You have a limited well of stamina that you can draw on to protect yourself from harm. On your turn, you can use a bonus action to regain hit points equal to 1d10 + your fighter level.
Once you use this feature, you must finish a short or long rest before you can use it again.

Darkvision. You can see in dim light within 60 feet of you as if it were bright light and in darkness as if it were dim light. You discern colors in that darkness as shades of gray.

Deathless Nature. You don't need to breathe.

Spider Climb. You have a climbing speed equal to your walking speed. In addition, at 3rd level, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.

Vampiric Bite. Your fanged bite is a natural weapon, which counts as a simple melee weapon with which you are proficient. You add your Constitution modifier, instead of your Strength modifier, to the attack and damage rolls when you attack with this bite. It deals 1d4 piercing damage on a hit. While you are missing half or more of your hit points, you have advantage on attack rolls you make with this bite.
When you attack with this bite and hit a creature that isn’t a Construct or an Undead, you can empower yourself in one of the following ways of your choice:
You regain hit points equal to the piercing damage dealt by the bite.
You gain a bonus to the next ability check or attack roll you make; the bonus equals the piercing damage dealt by the bite.
You can empower yourself with this bite a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

No matter where you go, people are afraid of you due to your reputation. When you are in a civilized settlement, you can get away with minor criminal offenses, such as refusing to pay for food at a tavern or breaking down doors at a local shop, since most people will not report your activity to the authorities.

You have a number of "Psionic Detection" points equal to your proficiency bonus. You regain your expended points after a long rest. You can spend them on one of these abilities:
-Spend 1 point to add +5 to your AC as a reaction.
-Spend 2 to cast the spells Locate Object, Locate Animals or Plants, or See Invisibility.
-Spend 3 to add +5 to your passive perception for 1 hour.
-Spend 4 to cast the spell Locate Creature.

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).

The powers below use your Psionic Energy dice.

Protective Field. When you or another creature you can see within 30 feet of you takes damage, you can use your reaction to expend one Psionic Energy die, roll the die, and reduce the damage taken by the number rolled plus your Intelligence modifier (minimum reduction of 1), as you create a momentary shield of telekinetic force.

Psionic Strike. You can propel your weapons with psionic force. Once on each of your turns, immediately after you hit a target within 30 feet of you with an attack and deal damage to it with a weapon, you can expend one Psionic Energy die, rolling it and dealing force damage to the target equal to the number rolled plus your Intelligence modifier.

Telekinetic Movement. You can move an object or a creature with your mind. As an action, you target one loose object that is Large or smaller or one willing creature, other than yourself. If you can see the target and it is within 30 feet of you, you can move it up to 30 feet to an unoccupied space you can see. Alternatively, if it is a Tiny object, you can move it to or from your hand. Either way, you can move the target horizontally, vertically, or both. Once you take this action, you can't do so again until you finish a short or long rest, unless you expend a Psionic Energy die to take it again.
