Cataclysm

This world-breaking spell calls towards the heavens to attract a massive asteroid 150 ft in all dimensions and cause it to crash down upon terra firm. After casting, it takes 3 minutes for the asteroid to hit impact. After minute 1, it appears in the sky, and by the second minute it begins to blot out the sun. Upon impact of any kind, the asteroid deals 32d10+160 Bludgeoning damage. This damage is magical and if a creature is immune to bludgeoning damage they are resistant to the damage instead.
