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 could make a melee weapon attack
before the end of your current turn, you can launch a scything
blade of force from your weapon instead.

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.
