@Ace of flames01 Wraiths are just vengeful spirits they're similar to reapers, but whilst reapers are typically a cause of death a wraith is just drawn to a death. They tend to act as sign of death to come or arrive after a death has occurred.
However, they're still incorporeal. Your description of a reaper suggested they could be touched, wraiths are still spirits and can't be touched except with magical items or by other spirits.
The weapon I'm not sure how to work with it really, lore maintains that wraiths wield ghostly blades that can still trike mortal men low. How do you recommend incorporating that without making it too powerful?
