Psionic Assassin

Through the study of the mind flayers, aboleths, and intellect devourers Telizar the Vexxed wanted to make the perfect assassin by manipulating the mind of humanoid creatures and trying to infuse them with psionic powers. He failed many, many times bodies of all races until finally a young elf child fell into the lap of Telizar and after he completed the infusion the boy still stood with life still in him. Telizar began studying and running experiments on the boy. After unlocking the boys power he began to train him as an assassin. Something was quite right though. The boy began to develop a fascination with playing cards, and was able to use them as a channel for his power. 

Psionic Talent

You harbor a wellspring of psionic power within yourself, an energy that ebbs and flows as you channel it in various ways.

To activate your abilities you consume a psychic talent point. Your total psychic talent points are equal to your rogue lvl + your INT modifier + your proficiency modifier. 

This power is represented by your Psionic Talent die, the starting size of which is a d4. At lvl 9 the die increase to d6, and at lvl 15 the die increases to a d8, and at lvl 17 the die increase to a d10.

Psi-Bolstered Knack. When your non-psionic training fails you, you can tap into your psionic power to help: if you fail an ability check using a skill or tool with which you have expertise, consume a psionic talent point you can roll your Psionic Talent die and add the number rolled to the check, potentially turning failure into success.

Psychic Whispers. Consume a psionic talent point you can use your psychic abilities to establish telepathic communication between yourself and others—perfect for quiet infiltration. As an action, you give yourself and at least one other creature the ability to speak telepathically with each other. When you do so, roll your Psionic Talent die, and choose creatures you can see, up to a number of creatures equal to the number rolled. For 1 hour, the chosen creatures can speak telepathically with you, and you can speak telepathically with them. To send or receive a message (no action required), you and the other creature must be within 1 mile of each other. A creature can’t use this telepathy if it can’t speak any languages, and a creature can end the telepathic connection at any time (no action required). You and the creature don’t need to speak a common language to understand each other.
