Psionic powers spring from sentient minds. Even an undead creature or a being that has no physical form can create a reserve of inner strength necessary to manifest powers, as long as it has an Intelligence score of at least 1. Vermin possessed of a hive mind ability are an exception to this rule.
A psionic power is a one-time psionic effect. Psionic characters and creatures need not prepare their powers for use ahead of time. They either have sufficient power points to manifest a power or they do not.
A power is manifested when a psionic character pays its power point cost. Some psionic creatures automatically manifest powers, called psi-like abilities, without paying a power point cost. Other creatures pay power points to manifest their powers, just as characters do.
Each power has a specific effect. A power known to a psionic character can be used whenever he or she has power points to pay for it.
Manifesting Powers
Psionic characters and creatures manifest powers. Whether they cost power points when manifest by a psionic character, or are manifested as psi-like abilities, powers’ effects remain the same. The process of manifesting a power is akin to casting a spell, but with significant differences.
Choosing a Power
First you must choose which power to manifest. You can select any power you know, provided you are capable of manifesting powers of that level or higher. To manifest a power, you must pay power points, which count against your daily total. You can manifest the same power multiple times if you have points left to pay for it.
Concentration
To manifest a power, you must concentrate. If something threatens to interrupt your concentration while you’re manifesting a power, you must succeed on a Concentration check or lose the power points without manifesting the power. The more distracting the interruption and the higher the level of the power that you are trying to manifest, the higher the DC. (Higher-level powers require more mental effort.)
Injury: Getting hurt or being affected by hostile psionics while trying to manifest a power can break your concentration and ruin a power. If you take damage while trying to manifest a power, you must make a Concentration check (DC 10 + points of damage taken + the level of the power you’re manifesting). The interrupting event strikes during manifestation if it occurs between when you start and when you complete manifesting a power (for a power with a manifesting time of 1 round or longer) or if it comes in response to your manifesting the power (such as an attack of opportunity provoked by the manifesting of the power or a contingent attack from a readied action).
If you are taking continuous damage half the damage is considered to take place while you are manifesting a power. You must make a Concentration check (DC 10 + 1/2 the damage that the continuous source last dealt + the level of the power you’re manifesting).
If the last damage dealt was the last damage that the effect could deal then the damage is over, and it does not distract you.
Repeated damage does not count as continuous damage.
Power: If you are affected by a power while attempting to manifest a power of your own, you must make a Concentration check or lose the power you are manifesting. If the power affecting you deals damage, the Concentration DC is 10 + points of damage + the level of the power you’re manifesting. If the power interferes with you or distracts you in some other way, the Concentration DC is the power’s save DC + the level of the power you’re manifesting. For a power with no saving throw, it’s the DC that the power’s saving throw would have if a save were allowed.
Grappling or Pinned: To manifest a power while grappling or pinned, you must make a Concentration check (DC 20 + the level of the power you’re manifesting) or lose the power.
Vigorous Motion: If you are riding on a moving mount, taking a bouncy ride in a wagon, on a small boat in rough water, belowdecks in a storm-tossed ship, or simply being jostled in a similar fashion, you must make a Concentration check (DC 10 + the level of the power you’re manifesting) or lose the power.
Violent Motion: If you are on a galloping horse, taking a very rough ride in a wagon, on a small boat in rapids or in a storm, on deck in a storm-tossed ship, or being tossed roughly about in a similar fashion, you must make a Concentration check (DC 15 + the level of the power you’re manifesting) or lose the power.
Violent Weather: If you are in a high wind carrying blinding rain or sleet, the DC is 5 + the level of the power you’re manifesting. If you are in wind-driven hail, dust, or debris, the DC is 10 + the level of the power you’re manifesting. In either case, you lose the power if you fail the Concentration check. If the weather is caused by a power, use the rules in the Power subsection above.
Manifesting Powers on the Defensive: If you want to manifest a power without provoking attacks of opportunity, you need to dodge and weave. You must make a Concentration check (DC 15 + the level of the power you’re manifesting) to succeed. You lose the power points without successful manifestation if you fail.
