Eldritch Implosion

A wave of eldritch energy implodes onto a point of your choice within range. Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. On a failed save, the creature takes 2d8 force damage and is pulled in horizontally toward the center of the sphere, ending in an unoccupied space as close to the center as possible (even if that space is in the air). On a successful save, the creature takes half as much damage and isn't pulled.

Before the end of your next turn, you may use a bonus action to release the stored eldritch implosion as an explosion at a point within 20ft of the center of the implosion. Each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. On a failed save, the creature takes 2d8 force damage and is pushed horizontally 15ft away. On a successful save, the creature takes half as much damage and isn't pushed.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the implosion and explosion damage each increase by 1d8 for each slot level above 2nd.
