Psi Blade
Evocation Cantrip
Casting Time: 1 action
Range: Self
Components: SM* (a melee weapon)
Duration: 1 round
Target. One creature within the reach of your weapon.
Attack Roll. Melee weapon attack with the weapon used to cast the spell.
Hit. The weapon attack's normal damage, and a logic bomb is planted in the creature's mind until the start of your next turn. If the target speaks, such as to cast a spell with a verbal component, before your next turn, it immediately takes 1d8 psychic damage and the spell ends.
Cantrip Progression. This spell's damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d8 psychic damage to the target, and the damage the target takes for being hit with an attack increases to 2d8. Both damage rolls increase by 1d8 at 11th level, 17th level, 23rd level, and 28th level.
