Be gone

This is very much like it designed for the enemy of choice to be gone you can only use this spell once but when you use it all enemy’s will have to make a dexterity saving throw (not that it really matters anyway)  if they fail they take 100d100 damage that is why it’s called be gone if the roll is successful yay good for you you take half damage so yeah it doesn’t really matter if you fail or not they will probably be gone
