You attempt to disrupt the molecular structure of one creature or object you can see within range.  The target must succeed on a Constitution saving throw or take 1d6 necrotic damage. This damage counts as force damage for the purposes of vulnerability and resistance, but not immunity. 

If this damage reduces the target to 0 hit points, it dies and is reduced to its component atoms. 

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
