A psicrystal weapon is a fragment of a psionic character’s personality, brought into physical form and a semblance of life (via the Psicrystal Weapon feat). A psicrystal weapon can appear in the form of any kind of weapon, albeit of a crystalline nature. Because it is an extension of its creator’s personality, a character’s psicrystal weapon is in some ways a part of him. That’s why, for example, a psionic character can manifest a touch power through his weapon, rather than through his own hands.
To have a psicrystal weapon, you need the Psicrystal Weapon feat.
Interaction with Psicrystals
You cannot transform an existing normal psicrystal or psicrysmal into a psicrystal weapon, but you can transform a normal crystal or deep crystal weapon into a psicrystal weapon by taking the Psicrystal Weapon feat.
A psicrystal weapon is treated as a construct for the purposes of all effects that depend on its type. A psicrystal weapon grants special abilities to its owner, as shown on the Psicrystal Weapon Special Abilities table below. Psicrystal weapon abilities are based on the owner’s levels in psionic classes (any class which grants power points or psi-like abilities). Levels from other classes do not count toward the owner’s level for purposes of psicrystal abilities. A psicrystal weapon can speak one language of its owner’s choice (so long as it is a language the owner knows). A psicrystal weapon can understand all other languages known by its owner, but cannot speak them. This is a supernatural ability.
A psicrystal weapon is treated as a masterwork weapon made out of crystal, as well as a construct. For the purposes of powers, spells, weapon maneuvers (disarm, sunder, etc.) and enchanting the psicrystal weapon, it counts as a masterwork weapon if applicable (some spells, such as shatter, affect only items). For all other purposes, it counts as a creature - so you can disarm the weapon and sunder it, or enchant it, as well as use a power which only targets constructs, such as psionic repair damage.
Psicrystal Weapon Basics
Use the statistics for a psicrystal, but make the following changes.
Hit Dice: For the purpose of effects related to number of Hit Dice, use the owner’s character level.
Hit Points: The psicrystal weapon has one-half of its owner’s total hit points (not including temporary hit points), rounded down, regardless of its actual Hit Dice.
Abilities: The psicrystal weapon has Intelligence 10, Wisdom 10, and Charisma 10.
Skills: The psicrystal weapon cannot use any skills except for Spot, Listen and Search (but only for noticing secret doors) at which time it uses its master’s skill ranks and its own ability modiﬁer.
Psicrystal Weapon Special Abilities
All psicrystal weapons have special abilities (or impart abilities to their owners) depending on the level of the owner, as shown on Table 3 - The Psicrystal Weapon. The abilities on the table are cumulative.
Hardness Adj. (Ex): This number noted here is an improvement to the weapon’s normal hardness. It represents the infusion of a psicrystal’s preternatural durability into the weapon’s form.
Intelligence Adj. (Ex): Add this value to the psicrystal weapon’s Intelligence score. Psicrystal weapons are as smart as people (though not necessarily as smart as smart people).
Sighted (Ex): Although it has no physical sensory organs, a psicrystal weapon can telepathically sense its environment as well as a creature with normal vision and hearing. Darkness (even supernatural darkness) is irrelevant, as are areas of supernatural silence, though a psicrystal weapon still can’t discern invisible or ethereal beings. A psicrystal weapon’s sighted range is 40 feet.
Telepathic Link (Su): The owner has a telepathic link with his psicrystal weapon out to a distance of up to 1 mile. The owner cannot see through the psicrystal weapon’s senses, but the two of them can communicate telepathically as if the psicrystal weapon were the target of a mindlink power manifested by the owner. For instance, a psicrystal weapon placed in a distant room could relay the activities occurring in that room. Because of the telepathic link between a psicrystal weapon and its owner, the owner has the same connection to an item or place that the psicrystal weapon does. For instance, if his psicrystal weapon has seen a room, the owner can teleport into that room as if he has seen it too.
Empathic Link (Su): The owner has an empathic link with his psicrystal weapon whenever he has physical contact with it and is psionically focused. Whenever he fulﬁlls these conditions he gains a +2 bonus to one skill of his choice, chosen when he ﬁrst gains access to this ability.
Deliver Touch Powers (Su): If the owner is 3rd level or higher, his psicrystal weapon can deliver touch powers for him. If the owner holds his psicrystal weapon in his hand at the time he manifests a touch power, he can designate his psicrystal as the “toucher.” The psicrystal weapon can then deliver the touch power just as the owner could. As usual, if the owner manifests another power before the touch is delivered, the touch power dissipates.
Telepathic Speech (Ex): If the owner is 5th level or higher, the psicrystal weapon can communicate telepathically with any creature that has a language and is within 30 feet of the psicrystal weapon, while the psicrystal weapon is also within 1 mile of the owner.
Deep Crystal (Ex): If the owner is 9th level or higher, the psicrystal weapon has become hardened from the exposure to psionic energy. It changes type from crystal to deep crystal, gaining a higher hardness value (reﬂected in the table above) and the ability to channel psionic energy. As a free action that does not provoke attacks of opportunity, the owner can channel psionic power into his psicrystal weapon. For 2 power points, the psicrystal weapon deals an extra 2d6 points of damage. The weapon will stay charged for 1 minute or until it scores its next hit. Bows and crossbows bestow this power on their ammunition. All missile weapons lose this effect if they miss. However, they may be recovered and charged again. If the weapon was already made out of deep crystal, it deals an additional +1d6 damage when its owner achieves 9th level.
Power Resistance (Ex): If the owner is 11th level or higher, the psicrystal weapon gains power resistance equal to the owner’s level + 5. To affect the psicrystal weapon with a power, another manifester must get a result on a manifester level check that equals or exceeds the psicrystal weapon’s power resistance.
Material Mastery (Su): If the owner is 15th level or higher, he can change how his psicrystal weapon behaves in relation to damage reduction. As a free action that does not provoke attacks of opportunity, the owner can spend 2 power points to change his psicrystal weapon. Choose Adamantine, Silver, or Cold Iron, the weapon will penetrate damage reduction as if it was made out of this material for 1 minute.
