Dark Meteor (5e Spell)
From D&D Wiki
An invisible orb of shadowy space matter plummets to the ground at a point you can see within range and then explodes. Each creature in a 40-foot radius sphere of that point must make a Dexterity saving throw, taking 20d6 force damage and 20d6 bludgeoning damage on a failed save, or half as much on a successful one. The area of effect spreads around corners.
A creature that fails its saving throw must also make a Strength saving throw, getting flung 30 feet directly away from the point and getting knocked prone on a failed save.
The projectile summoned by this spell is made of invisible dark matter. Creatures have disadvantage on their saving throw and can't react to it unless they have an ability that lets them see the invisible, such as truesight or the see invisibility spell.
