Abnormals are mobs that don't quite fit into any tier. They're easily the most diverse tier, as the mobs in it have almost nothing in common. They all spawn in different ways and share nearly nothing in common. They range a lot in power and unique abilities. There are a total of seventeen mobs in this tier.
