Conjure Grim Scythe

You create a Grim Scythe, Blessed upon thee by the Raven Queen, that hovers within range. It lasts until Concentration is broken. (Make checks when attacked)

When the Grim Scythe appears, you make a melee spell attack against a target of your choice within 5 feet of the sword. On a hit, the target takes 1d12 Necrotic damage. Until the spell ends, you can use a bonus action on each of your turns to move the sword up to 20 feet to a spot you can see and repeat this attack against the same target or a different one.

Spell Increases in damage; 3rd level (1d12), 6th level (2d12), 9th level (3d12), 12th level  (4d12), 15 level (5d12), 18 level (6d12).
