At 3rd level, you can use a bonus action to magically manifest an echo of yourself in an unoccupied space you can see within 15 feet of you. This echo is a magical, translucent, gray image of you that lasts until it is destroyed, until you dismiss it as a bonus action, until you manifest another echo, or until you're incapacitated.
Your echo has AC 14 + your proficiency bonus, 1 hit point, and immunity to all conditions. If it has to make a saving throw, it uses your saving throw bonus for the roll. It is the same size as you, and it occupies its space. On your turn, you can mentally command the echo to move up to 30 feet in any direction (no action required). If your echo is ever more than 30 feet from you at the end of your turn, it is destroyed.
As a bonus action, you can teleport, magically swapping places with your echo at a cost of 15 feet of your movement, regardless of the distance between the two of you.
When you take the Attack action on your turn, any attack you make with that action can originate from your space or the echo's space. You make this choice for each attack.
When a creature that you can see within 5 feet of your echo moves at
least 5 feet away from it, you can use your reaction to make an opportunity attack against that creature as if you were in the echo's space.
Beginning at 1st level, you know how to strike subtly and exploit a foe's distraction. Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon.
You don't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll.
Starting at 2nd level, your quick thinking and agility allow you to move and act quickly. You can take a bonus action on each of your turns in combat. This action can be used only to take the Dash, Disengage, or Hide action.
When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.
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.
Starting at 2nd level, you can push yourself beyond your normal limits for a moment. On your turn, you can take one additional action.
Once you use this feature, you must finish a short or long rest before you can use it again. Starting at 17th level, you can use it twice before a rest, but only once on the same turn.
You create a 20-foot-radius sphere of fog centered on a point within range. The sphere spreads around corners, and its area is heavily obscured. It lasts for the duration or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it.
Once you cast a spell with this trait, you can’t cast that spell with it again until you finish a long rest. Charisma is your spellcasting ability for these spells.
When your nonpsionic training fails you, your psionic power can help: if you fail an ability check using a skill or tool with which you have proficiency, 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.
You can establish telepathic communication between yourself and others — perfect for quiet infiltration. As an action, choose one or more creatures you can see, up to a number of creatures equal to your proficiency bonus, and then roll one Psionic Energy die. For a number of hours equal to the number rolled, 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.
The first time you use this power after each long rest, you don't expend the Psionic Energy die. All other times you use the power, you expend the die.
Also at 3rd level, You can manifest your psionic power as shimmering blades of psychic energy. Whenever you take the Attack action, you can manifest a psychic blade from your free hand and make the attack with that blade. This magic blade is a simple melee weapon with the finesse and thrown properties. It has a normal range of 60 feet and no long range, and on a hit, it deals psychic damage equal to 1d6 plus the ability modifier you used for the attack roll. The blade vanishes immediately after it hits or misses its target, and it leaves no mark on its target if it deals damage.
After you attack with the blade, you can make a melee or ranged weapon attack with a second psychic blade as a bonus action on the same turn, provided your other hand is free to create it. The damage die of this bonus attack is 1d4, instead of 1d6
At 3rd level, as a bonus action, you give yourself advantage on your next attack roll on the current turn. You can use this bonus action only if you haven't moved during this turn, and after you use the bonus action, your speed is 0 until the end of the current turn
At 3rd level, you can heighten your echo's fury. Whenever you take the Attack action, you can make one additional melee attack from the echo's position.
You can use this feature a number of times equal to your Constitution modifier (a minimum of once). You regain all expended uses when you finish a long rest.
