Wyrd Reconstruction

You touch a creature and its flesh begins to writhe, closing wounds with an unnatural vigor that sometimes rips the flesh in new ways. The target regains 2d10 -2 hit points, then that creature must succeed on a DC12 Constitution saving throw or take 2d4 Necrotic damage.

At Higher Levels: When casting using a 2nd level spell slot or higher, the target regains an additional 1d10 - 1 hit points, the Constitution saving throw DC increases by 1, and the necrotic damage from failing the save increases by 1d4.
