Warhammer Fantasy

You call onto a massive tempest that covers the size of a mile and allows you to chose who it affects. While it is raging for ten minutes it allows you, as a bonus action, to call one of the following effects: 1: You call down a lightning that creates impact in an area 10 feet in diameter. A creature caught in it must succeed a dexterity saving throw, or suffer 10d10 lightning damage. 2: You call down a torrent of hails on an area 30 feet diameter, all that caught within, must succeed a Dexterity Saving throw or suffer 6d6 bludgeoning, and 3d6 cold damage. 3: You call down the power of the tempest that booms in a cone emanating from a spot and in a direction of your choosing. All who caught within must succeed a constitution saving throw, or suffer 8d6 thunder damage, and be thrown 10 feet away from the cone's apex. 5: Freeze the ground beneath your feet, all creatures must succeed a strength saving throw or suffer 5d6 cold damage and fall prone.
