Blight

Spell Name: Blight   MP Cost: 30   Casting Time: 1 Action   Range: 50 Feet   Target: A Creature or Plant within range   Duration: Instantaneous       Necromantic energy washes over a creature of your choice that you can see within range, draining Moisture and Vitality from it. The target must make a Constitution saving throw. The target takes 6d8 Necrotic damage on a failed save, or half as much damage on a successful one. This spell has no effect on Undeads or Constructs   If you target a plant creature or a magical plant, it makes the saving throw with disadvantage, and the spell deals maximum damage to it.   If you target a nonmagical plant that isn't a creature, such as a tree or shrub, it doesn't make a saving throw; it simply withers and dies. It deals a extra 2d20 points of damage to plant stuff.
