The ekimmu gives its host many of its undead powers: immunity to sleep, charm, hold, paralysis, cold-based spells and poison. However, it (and its host) takes 2d4 points of damage from a vial of holy water. A protection from evil spell will block its possession attack. A dispel evil exorcises it from its host and gives the host immunity as if a successful saving throw had been made. A holy word immediately exorcises all ekimmu in its area and drives them away, ending the encounter.
If the characters cn find the remains of the ekimmu and give it a proper burial, the ekimmu will dissipate, abandoning any host it controls.
As long as its remains are unburied, a dissipated ekimmu will eventually reform, though this may take some days or weeks.
magic jar said:If you are successful, your life force occupies the host body, and the host’s life force is imprisoned in the magic jar. You keep your Intelligence, Wisdom, Charisma, level, class, base attack bonus, base save bonuses, alignment, and mental abilities. The body retains its Strength, Dexterity, Constitution, hit points, natural abilities, and automatic abilities. A body with extra limbs does not allow you to make more attacks (or more advantageous two-weapon attacks) than normal. You can’t choose to activate the body’s extraordinary or supernatural abilities. The creature’s spells and spell-like abilities do not stay with the body.
