Why Psi Warrior?
Playing a Gnome Psi Warrior turns you into a highly resilient, mind-powered battlefield controller. While fighters are typically known for physical prowess, this build infuses your martial skills with telekinetic magic. Your primary goal is to dictate the flow of combat, positioning enemies and shielding allies. At level 3, you unlock your Psionic Power feature, giving you a pool of energy dice to boost your damage, reduce incoming harm, or move objects with your mind. Since your stats favor physical power with a Strength of 15, these psionic maneuvers give you incredible tactical flexibility without relying solely on traditional spellcasting.
The Gnome's natural defenses synergize beautifully with the Psi Warrior's toolkit. With the Gnomish Cunning species trait, you gain advantage on Intelligence, Wisdom, and Charisma saving throws against magic. This protects you from mind-controlling spells and illusions that typically shut down heavily armored fighters. This mental fortitude, paired with your 14 Dexterity for initiative and 13 Constitution for hit points, ensures you stay standing to protect your party.
Additionally, having Darkvision means you do not need to carry a torch in dungeon depths, keeping your hands free for your weapons and shields. As you grow in power, you will become an unbreakable frontline anchor, manipulating the battlefield with psychic force while shrugging off enemy spells with ease.
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.
