Looking like a large, strangely proportioned centipede, this symbiont lays itself along the top of the skull. Between a series of soft chitinous plates you can see what looks like brain matter pulsating gently. This is your last thought as a wheel of energy lashes out from it, passing through you, racking your mind with earth shattering pain.

The Psi-biont is a symbiont that is frequently used by psionic individuals in order to broaden their selection of manifest-able powers, and by the non-psionics to grant them psionic power. It is known for being quite inquisitive, and prone to probing into the minds of others to learn more, particularly of the more 'private' aspects of ones mind.
A Psibiont doesn't speak any language, but it understands undercommon.

Combat
A Psibiont can attach itself to only a willing or helpless host (as a full-round action). In general, a potential host seeks out a Psibiont to gain its benefits. It can attach itself to the head, and occupies the head slot.
Attaching or removing a psibiont deals 1d4 of Wis damage.
Host Benefit:

• Psionic Manifestation (Ex): The Symbiont starts off with 2 to 3 random Psion Powers or 1 to 2  Psionic Warrior Powers, determined by its manifester level. Unless otherwise stated, it cannot learn any new powers. Its manifester level is equal to its hit dice plus 1; It uses this Manifester level for casting unless the host is higher. A Psiobiont can hold its own Psionic Focus.

• Psionic Connection (Ex): While attached, a host may use the symbiont's powers as if they were the caster via the shared powers aspect of the Symbiont Traits. They must follow the standard rules for manifesting powers.

• Bonus PP (Ex): The symbiont gains bonus PP based on their Int Score. If the host does not have any psionic class levels than the symbiont gains the potential bonus PP that the host would have if they were a level 1 Psion or Psionic Warrior.

• Symbiont Traits :  

• Telepathy (Su) : The symbiont can communicate telepathically with its host, if its host has a language.

Having seen many breasts, you know that the breasts of the woman before you are not normal by any stretch of the imagination. The skin is a deep blue as if consumed by frostbite. Bits of ice surround the nearly black nipples that jut out like the icicles that hang from the undersides of those disturbing mounds. Latched onto each breast are some sort of fiendish conjoined starfish of similar coloration.

It is unknown who is exactly responsible for the creation of this particular symbiont, what is known is that they were as cold as the ice that their symbionts create. The cold nature of the Witch's Tit is shared by its personality, which results in few people usually seeking one out. Even those who live in cold environments generally don't bother with them unless they must; in such cases they are a useful companion.

Combat
A Witch's Tit can attach itself to only a willing or helpless host (as a full-round action). In general, a potential host seeks out a Witch's Tit to gain its benefits. It can attach itself to the breasts of a host, taking up the chest slot.
Attaching or removing a Witch's Tit deals 1d4 of Dex damage.
Host Benefit:

• Icy Tolerance (Ex): The host gains 1 Cold Resistance for every 20lbs of breast weight. The host can also exist comfortably at icy temperatures.

• White Ice Spray (Su):  The icy nature of the symbiont reaches into the very core of your body so that even your milk is affected. As a standard action you may unleash two jets of frozen milk as a ranged touch attack with a range of 20ft, and requires the spending of 2 Milk Points. The shards deal 1d6 cold damage plus 1 for every extra Milk point. You may spend a number of extra milk points equal to your Con Modifier plus the Symbionts Con Modifier.

• Cold Temperament: This symbiont is known for being cold towards others, sometimes even its host. It receives a +2 to its ego score.

• Symbiont Traits

• Telepathy (Su) : The symbiont can communicate telepathically with its host, if its host has a language.
