Crashing Atlas

Holding your hand high above your head like as if you were wielding a greatsword, a large spectral sword begins to form in your hands. You make a spell attack roll against target creature you can see within range. Sundering both body and spirit as the greatsword cuts through them, dealing 3d8 force damage on hit. 

This spell calls upon Atlas the Warrior, as he imparts a piece of his strength to you, resulting in this spell only able to be cast while actively in combat. This spell can be charged to deal greater damage. The spell can be ended prematurely if the caster's concentration is broken before releasing the spell, resulting in the spell fizzling out and having no effect. If the castor begins to charge the spell, on their next turn they can use their action to finish the spell, the respective damage based on the number of rounds charged is shown below.
