mod is only like 39kb of a file so it wont lag servers but if it does their a /mob  command and even if it does you can download my other mod that reduces lag tps reduce disk storage and CPU usage https://www.curseforge.com/minecraft/bukkit-plugins/serverfps and yes free advertise I just did right their
