Acid Ball

You chose a creature within 60 feet of you and shoot a small ball of boiling green acid in their direction, when the acid ball is within 5 feet of the target it disperses into the air, the creature then has to make a charisma saving throw, on a failed save the target takes 4d8 fire damage and on a successful save the target takes 2d8 fire damage. 

On a miss using this spell the acid will splash on the ground 20 feet in-front of you leaving a 5 foot by 5 foot acid pool and whoever comes into contact with that pool takes 2d8 fire damage and their speed is reduced by -10 for three of their turns.
