Mob Grinders Are Allowed
But there are some rules you must follow.
1 – You must provide a player with a /pwarp to your grinder and allow players access to at lease 1 storage chest or access to the item drops.
2 – Keep your grinders under control so that it does not lag the system, If a grinder is found affecting the server we will try to resolve the issue with you. Before the racking crew in called in.
3 – Post your /pwarp under the Grinders Category.
To help players with building grinders you can use spawners.
Example : iron golem spawners can be used in place of Villager type of iron farm.
If you are real lucky you can win a spawner using the Crate Keys or just visit the PMS shop. /pms
