Meteor

Meteor is an attack spell that involves multiple fireballs or a single large one raining down on the earth, usually at an angle. It is often performed in conjunction with summoning a magical beast.

Its first appearance was as part of Maria Renard's Suzaku the Vermillion Bird's item crash in Castlevania: Rondo of Blood. A giant vermillion bird lifted Maria off of the surface, while countless small and large damaging meteors flew across the screen, damaging most anything on the screen (like Richter's Hydro Storm).

Nathan Graves is able to perform a similar move when summoning a Salamander by combining a Salamander Card and a Uranus Card in Castlevania: Circle of the Moon.

Juste Belmont performs the move when summoning a Warlock by combining a Summoning Tome with a Cross sub-weapon.

Desmond Belmont has a Meteor alchemy spell that he is able to perform in Castlevania: Order of Shadows. When the meteor strikes the earth, it breaks up and blankets the earth.

Alucard is able to perform a similar Hell on Earth spell in Castlevania Puzzle: Encore of the Night, which involved many Dark Inferno energy balls falling from the sky at an angle. It instantly destroys all red blocks on Alucard's board and causes damage to the opponent for each on, depending on its level.
