The Preta is the ghost of someone who has died of thirst, and continues on into death to slake it. Shrunken and tattered they are accompanied by a hot biting wind that whistles about their blackened bodies. When a Preta comes close, water dries in its containers, throats become parched and rivers fail. The touch of a Preta drains all the moisture from a living creature, and it will run madly towards anything that it can consume with thirst in its mad eyes. A more dangerous attack, however, is the Preta's Thirsty Breath. The Preta opens its unhinged jaw and a desiccating tornado of wind rushes into its body, sucking moisture from whatever it touches. The Preta heals 1 Health for each 5 weakening it inflicts in this way.
Like most embodied undead the Preta is resistant to normal weapons, taking half damage from physical attacks and spells. Sacred weapons, ice and water based attacks, and attacks made using living weapons (natural weapons, barehanded attacks, living wood) do normal damage. Immersing a Preta in open water deals D10 damage a round.
