Echoes of Extinction

Make a melee attack with the Scythe of Extinction against one creature within 10 feet of you.

On a hit, a projection of you appears and makes an additional attack against that target using the Scythe of Extinction. The projection has the same attack modifiers as you but deals half damage.
Until the start of your next turn, any time the target moves (willingly or not) the projection reappears and makes another attack. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the first projection makes an additional attack for each slot level above 1st.
