Diseased Gas

A bubble of noxious gas sprouts from your caster flying towards a creature in a 10 foot area, all creatures must make a con save of 13 taking 2d8 damage, half as much on a successful roll

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.

At Higher Levels. When you cast this spell using a spell slot of 1th level or higher, the damage increases by 1d8 for each slot level above 1th.
