Eldritch Flicker Strike

You turn into a flicker of void-like energy and enter the Ethereal Plane. You may move up to 60ft on the Ethereal Plane, while viewing your Original Plane in Ghostly Outlines, before emerging again. You may only move along connected Surfaces present on your Original Plane and you may not move through solid Objects.
Upon emerging you may strike a Creature within 5ft with a Melee Spell Attack. On a Hit deal 1d10 force damage.

This Spell is affected by any Eldritch Invocations that would affect the Spell Eldritch Blast, except the Eldritch Incovation Eldritch Spear which increases the Teleport distance to 90ft instead of 300ft.

The spell flickers multiple times at higher Level: Repeat this Cantrips Effect two times at 5th level, three times at 11th level, and four times at 17th level.
You can direct these Attacks at the same target or at different ones. Make a separate attack roll for each flicker.
