Vik's Meteor Barrier

You create six tiny meteors in your space. They float in the air and orbit you for the spell’s duration. When you cast the spell — and as a reaction on each of your turns thereafter — you can expend one or two meteors, sending them streaking towards an enemy spell or melee weapon attack to intercept it. You can expend 1-2 meteors as a reaction to gain 1d6 temporary hit points for each meteor expended until the beginning of your next turn.

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