Entangled: If you want to manifest a power while entangled in a net or while affected by a power with similar effects you must make a DC 15 Concentration check to manifest the power. You lose the power if you fail.
Manifester Level
The variables of a power’s effect often depend on its manifester level, which is equal to your psionic class level. A power that can be augmented for additional effect is also limited by your manifester level (you can’t spend more power points on a power than your manifester level). See Augment under Descriptive Text, below.
You can manifest a power at a lower manifester level than normal, but the manifester level must be high enough for you to manifest the power in question, and all level-dependent features must be based on the same manifester level.
In the event that a class feature or other special ability provides an adjustment to your manifester level, this adjustment applies not only to all effects based on manifester level (such as range, duration, and augmentation potential) but also to your manifester level check to overcome your target’s power resistance and to the manifester level used in dispel checks (both the dispel check and the DC of the check).
Power Failure
If you try to manifest a power in conditions where the characteristics of the power (range, area, and so on) cannot be made to conform, the manifestation fails and the power points are wasted.
Powers also fail if your concentration is broken (see Concentration, above).
The Power’s Result
Once you know which creatures (or objects or areas) are affected, and whether those creatures have made successful saving throws (if any were allowed), you can apply whatever results a power entails.
Special Power Effects
Certain special features apply to all powers.
Attacks: Some powers refer to attacking. All offensive combat actions, even those that don’t damage opponents, such as disarm and bull rush, are considered attacks. All powers that opponents can resist with saving throws, that deal damage, or that otherwise harm or hamper subjects are considered attacks. Astral construct and similar powers are not considered attacks because the powers themselves don’t harm anyone.
Bonus Types: Many powers give creatures bonuses to ability scores, Armor Class, attacks, and other attributes. Each bonus has a type that indicates how the power grants the bonus. The important aspect of bonus types is that two bonuses of the same type don’t generally stack. With the exception of dodge bonuses, most circumstance bonuses, and racial bonuses, only the better bonus works (see Combining Psionic and Magical Effects, below). The same principle applies to penalties—a character taking two or more penalties of the same type applies only the worst one.
Bringing Back the Dead: Of all the psionic powers, only reality revision has the ability to restore slain characters to life. When a living creature dies, its soul departs the body, leaves the Material Plane, travels through the Astral Plane, and goes to abide on the plane where the creature’s deity resides. If the creature did not worship a deity, its soul departs to the plane corresponding to its alignment. Bringing someone back from the dead means retrieving his or her soul and returning it to his or her body.
Level Loss: The passage from life to death and back again is a wrenching journey for a being’s soul. Consequently, any creature brought back to life usually loses one level of experience. The character’s new experience point total is midway between the minimum needed for his or her new (reduced) level and the minimum needed for the next one. If the character was 1st level at the time of death, he or she loses 2 points of Constitution instead of losing a level. This level loss or Constitution loss cannot be repaired by any mortal means, even the spells wish or miracle. A revived character can regain a lost level by earning XP through further adventuring. A revived character who was 1st level at the time of death can regain lost points of Constitution by improving his or her Constitution score when he or she attains a level that allows an ability score increase.
Preventing Revivification: Enemies can take steps to make it more difficult for a character to be returned from the dead. Keeping the body prevents others from using a single manifestation of reality revision to restore the slain character to life.
Revivification Against One’s Will: A soul cannot be returned to life if it does not wish to be. A soul knows the name, alignment, and patron deity (if any) of the character attempting to revive it and may refuse to return on that basis.
Combining Psionic and Magical Effects
The default rule for the interaction of psionics and magic is simple: Powers interact with spells and spells interact with powers in the same way a spell or normal spell-like ability interacts with another spell or spell-like ability. This is known as psionics–magic transparency.
Psionics–Magic Transparency: Though not explicitly called out in the spell descriptions or magic item descriptions, spells, spell-like abilities, and magic items that could potentially affect psionics do affect psionics.
When the rule about psionics–magic transparency is in effect, it has the following ramifications.
