Unnatural Causes

4th-Level Necromancy

Casting Time: 1 action
Range: 120 feet
Components: V, S
Duration: Concentration, up to 10 minutes

You cause vengeful spirits of the wrongfully slain to manifest in a 30-foot-radius sphere centered on a point you choose within range. The sphere of spirits spreads around corners and lasts until the spell ends.

When a creature enters the spell’s area for the first time on a turn or starts its turn there, that creature must make a Wisdom saving throw. On a failed save, a creature takes 3d6 cold and 3d6 necrotic damage and has disadvantage on attack rolls until the end of its next turn. On a successful save, a creature takes half the damage and doesn’t have disadvantage on attack rolls.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the cold damage or necrotic damage (your choice) increases by 1d6 for each slot level above 4th.
