2-level Necromancy
You create three rays of necromantic energy and hurl them at targets within range. You can hurl them at one target or several.
Make a ranged spell attack for each ray. On a hit, the target takes 2d6 necrotic damage. If this damage reduces an organic target to 0 hit points, it dies instantly and withers into a husk. Inorganic targets such as constructs (except wood or flesh constructs) do not wither but are not immune to this spell's damage.
This spell automatically causes up to a 10 foot cube of nonmagical plants, excluding plant creatures, to wither on a hit.
When you cast this spell using a spell slot of 3rd level or higher, you create one additional ray for each slot level above 2nd.
