The missing template can be added to any corporeal creature to represent a creature with innate displacement and invisibility abilities. Such creatures might be the result of arcane experimentation by mad wizards, represent a new type of magical creature, or be the result of a mystic accident when creatures are exposed to powerful planar energies.
Type: If the creature is an animal, it becomes a magical beast. If it is a humanoid, it becomes a monstrous humanoid. Do not change the base creature’s statistics to represent the new type. All other creatures retain the type of the base creature.
Even when visible, the missing creature appears to be about 2 feet away from its true location. The creature benefits from a 50% miss chance as if it had total concealment.
A missing creature can avoid even magical and unusual attacks with great agility. If it makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, it instead takes no damage. A helpless missing creature does not gain the benefit of evasion.
Whenever the creature does not attack for 1 full round, it becomes invisible (as the spell) as a free action. In addition to becoming visible if it attacks, the missing creature becomes visible if it takes hit point damage. If made visible by this second method, the missing creature becomes invisible again at the beginning of its next turn (though it might immediately become visible by attacking on that turn).
