Circle of Corruption

You focus raw necrotic energy to expand beyond yourself. You extend both hands to the left and right and slap them together. Creating a dark wave that expands from within you. Each creature in a 50-foot radius originating from you must make a Constitution saving throw. A creature takes 4d8 necrotic damage on a failed save, or half as much damage on a successful one.

When a creature is slain by this spell, it is raised as an undead zombie until the end of combat. The power of this spell is limited to having two active zombies at once.

At Higher Levels. When you cast this spell using a spell slot of 3nd level or higher, the damage increases by 1d8 for each slot level above 3rd.
