A spirit companion can be an elemental, a nature spirit or the departed soul of a humanoid or monstrous humanoid. Regardless of the nature of the spirit companion, they all share certain characteristics, represented by the Spirit Companion template (below).

If a spirit companion is destroyed or otherwise leaves the service of the intuitive, the intuitive loses all class abilities until they regain a spirit companion, usually through a three day session of meditation and fasting.

At first level, the Intuitive may have a spirit companion with an ECL of 1.

An Intuitive can only bond a combined total ECL worth of spirit companions as presented in the table below:

Advancing a Spirit Companion
Whenever the Intuitive’s Maximum Total ECL of spirit companions increases, she may choose to advance an existing spirit companion. If the spirit companion has an Intelligence score greater than 3, it may advance by character class. Otherwise, it advances as an undead.

Calling a New Spirit Companions
Whenever the Intuitive’s Maximum Total ECL of spirit companions increases, she may choose to gain a new spirit companion. Doing so requires a full day of meditation. At the end of this meditation, a new spirit companion appears. This new spirit companion has an ECL of 1. If the spirit companion has an Intelligence score greater than 3, it may advance by character class. Otherwise, it advances as an undead.

Replacing a Spirit Companion
Whenever the Intuitive’s Maximum Total ECL of spirit companions increases or she has lost her spirit companion for whatever reason, she may choose to undergo a ritual to summon (or bond in the case of an Intuitive encountering a suitable spirit) a replacement. This ritual involves three days of fasting and meditation after which the new companion appears. The new spirit companion has the same ECL as the replaced companion.

Spirit Companion Template
Spirit companion is an acquired template that can be applied to any non-undead, non-construct creature with an intelligence score.

Size and Type
The creature’s type changes to undead. It gains the incorporeal subtype. Size is unchanged.

Hit Dice
Hit Dice becomes d12’s. For effects that depend on number of HD, use the intuitive’s character level or the spirit companion’s HD, which ever is higher.

Speed
Spirit Companions have a fly speed of 30 feet, unless the base creature has a higher fly speed, with perfect maneuverability.

Ability Scores
Cha becomes 8 if not already 8 or higher.

Armor Class
Natural armor is the same as the base creature’s but applies only to ethereal encounters. When the spirit companion manifests (see below), its natural armor bonus is +0, but it gains a deflection bonus equal to its Charisma modifier or +1, whichever is higher.

Attack
A spirit companion retains all the attacks of the base creature, although those relying on physical contact do not affect creatures that are not ethereal.

Full Attack
A ghost retains all the attacks of the base creature, although those relying on physical contact do not affect creatures that are not ethereal.

Damage
Against ethereal creatures, a spirit companion uses the base creature’s damage values. Against non-ethereal creatures, the spirit companion usually cannot deal physical damage at all but can use its special attacks, if any, when it manifests (see below).

Special Attacks and Qualities
A spirit companion retains all the special attacks of the base creature, although those relying on physical contact do not affect non-ethereal creatures. The spirit companion also gains the following abilities.

Manifestation (Su): A spirit companion dwells on the Ethereal Plane and, as an ethereal creature, it cannot affect or be affected by anything in the material world. When a spirit companion manifests, it partly enters the Material Plane and becomes visible but incorporeal on the Material Plane. A manifested spirit companion can be harmed only by other incorporeal creatures, magic weapons, or spells, with a 50% chance to ignore any damage from a corporeal source. A manifested spirit companion can pass through solid objects at will, and its own attacks pass through armor. A manifested spirit companion always moves silently. A manifested spirit companion can strike with ghost touch weapon. A manifested spirit companion remains partially on the Ethereal Plane, where is it not incorporeal. A manifested spirit companion can be attacked by opponents on either the Material Plane or the Ethereal Plane. The spirit companion’s incorporeality helps protect it from foes on the Material Plane, but not from foes on the Ethereal Plane.

When a spellcasting spirit companion is not manifested and is on the Ethereal Plane, its spells cannot affect targets on the Material Plane, but they work normally against ethereal targets. When a spellcasting spirit companion manifests, its spells continue to affect ethereal targets and can affect targets on the Material Plane normally unless the spells rely on touch. A manifested spirit companion’s touch spells don’t work on non-ethereal targets.

A spirit companion has two home planes, the Material Plane and the Ethereal Plane. It is not considered extraplanar when on either of these planes.

A spirit companion can only remain manifested for 1 minute each day per Intuitive level of the intuitive it is bound with. This time does not need to be contiguous.

Bound (Ex): A spirit companion is mystically bound to their intuitive. If they ever move out of a range equal to 20ft per intuitive level, they lose all turn immunity and the ability to manifest. These advantages return when they return to that range.

Mistreated spirit companions can choose to leave their intuitives, denying that character spells and class abilities until such time as they gain a new spirit companion.

Telepathic Link (Su): A spirit companion and their intuitive share a telepathic link out to a distance of 20ft / intuitive level. The intuitive cannot see through the companion’s eyes, but they can communicate verbally.

Because of the nature of this link, the intuitive has the same connection to an item or place as their companion does.

Turn Immunity (Ex): Spirit companions are immune to the effects of turn or rebuke attempts.

Speak with Spirits (Su): A spirit companion gains the ability to speak with other creatures like itself, which includes elementals, incorporeal undead, creatures in astral form, and fey.
