Arominar's Arcane Meteor

You draw out your hand and form a meteor no larger than 1x1 meter in size in the sky. Roll a D12 for size, anything over an 8 will gain +2 damage from increased mass. It forms like rock crystalizing and freezing in the air. The meteor emits purple, firelike energy. It takes this one turn for it to fully form. Once it has finished on your next turn, it will start to plummet from the sky, and the captured meteor will arrive and hover anywhere you choose within 15 feet of you.

At the start of your turn you can use a bonus action to move the meteor up to 20 feet in any direction or to hurl the meteor at a creature or a point you can see. Once the meteor crashes into a creature or hits something, it explodes violently, with a luminous purple radiance.

A direct hit from this meteor will knock down a creature and deal 4d6 bludgeoning damage and 5d8 Arcane damage. Creatures within 5 feet of the impact take 4d6 Arcane damage. (If a creature is taking up the space in front of the caster, it must roll a Dex save to move away from the space and upon fail will have to take damage as a direct hit from the meteor. This will also render the meteor unusable for control)

An area of ten feet within the space of the meteor impact becomes mangled and difficult to traverse, halving movement speed in this area.

At Higher Levels: You can start forming slightly larger meteors. This adds 1d6 bludgeoning damage to your damage roll.
