Mind Blast: As an action, you can magically emit psychic energy in a 15-foot cone. Each creature in that line must make an Intelligence saving throw. The DC for this saving throw equals 8 + your Intelligence modifier + your proficiency bonus. A creature takes 1d6 psychic damage on a failed save and half as much damage on a successful one. The damage increases to 2d6 at 6th level. 3d6 at 11th level, and 4d6 at 16th level. After you use this ability, you can't use it again until you complete a short or long rest. This feature also stunds the target on a failed save for one round. Two runds at 6th level, three rounds at 11th level and four rounds at 16th level. While the stunned, the target can make Intelligence saves to break out of it.
