Ema spawners are types of spawners that allow you to add up to 54 EMA eggs and it will automatically randomize between all of the eggs you add and spawn that mob with that mob id's attributes. To create an EMA spawner you have to first have ema enabled using /ema enable and you must also have the permission node: ema.spawners. If all of this is true, you can create an EMA spawner or edit the inventory of an already existing EMA spawner by right clicking with the wand, which is a bone. Once you have done this you can set the different attributes of this spawner by looking at it, and typing different commands listed on the main page.
