A Specter shown wearing no armor.

The Specter is a hostile mob that is found in Better Dungeons castles between 4000-5000 meters away from the World Spawn. Specters may appear equipped with any type of Vanilla Minecraft weapons or armor. They may also carry one of the many weapons from the Better Dungeons mod like a dagger, healing staff or grenades. The type of weapons and armor a specter has determines it's Class and makes it use different tactics in battle. Specters are ghosts and they look like a translucent version of the default Minecraft player skin that is commonly known as Steve. Specters can be stored and transported in capsules.

Specters belong to the Zombie Faction which also includes Skeletons and Zombies. Specters will attack mobs that belong to a different faction but will not attack members of their own faction. It is possible, by use of commands, to join the Zombie Faction so that the Specters and their allies will follow you and fight for you. The Boss mob of the Specters is the Specter Lord.
