Chaos Aura

A flash of colors extends from you hand to a point you choose within range. Until this spell ends a magical aura fills a 10-foot cube. Any creature in the aura's space when you cast the spell must succeed on a saving throw or take 1d6 damage of a type you choose. The saving throw is based on your chosen damage type. There is a secondary effect on creatures that failed their saving throw determined by the damage type. A creature must also make the saving throw and take on the secondary effect when it enters the aura’s space for the first time on a turn or ends its turn there. You can choose acid, cold, fire, force, lightening, necrotic, poison, psychic, radiant, or thunder damage. You can move the aura 10 feet in one direction using an action or bonus action. You can use both your action and bonus action to move the aura.

Acid (DEX save)-The creature is covered in acid for the spell's duration, or until a creature uses its action to scrape or wash the acid off itself or another creature. A creature covered in the acid takes 1d4 acid damage at start of each of its turns.
