Why Psi Warrior?
The Tiefling Psi Warrior is a fantastic blend of supernatural heritage and mental discipline. As a Fighter, your main job is to control the battlefield and protect your allies. The Tiefling's Fiendish Legacy trait grants you natural resistance to fire damage, which is incredibly valuable because it keeps you standing longer on the front lines without needing constant healing from your party.
By choosing the Psi Warrior subclass, you unlock Psionic Power at level 3, which allows you to manipulate objects and enemies with your mind. Even with a high Strength score of 15 to power your physical attacks, you can use your psionic energy to mitigate damage for your allies or boost your own strikes. Your Darkvision trait also ensures that you can see threats in the dark up to 60 feet, allowing you to position yourself perfectly to control the fight before the enemy even knows you are there.
As you level up, you will become a true anchor for your team. You will use your mental energy to shield your friends, move objects, and lock down dangerous foes. This build perfectly balances the raw physical power of a martial warrior with the tactical, mind-over-matter control of a telekinetic master.
Psi Warrior Features
Psionic Power
Level 3You can use your mind to enhance your body. When you finish a Long Rest, you gain a number of Psionic Energy dice equal to twice your Proficiency Bonus. These dice are d6s. You can use these dice to power your psionic abilities. A die is expended when you use it. You regain all expended Psionic Energy dice when you finish a Long Rest. When you reach certain fighter levels, the size of your Psionic Energy dice increases: at 5th level (d8), 11th level (d10), and 17th level (d12). The following options show how you can use your Psionic Energy dice.
Telekinetic Adept
Level 7You can use an action to spend 1 Psionic Energy die to move a creature or object you can see within 30 feet of yourself. Roll the Psionic Energy die. The creature or object moves 5 feet × the number rolled on the die. As an action, you can spend 1 Psionic Energy die to attempt to knock a creature prone or push it away. The target must make a Strength saving throw (DC = 8 + your Strength modifier + your Proficiency Bonus). On a failed save, it takes force damage equal to 1d6 + your Strength modifier and is either knocked Prone or pushed 5 feet away, depending on which effect you choose.
Guarded Mind
Level 10You can use an action to spend 1 Psionic Energy die to gain Advantage on saves against magic you can see being cast within 30 feet of yourself. You can use this ability after you see the save but before you roll the die.
Bulwark of Force
Level 15When another creature you can see within 30 feet of yourself takes damage, you can use your Reaction and spend 1 Psionic Energy die to shield that creature. Roll the die, and the creature takes less damage by the number rolled.
Telekinetic Master
Level 18You can use your Telekinetic Adept ability a number of times equal to your Proficiency Bonus without expending Psionic Energy dice. You regain all expended uses of this ability when you finish a Short or Long Rest.
