Roguish Archetype
Mesmerist
Not all those born with mental talents become trained psionicists. Especially when a person is touched with a strange and untrusted gift, they may feel compelled to conceal it. But such a tool is not to be ignored, and when a psionically active person turns to larcenous pursuits, their mental powers find excellent use.
Mesmerists find themselves able to access the discipline of Mesmerism, the psionic manipulation of images, sounds, and perception. It is a perfect match for the rogue's trade, creating distractions and smokescreens as they go about their work.
Mesmerist Features
| Rogue Level | Feature |
|---|---|
| 3rd | Roguish Mind, Obscuring Illusions |
| 9th | Mirror Strike |
| 13th | Defensive Duplicate |
| 17th | Mass Illusion |
Roguish Mind
When you adopt this archetype at 3rd level, your mind opens and your psionic powers are revealed. You gain proficiency with Deception, Stealth, or another rogue skill of your choice if you are already proficient. You also gain 15-foot mindsight, allowing you to see creatures with an Intelligence of 6 or higher within 15 feet as if by blindsight.
Obscuring Illusions
Also at 3rd level, you gain access to the Mesmerism discipline and the Illusory Image psionic power. You gain a number of psi points equal to your proficiency bonus, regaining them when you finish a a short or long rest. You can use these psi points to empower your Illusory Image, which has a DC equal to 8 + your proficiency bonus + your Intelligence modifier.
When you spend psi points to empor your Illusory Image, you can use it as a bonus action. If a creature fails its saving throw against your Illusory Image and you hit it with an attack on the same turn, Illusory Image's advantage and bonus damage lasts for one additional attack.
Mesmerism Discipline
Mesmerism is the ability to project your own images and thoughts into the minds of others, creating illusions and temporary projections with your psionic powers.
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 an Intelligence 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 is made with advantage. If the attack hits, it deals an additional 1d12 damage.
- The target's next attack roll is made with disadvantage. If the attack misses, the target suffers 1d12 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 1d12 additional damage for each additional point spent.
Disorienting: (1 psi points): The target's speed is halved until the end of its next turn.
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: (1+ psi points): The advantage or disadvantage caused by the power lasts for one additional attack for each additional point spent.
Mirror Strike
At 9th level, your projections can inflict devastating damage, at least in the minds of your foes. When a creature fails a saving throw against your Illusory Image, you can cause the image to stab it, inflicting psychic damage equal to a roll of half your Sneak Attack dice. Once a creature takes this damage, it can't do so again until 24 hours have passed.
Defensive Duplicate
At 13th level, your psionic powers can create illusory clones of yourself. Anytime you use your Illusory Image, you create a mirror image of yourself which copies your movements. The next time a creature hits you with an attack you before the end of your next turn, it must roll a d20. On a roll of 10 or below, the attack instead hits the duplicate and does no damage.
Mass Illusion
At 17th level, you can reach into the minds of every creature you can see. Your Illusory Image power gains a new modifier which you can apply:
Mass: (1-4 psi points): You can target every creature of your choice within 15 feet of you. This range increases by 15 feet for each additional point spent.
You gain 4 special psi points which you can only spend on this modifier. You regain these special psi points after finishing a long rest.

Appendix 1: 5e++
If you're playing with the 5e++ ruleset by KibblesTasty, it adds an additional subclass feature for rogues at 5th level. In order to make the Mesmerist compatible, make the following adjustments.
Illusion Magic
At 5th level, you learn the spells silent image, disguise creatureS, and major image. You can cast each one once without expending a spell slot. After you cast one of these spells in this way, you can't cast it again until you finish a long rest, unless you spend psi points equal to the spell's level.
