Minecraft Dungeons:Mob Spawner

The Mob Spawner is an uncommon monster factory that spawns mobs $$.

Spawning
The mob spawner can be found within the Redstone Mines and the Fiery Forge.

Behavior
Mob spawners behave in a similar vein to the core game, but light doesn't affect the spawn rate. Mobs are produced in huge waves whenever the player is within a certain distance from it.

Trivia

 * Even though the Spawner itself does not move, the Gravity enchantment can cause it to.
