Monster Spawner

Monster Spawner
The Default Monster Spawner without any mob

The Monster Spawner is able to spawn mobs of a particular type making it fairly useful for farms and other mechanics that require an abundance of mobs. The Spawner is obtainable as an item in both Java Edition and Bedrock Edition and can be modified with spawn eggs in the Java Edition. With the Monster Spawner being a block entity there are a variety of discontinued NBT variants obtainable. For more information on monster spawners check out the minecraft wiki.