Spell resistance is effective against powers, using the same mechanics. Likewise, power resistance is effective against spells, using the same mechanics as spell resistance. If a creature has one kind of resistance, it is assumed to have the other. (The effects have similar ends despite having been brought about by different means.)
All spells that dispel magic have equal effect against powers of the same level using the same mechanics, and vice versa.
The spell detect magic detects powers, their number, and their strength and location within 3 rounds (though a Psicraft check is necessary to identify the discipline of the psionic aura).
Dead magic areas are also dead psionics areas.
Multiple Effects: Powers or psionic effects usually work as described no matter how many other powers, psionic effects, spells, or magical effects happen to be operating in the same area or on the same recipient. Except in special cases, a power does not affect the way another power or spell operates. Whenever a power has a specific effect on other powers or spells, the power description explains the effect (and vice versa for spells that affect powers). Several other general rules apply when powers, spells, magical effects, or psionic effects operate in the same place.
Stacking Effects: Powers that provide bonuses or penalties on attack rolls, damage rolls, saving throws, and other attributes usually do not stack with themselves. More generally, two bonuses of the same type don’t stack even if they come from different powers, or one from a power and one from a spell. You use whichever bonus gives you the better result.
Different Bonus Types: The bonuses or penalties from two different powers, or a power and a spell, stack if the effects are of different types. A bonus that isn’t named (just a “+2 bonus” rather than a “+2 insight bonus”) stacks with any bonus.
Same Effect More than Once in Different Strengths:** In cases when two or more similar or identical effects are operating in the same area or on the same target, but at different strengths, only the best one applies. If one power or spell is dispelled or its duration runs out, the other power or spell remains in effect (assuming its duration has not yet expired).
Same Effect with Differing Results: The same power or spell can sometimes produce varying effects if applied to the same recipient more than once. The last effect in a series trumps the others. None of the previous spells or powers are actually removed or dispelled, but their effects become irrelevant while the final spell or power in the series lasts.
One Effect Makes Another Irrelevant: Sometimes, a power can render another power irrelevant.
Multiple Mental Control Effects: Sometimes psionic or magical effects that establish mental control render one another irrelevant. Mental controls that don’t remove the recipient’s ability to act usually do not interfere with one another, though one may modify another. If a creature is under the control of two or more creatures, it tends to obey each to the best of its ability, and to the extent of the control each effect allows. If the controlled creature receives conflicting orders simultaneously, the competing controllers must make opposed Charisma checks to determine which one the creature obeys.
Powers and Spells with Opposite Effects: Powers and spells with opposite effects apply normally, with all bonuses, penalties, or changes accruing in the order that they apply. Some powers and spells negate or counter each other. This is a special effect that is noted in a power’s or spell’s description.
Instantaneous Effects: Two or more magical or psionic effects with instantaneous durations work cumulatively when they affect the same object, place, or creature.
Powers and Power Points
Psionic characters manifest powers, which involve the direct manipulation of personal mental energy. These manipulations require natural talent and personal meditation. A psionic character’s level limits the number of power points available to manifest powers. A psionic character’s relevant high score might allow him to gain extra power points. He can manifest the same power more than once, but each manifestation subtracts power points from his daily limit. Manifesting a power is an arduous mental task. To do so, a psionic character must have a key ability score of at least 10 + the power’s level.
Daily Power Point Acquisition: To regain used daily power points, a psionic character must have a clear mind. To clear his mind, he must first sleep for 8 hours. The character does not have to slumber for every minute of the time, but he must refrain from movement, combat, manifesting powers, skill use, conversation, or any other demanding physical or mental task during the rest period. If his rest is interrupted, each interruption adds 1 hour to the total amount of time he has to rest to clear his mind, and he must have at least 1 hour of rest immediately prior to regaining lost power points. If the character does not need to sleep for some reason, he still must have 8 hours of restful calm before regaining power points.
Recent Manifesting Limit/Rest Interruptions: If a psionic character has manifested powers recently, the drain on his resources reduces his capacity to regain power points. When he regains power points for the coming day, all power points he has used within the last 8 hours count against his daily limit.
