Boo's Miniature Giant Meteor Swarm

You create 10 tiny meteors in your space. They float in the air and orbit you for the spells duration. As a bonus action on each of your turns thereafter — you can expend any number of the meteors, sending them streaking toward a creature or creatures you choose within 90 feet of you. The meteors hit each creture automatically, dealing 1 point of force damage.

As a reaction to a creature hitting you with a melee attack, while at least 1 meteor remains, you can send any number of the remaining meteors to hit that creature.

While this spell is active, if you cast Melf's Minute Meteors, the meteors that remain ignite in a fiery blaze and streak towards creatures of your choice that you can see within range, dealing an extra 1 point of fire damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the number of meteors created increases by 4 for each slot level above 3rd.
