Fallen Soul

The dead do not rest easily when the clash of steel rings loudly.
You summon forth an ethereal wraith-like phantom armed with a deadly blade at a point within range to strike down your foes. When you cast this spell, and as an action on each of your subsequent turns until the spell ends, you can direct the phantom to fly up to 30 feet and attack a creature within 5 feet of it with its blade. The target must make a Dexterity saving throw. A target that is frightened makes this saving throw with disadvantage. If they fail, the phantom strikes them, inflicting 3d10 slashing damage.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the slashing damage increases by 1d10 per spell slot level above 3rd.
