Your control over your body allows you to deliver acid or poison attacks.
Psychic Focus. While focused on this discipline, you have resistance to acid and poison damage
Corrosive Touch (1-7 psi). As an action, you deliver a touch of acid to one creature within your reach. The target must make a Dexterity saving throw, taking 1d10 acid damage per psi point spent on a failed save, or half as much damage on a successful one.
Venom Strike (1-7 psi). As an action, you create a poison spray that targets one creature you can see within 30 feet of you. The target must make a Constitution saving throw. On a failed save, it takes 1d6 poison damage per psi point spent and is poisoned until the end of your next turn. On a successful save, the target takes half as much damage and isn’t poisoned.
Acid Spray (2 psi). As a reaction when you take piercing or slashing damage, you cause acid to spray from your wound; each creature within 5 feet of you takes 2d6 acid damage.
Breath of the Black Dragon (5 psi). You exhale a wave of acid in a 60-foot line that is 5 feet wide. Each creature in the line must make a Constitution saving throw, taking 6d6 acid damage on a failed save, or half as much on a successful one. You can increase the damage by 1d6 per additional psi point spent on it.
Breath of the Green Dragon (7 psi). You exhale a cloud of poison in a 90-foot cone. Each creature in the line must make a Constitution saving throw, taking 10d6 poison damage on a failed save, or half as much damage on a successful one.
