Dissociative Edge

Formerly claimed she'd never touched him. She was truthful. Technically.
When you cast this spell, your weapon hums with violent energy. The first time you make a melee weapon attack before the end of your current turn, a scything blade of force launches forth from your weapon. Each creature within a line 5 feet wide and 30 feet long must make a Dexterity saving throw, starting from the creature closest to you. The first creature that fails takes 2d8 force damage and suffers damage and effects as though you had hit them with a successful attack using that weapon.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the force damage increases by 1d8 per slot level above 2nd.
