Tormented Shadow

Choose a point within range. The ground in a 5-foot radius of that point ignites in dark flames. When a creature starts its turn in the area or enters the area for the first time on a turn it must make a dexterity saving throw. a creature with less than half of its maximum hit points has disadvantage on this save. On a failed save the creature takes 3d4 necrotic damage or fire damage (your choice when you cast the spell), or half as much on a successful one.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d4 damage for each slot above 2nd.
