Awake to the psionic power within, a Psi Knight is a fighter who augments their physical might with psi-infused weapon strikes, telekinetic lashes, and barriers of mental force. Many githyanki train to become such knights, as do some of the most disciplined high elves. In the world of Athas, renowned gladiators in the arenas of the Sorcerer-Kings are often Psi Knights, and in Eberron, the psionic kalashtar view membership in this knighthood as a special honor.
As a Psi Knight, you might have honed your psionic abilities through solo discipline, unlocked it under the tutelage of a master, or refined it at an academy dedicated to wielding the mind's power as both weapon and shield.
3rd-level Psi Knight feature
You harbor a wellspring of psionic power within yourself, an energy that ebbs and flows as you channel it in various ways. This power is represented by your Psionic Talent die, the starting size of which is a d6.
You can use your Psionic Talent die in the following ways:
If you roll the highest number on your Psionic Talent die, it decreases by one die size after the roll. This represents you burning through your psionic energy. For example, if the die is a d6 and you roll a 6, it becomes a d4. If it's a d4 and you roll a 4, it becomes unusable until you finish a long rest.
Conversely, if you roll a 1 on your Psionic Talent die, it increases by one die size after the roll, up to its starting size. This represents you conserving psionic energy for later use. For example, if you roll a 1 on a d4, the die then becomes a d6.
Whenever you finish a long rest, your Psionic Talent die resets to its starting size. When you reach certain levels in this class, the starting size of your Psionic Talent die increases: at 5th level (d8), 11th level (d10), and 17th level (d12).
As a bonus action, you can calm your mind for a moment and restore your Psionic Talent die to its starting size. You then can't use Psi Replenishment again until you finish a long rest.
7th-level Psi Knight feature
You have mastered new ways to use your telekinesis:
10th-level Psi Knight feature
The psionic energy flowing through you has bolstered your mind and body. You have resistance to poison and psychic damage, and you are immune to the poisoned condition.
15th-level Psi Knight feature
You can shield yourself and others with telekinetic force. As a bonus action, you can choose creatures, which can include you, that you can see within 30 feet of you, up to a number of creatures equal to your Intelligence modifier (minimum of one creature). Each of the chosen creatures is protected by half cover for 1 minute or until you're incapacitated. Once you use this feature, you can't do so again until you finish a long rest, unless you decrease your Psionic Talent die by one die size to use this feature again.
18th-level Psi Knight feature
Your ability to move creatures and objects with your mind is matched by few. If your Psionic Talent die is available, you can cast the telekinesis spell, requiring no components. Your spellcasting ability for the spell is Intelligence. When you cast this spell, your Psionic Talent die decreases by one die size.
