tungsten transformation

turn an object or a part of a person in to tungsten by imbuing you magic image into it. The target must make a Constitution saving throw. The target takes 6d6 force dmg on a failed save and becomes prone for two turns, or half as much damage on a successful one. 

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 becomes tungsten and dies.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2d6 for each slot level above 4th.
