Blood Dash

You and what you are Wearing Instantly become a Cloud of Blood, before Traveling up to 60ft in any direction that you can see.
in a Straight line, you can pass through objects as long as they are not completely solid, if it is a creature you travel around/straight through
them like a Ghost,  Dealing 1D6 damage to yourself and 4D8+Constitution modifiers as Necrotic damage to any creature that you pass through on your way,
And as long as that Creature isn't Considered "undead or Construct" 
Draining away at their health. "Or half as much, If they succeed a Dexterity saving throw"

"Using spell slots beyond 2nd level increase the damage you deal by 1D8, 
spending a spell slot of 5th level will double the range"
