Chilling Scythe

You create a scythe of necrotic energy in your free hand. The scythe is similar in size and shape to an agricultural scythe, and it lasts for the duration. If you let go of the scythe, it disappears, but you can create the scythe again as a bonus action.

You can use your action to make a melee spell attack with the necrotic scythe. On a hit, the target takes 3d6 necrotic damage.

If you hit an undead target with the necrotic scythe, it must make a Strength saving throw or be pushed 20 feet away from you in a straight line.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for every two slot levels above 2nd.
