Calamities

You shout the name of a creature you can see within range. That creature must succeed on a Charisma saving throw or it is struck with bad luck that last until the spell end. The targeted creature has disadvantage on all it's roll. When the target fails an attack rolls, ability check or saving throw, bad luck struck it and it take 10d10 bludgeoning damage. The creature must also make a Dexterity saving throw whenever it move 10 feet or more in a single turn. If it fail, it fall prone and take 5d10 bludgeoning damage.
