Breath of Xolvag

A wave of necrotic energy emanates from your outstretched hand, weathering the life force of the souls unfortunate enough stand against you.

All creatures within a 20ft cone must succeed on a constitution saving throw. On a failure they take 2d8 necrotic damage and are stunned until the end of their next turn. On a success, they take half damage and are not stunned. If an affected creature's health is at half their max or lower, they have disadvantage on the save.

Casting at higher levels:

For every level above 2nd, increase the necrotic damage by 1d8.
