Harriken (Headsnatcher Fiend)

A harriken can detach its head from its body and replace it with the decapitated head of any humanoid creature. In so doing, it can assume the dead creature's form.

To kill a harriken, one must destroy its head. While wearing the head and assuming the form of another creature, a harriken will usually entrust its detached head to loyal underlings or hide it somewhere safe.

Attach Head (Ex): As an attack or move action, a harriken can attach a head (either its own detached head or the severed head of any Medium-size humanoid creature) to its headless body. It gains the visual, auditory, and olfactory senses of the creature whose head it wears; if the creature had low-light vision, for instance, the harriken gains this ability for as long as the head is worn.

The creature from which the head is taken must have died within the past 24 hours; otherwise, any attempt by the harriken to graft the head onto its body fails.

Body Blindsight (Ex): A harriken's headless body can sense its surroundings as though it has the blindsight ability with a range of 30 feet. However, without its own head, the harriken loses its darkvision.

Detach Head (Ex): As an attack or move action, a harriken can detach the head (either its own head or the severed head of any Medium-size humanoid creature) from its body.

Disguise Self (Su): The harriken can assume the appearance of a specific Medium-size humanoid creature by attaching the creature's severed head to its body. The illusion lasts as long as the head remains attached. The harriken does not gain any of the creature's abilities, mannerisms, or knowledge, but it gains a +10 bonus on Disguise checks. Other creatures get a Will save (DC 10 + 1/2 the harriken's Hit Dice + its Charisma modifier) to pierce the illusion if they interact with it (such as by touching the harriken and having that sensory input not match what they see). A true seeing spell reveals the harriken's actual horrific appearance.

Electrical Rejuvenation (Ex): A harriken is immune to electricity. Furthermore, it heals 1 point of damage for every die of electricity damage it would take normally. For example, a 6d6 lightning bolt heals 6 points of damage to the harriken.

Fire Resistance 10 (Ex): A harriken ignores the first 10 points of damage from any attack that deals fire damage.

Indestructible Body (Su): While its head is attached to its body, a harriken can be killed. However, if its head is detached, the body stops taking damage when reduced to 1 hit point. Any damage dealt to the body that would knock it below 1 hit point is ignored. If the harriken's detached head is found and destroyed (Defense 7; hp 5), the harriken's body is instantly slain.

Telepathy (Su): A harriken can communicate telepathically with any creature within 100 feet that has a language.
