Psionic Ability

At 3rd level,  you harbor a wellspring of psionic energy within yourself. This energy is represented by your Psionic Energy dice, which are each a d6. You have a number of these dice equal to twice your proficiency bonus, and they fuel various psionic powers you have, which are detailed below.

Some of your powers expend the Psionic Energy die they use, as specified in a power's description, and you can't use a power if it requires you to use a die when your dice are all expended. You regain all your expended Psionic Energy dice when you finish a long rest. In addition, as a bonus action, you can regain one expended Psionic Energy die, but you can't do so again until you finish a short or long rest.

When you reach certain levels in this class, the size of your Psionic Energy dice increases: at 5th level (d8), 11th level (d10), and 17th level (d12).

Telepathic Insight: In battle, you can briefly see into your opponent's mind, in order to gain some insight into their defenses. Once on each of your turns, after you make an attack roll, you can expend one of your Psionic energy die and add it to the roll. When you get to 5th level in this class, You only expend the Psionic Energy Die when this causes the attack to hit.

Psychic Defenses:  You can use your Telekinetic abilities to anticipate your opponents attacks. As a reaction when you are hit by an attack, you can roll one of your Psionic energy die, and increase your AC by the number rolled for that attack, potentially causing the attack to miss. 

Supernatural Insight: Your Psychic powers allow you to sense the emotions of the people around you.  if you fail a Perception or Insight check, you can roll one Psionic Energy die and add the number rolled to the check, potentially turning failure into success. You expend the die only if the roll succeeds. Additionally, you can roll 1 psionic energy die and add the number rolled to your passive perception for 1 hour.

 

Cerebral Detection

At 7th level, you can sense the presence of all creatures around you. As an action, you can sense exactly how many of each creature type there are within 1000ft of you, and if there are any of your favored enemy within the area, you know the direction and distance of each one of them. Also, for your favored enemies, you can expend one Psionic energy die in order to tell the species of the creatures, ie the difference between a Hobgoblin and a goblin, but not the stat block itself, so, for example, you couldn't tell the difference between a Goblin and a Goblin Boss. You can use this ability once per long rest.

Telepathic Awareness

At 11th level, you gain the ability to open up your mind in order to communicate with the innate psychic forces around the world. You can communicate to the force in this way, as if casting Contact Other Plane as a ritual.

You also gain proficiency in Intelligence Saving Throws. If you already are proficient, then you gain proficiency in either Wisdom or Charisma Saves.

Psychic Assassin

You have gained the ability to defeat your enemies with nothing but your psychic prowess. When you expend a Psionic Energy die, you can use your reaction immediately deal psychic damage equal to your level to one creature within 30 feet of you. You can expend another Psionic Energy die when you use this ability to make it require no action at all.
