Edimmu

An Edimmu is the thirsty shade of someone who died without proper burial or offerings. It enters houses through cracks, drains warmth from sleepers, and fouls stored water with the dust of its abandoned grave. Its face remains recognizable beneath a skin of windblown earth. Food and drink calm it only when offered in the dead person's name.

Grave Thirst: necrotic, melee 5 ft, +3 to hit, 1d8+3. A hit also prevents the target from recovering HP until it drinks clean water offered by another creature.

Funerary Portion: water and bread placed at its remains suppress Grave Thirst and lower its DR to 0. Completing the burial ends the Edimmu permanently.
