Ghosts

For the mob in the Dwarven Mines, see Ghost  is a Dungeon mechanic that when you die in a dungeon, you become a ghost. While you are a ghost, you can fly around the dungeon but cannot interact with anything except for killing fairies to revive yourself. If you enter a new room as a ghost, it won't appear in the magical map.

Ghosts cannot attack dungeon mobs with the exception of their Ghost Abilities. For additional ghost abilities you can get the Spirit Sword and Spirit Bow which appears in your inventory when you are dead.
