Elemental Lances

Enormous lances of elemental energy plummet to the ground at four different points you can see within range and then disappear. Each creature in a 20-foot-radius, 100-foot-high cylinder centered on each point must make a Dexterity saving throw. On a failed save, a creature takes 4d8 damage of each of the following types: acid, cold, fire, lightning, poison, and thunder. On a successful save, a creature takes half as much damage. A creature in the area of more than one lance is affected only once.
