de Rogna's Reaping Scythe

A pitch black scythe appears and swings in a cone shape in front of you. Each creature in a 60-foot cone must make a Constitution saving throw. A creature takes 8d8 necrotic damage on a failed save, or half as much damage on a successful one. You recover an amount of hit points equal to half the damage dealt. If this damage reduces a creature to 0 hit points, that creature is killed outright and immediately becomes a zombie under your control.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d8 for each slot level above 6th.
