Calamity

You cause unimaginable destruction to occur at a location of your choosing. While casting this spell, you must imagine a precise location that is already familiar to you, where the calamity is centered. Upon casting the spell, the caster tears open a momentary rift into the boundless energy of the multiverse. An eruption of magical energy rushes forth, destroying everything within 5 miles of the source of the detonation, and significantly altering the landscape for hundreds of miles beyond that.

While the caster may specify the nature of this magical energy, they cannot control it.
