Conjure Tempest

Dark storm clouds gather in the sky over a 100 foot tall cylinder with a 500 foot radius centered on your location, bringing with them 2 of the following effects within the spell’s area:

• Hurricane Winds: Strong winds blow in a horizontal direction of your choice, causing any creature moving against it to spend an additional 2 feet of movement for every 1 foot moved. Additionally, ranged weapon attacks that pass through the area have disadvantage. The winds hedge out any vapors or gases in the area. You may change the direction of the winds as a bonus action.

• Torrential Rain: Pouring rain extinguishes any unprotected flames in the area and limits visibility. Any object or creature located over 60 feet from a viewer is considered partially obscured, and any object or creature over 90 feet from a viewer is considered heavily obscured. Additionally, the ground within the area becomes difficult terrain.

• Blinding Snow: Snow and ice whirl about, bombarding opponents with freezing cold. Any creature that starts its turn within the spell’s area must succeed a Constitution saving throw or take 2d6 cold damage and become blinded until the start of its next turn, or half as much on a successful save and not become blinded.

• Roaring Thunder: For the duration of the spell, as a bonus action you may cause thunder to boom within a 30 foot radius sphere centered on a point you choose within the area of the spell. Creatures within the sphere must succeed a Constitution saving throw or take 4d8 thunder damage and become deafened until the end of its next turn, or half as much on a successful save and not become deafened.

• Flashing Lightning: For the duration of the spell, as a bonus action you may cause lightning to strike up to two creatures within the area of the spell. Creatures must succeed a Dexterity saving throw or take 8d12 lightning damage, or half as much on a successful save.

As an action, you may change one effect for another for as long as the spell persists.
