Mental Projection

When you gain this feature, you can project simple images in an empty space or on a fixed surface within 30 feet. The images are obviously harmless illusions, but can illustrate objects, convey simple ideas, or show items you have previously seen.

Illusory Image

Psionic Power

• Casting Time: 1 Action
• Range: 60 feet
• Components: S
• Duration: Instantaneous

You plant a construct in the mind of a creature you can see within range. The target must succeed on a Wisdom saving throw or be disoriented by the sudden appearance of the construct. The construct can take any appropriate form and affect any senses you wish, but doesn't affect the target except as described below. Select one of the following:

• The next attack roll against the target has advantage. If the attack hits, it deals an additional 1d6 damage.
• The target's next attack roll is made at disadvantage. If the attack misses, the target suffers 1d6 psychic damage.

You can spend Psi Points up to your per use limit to add the following modifiers to Illusory Image (you can add multiple modifiers). The points must be spent when choosing the target of the power.

Traumatizing (1+ psi points): If the target takes damage from this power, it takes 1d6 additional damage for each additional point spent.

Disorienting: (1 psi points): The target can't make opportunity attacks for the duration.

Enveloping (2 psi points): The target cannot make sense of the world beyond your illusory construct. It is blinded until the end of its next turn.

Intrusive: (2 psi points): The target's saving throw is Intelligence instead of Wisdom.

Alternate Effects

Additionally, when you learn the Mesmerism psionic discipline you can use your Psionics feature to cast the following spells as per the rules defined in the feature:

If a spell can be cast at a higher level, you can spend an additional psi point to cast it at that higher level.

Advantageous Assault

When you use your Illusory Image power as an action, you can make one weapon attack as a bonus action.

Imaginary Ally

(Prerequisite: Projected Self Talent)

You can project an illusion so real it cannot be differentiated from reality. As a bonus action, select one Large or smaller creature you can see within 60 feet. An illusory double of it appears within 30 feet of the target. This illusory double has the same AC and saving throws as the original, but has 1 hit point, and disappears if it is the target of any spells. It lasts for 1 minute.

While it exists, you can use your bonus action to command it to move up to its speed and make one attack. This attack uses your spell attack modifier and does 1d8 + your Intelligence modifier psychic damage on a hit. You can create a number equal to your Intelligence modifier, regaining all uses after a long rest.

Mental Broadcast

(Prerequisite: Illusory Mind subclass) When you replicate the effects of minor illusion, you can choose for the resulting illusion to be visible to any number of willing creatures within 300 feet.

Projected Self

As a bonus action, you can create a perfect illusion of yourself. This illusion requires concentration (as if you were concentrating on a spell) and lasts for 1 minute. It initially appears at a space you can see within 30 feet. As a bonus action on your turns, you can cause this illusion to move up to your speed to any space you can see within 120 feet. You can cause spells or psionic powers to appear to originate in the illusion's space, though they must still be within normal range from you. The illusion has your AC and 1 hit point, and disappears if it takes damage or is the target of any spell.

As a bonus action or as a reaction before you would take damage, you can swap places with the illusion. After you do so, the illusion disappears.

You can create an illusory duplicate in this way once, regaining its use after a long rest.

Weird is Terrible, Though?

Check out Spells That Don't Suck to find phantasmal nightmares, which is weird but good. It's also got improved alternatives for mislead and phantasmal force, too.

Illusionary Fireball

3rd-level illusion

• Classes: Sorcerer, Warlock, Wizard
• Casting Time: 1 action
• Range: 120 feet
• Components: V, S, M (something that looks like bat guano)
• Duration: Instantaneous

A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an illusionary explosion of flame. Each creature of your choice within a 20-foot radius sphere centered on that point must make a Wisdom saving throw. A target takes 6d6 psychic damage on a failed save. A creature that passes their saves realizes the fire is illusionary and takes no damage.

You can make the illusory effect an explosion of ice, lightning, or pure force energy.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.

Illusory Pit

1st-level illusion

• Classes: Bard, Sorcerer, Warlock, Wizard
• Casting Time: 1 action
• Range: 60 feet
• Components: V, S
• Duration: Concentration, up to 1 minute

You create a 5 foot radius illusory pit at a point you can see on the ground. Creatures within the radius when the spell is cast must make a Wisdom saving throw. A creature that fails their saving throw, believes they have fallen into the pit, and falls prone, cannot stand up, and is blinded beyond 5 feet of the illusory pit.

A creature can spend its action to attempt to climb out of the pit, repeating its Wisdom saving throw. On success, it spends all of its movement to stand up, and realizes the pit is an illusion, ending the spell for them. On failure, it cannot get out of the pit and continues to believe it is stuck in a pit. A creature can move within the spaces covered by the pit while under the effect.

Creatures with a flying speed are unaffected. Each time a creature under the effect takes damage, the target can make another Wisdom saving throw.

At Higher Levels. When you cast the spell using a spell slot of 2nd level or higher, the radius of the pit increases by 5 feet for each level above 1st, to a maximum of a 20 foot radius with a 4th level spell slot.
