Death's Embrace

Extend the death side of your Boundary towards a nearby target you can see. The target will take necrotic damage equal to your wisdom bonus plus 1d4 unless they succeed on a Constitution Saving Throw, in which case they will take half damage.

The spell will deal additional damage at higher levels, (5th) plus 1d4+1, (11th) plus 2d4+2, (17th) plus 3d4+3.