Peaceful Environment: To regain power points, a psionic character must have enough peace, quiet, and comfort to allow for proper concentration. The psionic character’s surroundings need not be luxurious, but they must be free from overt distractions, such as combat raging nearby or other loud noises. Exposure to inclement weather prevents the necessary concentration, as does any injury or failed saving throw the character might incur while concentrating on regaining power points.
Regaining Power Points: Once the character has rested in a suitable environment, it takes only an act of concentration spanning 1 full round to regain all power points of the psionic character’s daily limit.
Death and Power Points: If a character dies, all daily power points stored in his mind are wiped away. A potent effect (such as reality revision) can recover the lost power points when it recovers the character.
Adding Powers
Psionic characters can learn new powers when they attain a new level. A psion can learn any power from the psion/wilder list and powers from his chosen discipline’s list. A wilder can learn any power from the psion/wilder list. A psychic warrior can learn any power from the psychic warrior list.
Powers Gained at a New Level: Psions and other psionic characters perform a certain amount of personal meditation between adventures in an attempt to unlock latent mental abilities. Each time a psionic character attains a new level, he or she learns additional powers according to his class description. Psions, psychic warriors, and wilders learn new powers of their choice in this fashion. These powers represent abilities unlocked from latency. The powers must be of levels the characters can manifest.
Independent Research: A psion also can research a power independently, duplicating an existing power or creating an entirely new one. If characters are allowed to develop new powers, use these guidelines to handle the situation.
Any kind of manifester can create a new power. The research involved requires access to a retreat conducive to uninterrupted meditation. Research involves an expenditure of 200 XP per week and takes one week per level of the power. At the end of that time, the character makes a Psicraft check (DC 10 + spell level). If that check succeeds, the character learns the new power if her research produced a viable power. If the check fails, the character must go through the research process again if she wants to keep trying.
Manifest an Unknown Power from Another’s Powers Known
A psionic character can attempt to manifest a power from a source other than his own knowledge (usually a power stone or another willing psionic character). To do so, the character must first make contact (a process similar to addressing a power stone, requiring a Psicraft check against a DC of 15+ the level of the power to be manifested). A psionic character can make contact with only a willing psionic character or creature (unconscious creatures are considered willing, but not psionic characters under the effects of other immobilizing conditions). Characters who can’t use power stones for any reason are also banned from attempting to manifest powers from the knowledge of other psionic characters. Mental contact requires 1 full round of physical contact, which can provoke attacks of opportunity. Once contact is achieved, the character becomes aware of all the powers stored in the power stone or all the powers the other character knows up to the highest level of power the contactor knows himself.
Next, the psionic character must choose one of the powers and make a second Psicraft check (DC 15 + the power’s level) to see if he understands it. If the power is not on his class list, he automatically fails this check.
Upon successfully making contact with another willing psionic character or creature and learning what he can of one power in particular, the character can immediately attempt to manifest that power even if he doesn’t know it (and assuming he has power points left for the day). He can attempt to manifest the power normally on his next turn, and he succeeds if he makes one additional Psicraft check (DC 15 + the power’s level). He retains the ability to manifest the selected power for only 1 round. If he doesn’t manifest the power, fails the Psicraft check, or manifests a different power, he loses his chance to manifest that power for the day.
Using Stored Power Points
A variety of psionic items exist to store power points for later use, in particular a storage device called a cognizance crystal. Regardless of what sort of item stores the power points, all psionic characters must follow strict rules when tapping stored power points.
A Single Source: When using power points from a storage item to manifest a power, a psionic character may not pay the power’s cost with power points from more than one source. He must either use an item, his own power point reserve, or some other discrete power point source to pay the manifestation cost.
Recharging: Most power point storage devices allow psionic characters to “recharge” the item with their own power points. Doing this depletes the character’s power point reserve on a 1-for-1 basis as if he had manifested a power; however, those power points remain indefinitely stored. The opposite is not true—psionic characters may not use power points stored in a storage item to replenish their own power point reserves.
