LoTRO Lord of the Rings Online Shade
Once men from ages past, these spirits are held to the Earth by an ancient curse. Their ethereal bodies and deadly attacks make them extremely difficult to conquer through traditional means. But a shade seeks vengeance, or redemption, or release, so it may serve a willing adventurer better to aid the shade’s exit from this world than to try and fight through them.
These beings are modeled on the Oath-breakers Aragon enlisted on the Path of the Dead. Remember that they will kill any who oppose them, but aid the adventurer who promises to end their suffering.
