Verdigris Vengence

Twisting, thorny vines erupt from the ground at four different points you can see within range. Each creature in a 40-foot-radius sphere centered on each point you choose must make a Strength saving throw. The sphere spreads around corners. A creature takes 20d6 piercing damage and 20d6 bludgeoning damage on a failed save, or half as much damage on a successful one. A creature in the area of more than one nature incursion is affected only once.

The spell damages objects in the area and makes the affected terrain difficult until the magical flora can be cleared away and repairs are made.
