Eldritch Sword-Burst

As part of your Attack you can brandish the weapon used in the spell’s casting and make a melee attack with it. 

The spell deals 1d10 force damage when you hit a target with it.

Plants and other thiny living things you hit with the shockwave witter and fall to dust.

When you hit an enemy with this attack, you can add some of the creaturs HP as Temp HP.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d10 force-damage to the target on a hit.  The damage roll increase by 1d10 at 11th level  and again at 17th level.

At the same time the regained temp Hp increases at 5th level to 10, at 11th level to 15 and again at 17th level to 20 temporal HP/killed target. 

This Spell replaces the Eldritch Blast for a more frontline focused combat. It´s purpose is to give the Warlock of the Undead a melee option. EB Evocations also work to upgrade this melee-spell.
