Cataclysm

You call upon the unimaginable power of world-ending cataclysms, ripping a small piece of each cataclysm and combining them together into one horrifically powerful attack. The following effects come down upon all creatures in the area. Each creature in range must make a dexterity save, taking the below-listed damage on a failed save, or half as much on a successful save. Any creature with immunity to any of the following damage types still takes damage as though they instead have resistance and any creature with resistance takes full damage, ignoring resistance.

• Flesh-dissolving acid rain deals 3d10 acid damage.
• A roaring earthquake shakes and bludgeons creatures on the ground, dealing 3d10 bludgeoning damage.
• A blast of freezing wind deals 3d10 cold damage.
• Incredible lightning lashes the area, dealing 3d10 lightning damage.
• Beating winds churn across the sky, dealing 3d10 bludgeoning damage to creatures flying in the area and causing any flying creature to make a constitution save or fall to the ground.
• An instant tsunami sweeps over creatures in the area, dealing 3d10 bludgeoning damage and making the affected area difficult terrain.
• A massive wildfire burns in a sudden inferno, dealing 3d10 fire damage.
