When you choose this discipline at 1st level, you learn the imbue psicrystal talent. This talent does not count against the number of psion talents you know.

Beginning at 1st level, you may start with an arcane focus crystal, described in the Player’s Handbook. This crystal fulfills the material component requirement of the imbue psicrystal talent. This counts as one of your two items.

At 2nd level, you learn the project eidolon augment. This does not count against the number of psion augments you know.

When you manifest project eidolon, you may reduce its minimum psi cost to 2. If you do, project eidolon augments imbue psicrystal as a 1st level power, and you manifest a weaker version of the basic eidolon. The eidolon you create is Small, has an AC of 12, has a hit point maximum of 5, a -2 penalty on attack and damage rolls, and you do not select any abilities from the Lesser Eidolon Ability menu to apply to the eidolon for free. (These adjustments are included in the “Shaper’s 1st Level Eidolon” stat block in Chapter 5: Psionic Monsters).

Also at 2nd level, you select one type of psychic matter to draw from when you manifest project eidolon. Choose one from below. Your choice cannot be changed, and it grants your eidolon one of the additional traits indicated:

Alien Form . The exact physical dimensions of the eidolon are hard to fully comprehend. Creatures have disadvantage on attack rolls against the eidolon until they hit it.

Night Aura . The eidolon is cloaked in unnatural shadow, reducing lighting conditions around itself by one step (direct sunlight to bright light to dim light to darkness) in a 20-foot radius centered on itself. This aura does not hinder the eidolon’s own vision. Magical light produced by an effect of 3rd level or higher is unaffected by this reduction.

Temporal Warrior . The eidolon is made from a timeless essence. It becomes immune to any effect that would reduce its speed, and it has advantage on saving throws to resist any effect that would slow it or move it through time, such as the slow spell or the temporal shunt power. Additionally, on each of its turns the eidolon may shunt itself briefly through time as a bonus action, teleporting up to 30 feet to an unoccupied space it can see.

Starting at 6th level, whenever you manifest project eidolon, the eidolon you create gains an additional way to use its action, depending on the plane of thoughts you chose for the Manifest Form feature:

Alien Form. The eidolon can use its action to create a pulse of madness. Each creature within 15 feet of the eidolon must succeed on a Wisdom saving throw (against your power save DC) or be affected as though by the confusion spell until the end of their next turn. The eidolon can use this action once.

Night Aura. The eidolon can provoke a waking nightmare in one creature it can see within 60 feet. The target must succeed on a Wisdom saving throw (against your power save DC) or suffer the effects of the dissonant whispers spell as though it were cast from a 4th-level spell slot. The eidolon can use this action once.

Temporal Warrior. The eidolon can use its action to magically enfold a creature it can see within 60 feet of it in a field of null-time. The target must succeed on a Charisma saving throw (against your power save DC) or be locked in stasis. A creature locked in stasis is paralyzed, immune to damage and all other effects, and does not age. Stasis lasts indefinitely, but the target may choose to repeat the saving throw at the end of any of its turns, ending the effect on a success. The eidolon can use this action once.

Also beginning at 6th level, whenever you manifest project eidolon, the eidolon you project is automatically imbued with a modicum of your will, allowing it to sustain itself without your focus or effort. The duration of the power changes to Instantaneous when you manifest it, and the eidolon persists even if you stop focusing on imbue psicrystal, remaining in existence until it drops to 0 hit points or you dismiss it as an action. However you cannot cast imbue psicrystal while the eidolon exists, nor can you manifest a power that augments imbue psicrystal while the eidolon exists, even if you choose to maintain focus on imbue psicrystal.

The eidolon can spend its hit dice to regain hit points during a short rest, and it can take a long rest by spending 8 hours in light or no activity. It also regains a single expended use of the action granted to it by your Manifest Function feature after finishing a long rest.

Starting at 11th level, when you manifest project eidolon, you can choose to invest the eidolon you project with a silver of your sentience. You can use a bonus action, instead of an action, to command an eidolon granted this sliver of sentience. It also regains a single expended use of the action granted to it by your Manifest Function feature after finishing a short or long rest.

Investing the eidolon with a piece of your sentience is not without risks, however. Should you choose to manifest the project eidolon power this way, and the eidolon is reduced to 0 hit points, it ceases to exist and you suffer psychic backlash as part of your psyche whips back into your mind, dealing psychic damage to you equal to half the eidolon’s maximum hit point total. This damage cannot be mitigated in any way.

Starting at 14th level, whenever you manifest project eidolon, the eidolon gains improved versions of the trait you grant it with the Manifest Form feature:

Alien Form. The eidolon’s physical form is unspeakably alien and nearly impossible to fully comprehend. All creatures have disadvantage on attack rolls against the eidolon and the eidolon has advantage on all saving throws against any creature’s magical effects. If a creature deals damage to the eidolon, that creature’s attacks and magical effects are unimpeded by this feature until the start of the eidolon’s next turn.

Night Aura. The eidolon is cloaked in magical darkness in a 30-foot radius centered on itself. Only magical light produced by an effect of 8th level or higher can overcome this darkness. Additionally, magical darkness doesn’t impede the eidolon’s darkvision.

Temporal Warrior. The eidolon controls the passage of time about itself. It becomes immune to any effect that would slow it or move it through time, such as the slow spell or the temporal shunt power. Additionally, on each of its turns the eidolon may warp time around itself as a bonus action, teleporting up to 60 feet to an unoccupied space it can see, taking any object it is touching up to its maximum carrying capacity. The eidolon may also take one willing creature it is touching with it when it teleports. A creature traveling with the eidolon in this way arrives in an unoccupied space adjacent to the eidolon. If there is no such unoccupied space, neither it nor the eidolon teleport. The eidolon can take a creature with it when it teleports once, and must finish a short or long rest before it can do so again.
