You create a column of a dark purple haze in a 60-foot-tall cylinder with a 30-foot radius centered on a point within range, which lasts until the spell ends. The area within the column is considered dim light, and the column must be oriented vertically.
Until the spell ends, on each of your turns, you can use an action to strengthen the spell with your magic. If you do so, the radius of the area grows by 10 feet for the duration. This cannot extend the radius beyond 60 feet.
At the end of each of your turns while the spell lasts, any creature within the haze can have their energy drained from them, forcing them to make a Constitution saving throw. On a failed save, a creature takes 3d8 necrotic damage, or 6d8 necrotic damage if you used your action to strengthen the spell this turn. On a successful saving throw, a creature takes half damage.
