Carian Slicer

Summon a cerulean spectral blade in your hand or through your spell casting focus, dealing an attack that deals 1d10 force damage. 

at higher levels: at level 5, 11, and 17 you can attack an additional time with this similar to the beams of eldritch blast.

For example, when you consume an action to cast this at level 5 you can make 2 attacks with your carian slicer, each dealing 1d10 force damage.
